GM1 NCO.GEN.100(b) Competent authority DETERMINING THE PLACE WHERE AN OPERATOR IS RESIDING The concept of ‘place where the operator is residing’ is mainly addressed to a natural person. The place where the operator resides is the place where the operator complies with his or her tax obligations. Several criteria can be used to help determining a person’s place of residence. These include, for example: (a) the duration of a person’s presence on the territory of the countries concerned; (b) the person’s family status and ties; (c) the person’s housing situation and how permanent it is; (d) the place where the person pursues professional or non-profit activities; (e) the characteristics of the person’s professional activity; (f) the Member State where the person resides for taxation purposes. NCO.GEN.101 Means of compliance Alternative means of compliance to those adopted by the CAA may be used by an operator to establish compliance with MCAR Air Operations and its Implementing Rules. NCO.GEN.103 Introductory flights Introductory flights when conducted in accordance with this Annex, shall: (a) start and end at the same aerodrome or operating site; (b) be operated under VFR by day; (c) be overseen by a nominated person responsible for their safety; and Issue 1.00 Page 8 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (d) comply with any other conditions stipulated by the CAA. NCO.GEN.104 Use of aircraft included in an AOC by an NCO operator (a) An NCO operator may use other than complex motor-powered aircraft listed on an operator's AOC to conduct non-commercial operations in accordance with part NCO. (b) The NCO operator using the aircraft in accordance with point (a) shall establish a procedure: (1) clearly describing how operational control of the aircraft is transferred between the AOC holder and the NCO operator, as referred to in point ORO.GEN.310 of Annex III; (2) describing the handover procedure of the aircraft upon its return to the AOC holder. That procedure shall be included in a contract between the AOC holder and the NCO operator. The NCO operator shall ensure that the procedure is communicated to the relevant personnel. (c) The continuing airworthiness of the aircraft used pursuant to point (a) shall be managed by organisation responsible for the continuing airworthiness for the aircraft included in the AOC, in accordance with MCAR-M. (d) The NCO operator using the aircraft in accordance with point (a) shall ensure the following: (1) that every flight conducted under its operational control is recorded in the aircraft technical log system; (2) that no changes to the aircraft systems or configuration are made; (3) that any defect or technical malfunction occurring while the aircraft is under its operational control is reported to the organisation referred to in point (c) immediately after the flight; (4) that the AOC holder receives a copy of any occurrence report related to the flights performed with the aircraft, completed in accordance with Regulation (EU) No 376/2014 and Regulation (EU) 2015/1018.

The information about any defect or malfunction should be transmitted to the CAMO/CAO of the AOC holder before the aircraft is used for the next flight. The same information should be confirmed by the entries in the aircraft technical log system; and Issue 1.00 Page 9 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (2) to report any occurrence in accordance with the applicable rules and the internal procedures; and (c) the way in which the operator deals with failures and defects identified before the flight. GM1 NCO.GEN.104 Use of aircraft included in an AOC by an NCO operator SCOPE As per SPO.GEN.005(b), operators performing non-commercial specialised operations with other than complex motor-powered aircraft will comply with Part-NCO. Thus, such operators are also covered by NCO.GEN.104. GM1 NCO.GEN.104(c) Use of aircraft included in an AOC by an NCO operator CONTINUING AIRWORTHINESS MANAGEMENT In accordance with Part-M and Part-ML to MCAR-M, the management of the continuing airworthiness of the aircraft by the CAMO/CAO of the AOC holder means that the NCO operator has established a written contract as per Appendix I to Part-M or Appendix I to Part-ML with this CAMO/CAO. NCO.GEN.105 Pilot-in-command responsibilities and authority (a) The pilot-in-command shall be responsible for: (1) the safety of the aircraft and of all crew members, passengers and cargo on board during aircraft operations as referred to in 1.3 of MCAR Air Operations, ERO.OPS.120. (2) the initiation, continuation, termination or diversion of a flight in the interest of safety; (3) ensuring that all operational procedures and checklists are complied with as referred to in 1.2 of MCAR Air Operations, ERO.OPS.120. (4) only commencing a flight if he/she is satisfied that all operational limitations referred to in 2(c) of MCAR Air Operations, ERO.OPS.120 are complied with, as follows: (i) the aircraft is airworthy; (ii) the aircraft is duly registered; (iii) instruments and equipment required for the execution of that flight are installed in the aircraft and are operative, unless operation with inoperative equipment is permitted by the minimum equipment list (MEL) or equivalent document, if applicable, as provided for in points NCO.IDE.A.105 or NCO.IDE.H.105; (iv) the mass of the aircraft and the centre of gravity location are such that the flight can be conducted within limits prescribed in the airworthiness documentation; (v) all equipment, baggage and cargo are properly loaded and secured and an emergency evacuation remains possible; (vi) the aircraft operating limitations as specified in the aircraft flight manual (AFM) will not be exceeded at any time during the flight; and Issue 1.00 Page 10 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (vii) any navigational database required for PBN is suitable and current; (5) not commencing a flight if he/she is incapacitated from performing duties by any cause such as injury, sickness, fatigue or the effects of any psychoactive substance; (6) not continuing a flight beyond the nearest weather-permissible aerodrome or operating site when his/her capacity to perform duties is significantly reduced from causes such as fatigue, sickness or lack of oxygen; (7) deciding on acceptance of the aircraft with unserviceabilities in accordance with the configuration deviation list (CDL) or minimum equipment list (MEL), as applicable; and (8) recording utilisation data and all known or suspected defects in the aircraft at the termination of the flight, or series of flights, in the aircraft technical log or journey log for the aircraft. (b) The pilot-in-command shall ensure that during critical phases of flight or whenever deemed necessary in the interest of safety, all crew members are seated at their assigned stations and do not perform any activities other than those required for the safe operation of the aircraft. (c) The pilot-in-command shall have the authority to refuse carriage of or disembark any person, baggage or cargo that may represent a potential hazard to the safety of the aircraft or its occupants. (d) The pilot-in-command shall, as soon as possible, report to the appropriate air traffic services (ATS) unit any hazardous weather or flight conditions encountered that are likely to affect the safety of other aircraft. (e) The pilot-in-command shall, in an emergency situation that requires immediate decision and action, take any action he/she considers necessary under the circumstances in accordance with 7.3 of MCAR Air Operations, ERO.OPS.120. In such cases he/she may deviate from rules, operational procedures and methods in the interest of safety. (f) During flight, the pilot-in-command shall: (1) keep his/her safety belt fastened while at his/her station; and (2) remain at the controls of the aircraft at all times except if another pilot is taking the controls. (g) The pilot-in-command shall submit a report of an act of unlawful interference without delay to the competent authority and shall inform the designated local authority. (h) The pilot-in-command shall notify the nearest appropriate authority by the quickest available means of any accident involving the aircraft that results in serious injury or death of any person or substantial damage to the aircraft or property. AMC1 NCO.GEN.105 Pilot-in-command responsibilities and authority FLIGHT PREPARATION FOR PBN OPERATIONS (a) The pilot-in-command should ensure that RNAV 1, RNAV 2, RNP 1, RNP 2, and RNP APCH routes or procedures to be used for the intended flight, including for any alternate aerodromes, are selectable from the navigation database and are not prohibited by NOTAM. (b) The pilot-in-command should take account of any NOTAMs or pilot-in-command briefing material that could adversely affect the aircraft system operation along its flight plan including any alternate aerodromes. (c) When PBN relies on GNSS systems for which RAIM is required for integrity, its availability should be verified during the preflight planning. In the event of a predicted continuous loss of fault detection Issue 1.00 Page 11 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL of more than five minutes, the flight planning should be revised to reflect the lack of full PBN capability for that period. (d) For RNP 4 operations with only GNSS sensors, a fault detection and exclusion (FDE) check should be performed. The maximum allowable time for which FDE capability is projected to be unavailable on any one event is 25 minutes. If predictions indicate that the maximum allowable FDE outage will be exceeded, the operation should be rescheduled to a time when FDE is available. (e) For RNAV 10 operations, the pilot-in-command should take account of the RNAV 10 time limit declared for the inertial system, if applicable, considering also the effect of weather conditions that could affect flight duration in RNAV 10 airspace.

GM1 NCO.GEN.120 Rotor engagement INTENT OF THE RULE (a) The following two situations where it is allowed to turn the rotor under power should be distinguished: (1) for the purpose of flight, this is described in the implementing rule; (2) for maintenance purposes. (b) Rotor engagement for the purpose of flight: it should be noted that the pilot should not leave the control when the rotors are turning. For example, the pilot is not allowed to get out of the aircraft in order to welcome passengers and adjust their seat belts with the rotors turning. (c) Rotor engagement for the purpose of maintenance: the implementing rule, however, should not prevent ground runs being conducted by qualified personnel other than pilots for maintenance purposes. The following conditions should be applied: (1) The operator should ensure that the qualification of personnel, other than pilots, who are authorised to conduct maintenance runs is described in the appropriate manual. (2) Ground runs should not include taxiing the helicopter. (3) There should be no passengers on board. Issue 1.00 Page 15 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (4) Maintenance runs should not include collective increase or auto pilot engagement (risk of ground resonance). NCO.GEN.125 Portable electronic devices The pilot-in-command shall not permit any person to use a portable electronic device (PED) on board an aircraft, including an electronic flight bag (EFB), that could adversely affect the performance of the aircraft systems and equipment or the ability of the flight crew member to operate the aircraft. AMC1 NCO.GEN.125 Portable electronic devices (PEDs) ELECTRONIC FLIGHT BAGS (EFBS) — HARDWARE (a) EFB viewable stowage When a viewable stowage device is used, the pilot-in-command should ensure that, if the EFB moves or is separated from its stowage, or if the viewable stowage is unsecured from the aircraft (as a result of turbulence, manoeuvring, or other action), it will not jam flight controls, damage flight deck equipment, or injure any person on board. The viewable stowage device should not be positioned in such a way that it obstructs visual or physical access to aircraft controls and/or displays, flight crew ingress or egress, or external vision. The design of the viewable stowage device should allow the user easy access to any item of the EFB system, and notably to the EFB controls and a clear view of the EFB display while in use. (b) Cables If cables are used to connect an EFB to an aircraft system, power source, or any other equipment: (1) the cables should not hang loosely in a way that compromises task performance and safety; flight crew should be able to easily secure the cables out of the way during operations (e.g. by using cable tether straps); and (2) the cables should be of sufficient length so that they do not to obstruct the use of any movable device on the flight deck. AMC2 NCO.GEN.125 Portable electronic devices (PEDs) ELECTRONIC FLIGHT BAGS (EFBs) — FUNCTIONS (a) Familiarisation The pilot-in-command should familiarise himself or herself with the use of the EFB hardware and its applications on the ground before using them in flight for the first time. A user guide should be available for the pilot-in-command. (b) Check before flight Before each flight, the pilot-in-command should perform the following checks to ensure the continued safe operation of the EFB during the flight: (1) general check of the EFB operation by switching it ON and checking that the applications they intend to use in flight are adequately operative; Issue 1.00 Page 16 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (2) check of the remaining available battery power, if applicable, to ensure the availability of the EFB during the planned flight; (3) check of the version effectivity of the EFB databases, if applicable (e.g. for charts, performance calculation and weight and balance applications); and (4) check that an appropriate backup is available when a chart application or an application displaying aircraft checklists is used. (c) Chart applications The navigation charts that are depicted should contain the necessary information in an appropriate format, to perform the operation safely. Consideration should be given to the size of the display to ensure legibility. (d) Performance calculation and weight and balance functions or applications Prior to the first use of a performance calculation or weight and balance function or application, and following any update of the database supporting the function or the application, a check should be performed on the ground to verify that the output of the application corresponds with the data derived from the AFM (or other appropriate sources); - document.segment-2 Verify source ↗

AI-assisted research summary: This provision requires operators and pilots-in-command to keep key flight and safety documents available, report dangerous goods events, follow CAA safety measures, and meet several operational checks and minima rules.
(e) Airport moving map display (AMMD) application An AMMD application should not be used as a primary means of navigation for taxiing, but as a confirmation of outside visual references. (f) Other functions If advanced functions on non-certified devices that display information related to the aircraft position in flight, navigation, surroundings in terms of e.g. terrain or traffic, or attitude are used, the pilot in command should be aware of the potential misleading or erroneous information displayed and should only use these functions as an advisory or supplementary means. GM1 NCO.GEN.125 Portable electronic devices DEFINITIONS (a) Definition and categories of PEDs PEDs are any kind of electronic device, typically but not limited to consumer electronics, brought on board the aircraft by crew members, passengers, or as part of the cargo and that are not included in the approved aircraft configuration. All equipment that is able to consume electrical energy falls under this definition. The electrical energy can be provided from internal sources as batteries (chargeable or non-rechargeable) or the devices may also be connected to specific aircraft power sources. PEDs include the following two categories: (1) Non-intentional transmitters can non-intentionally radiate RF transmissions, sometimes referred to as spurious emissions. This category includes, but is not limited to, calculators, cameras, radio receivers, audio and video players, electronic games and toys; when these devices are not equipped with a transmitting function. (2) Intentional transmitters radiate RF transmissions on specific frequencies as part of their intended function. In addition, they may radiate non-intentional transmissions like any PED. The term ‘transmitting PED’ (T-PED) is used to identify the transmitting capability of the PED. Intentional transmitters are transmitting devices such as RF-based remote control equipment, Issue 1.00 Page 17 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL which may include some toys, two-way radios (sometimes referred to as private mobile radio), mobile phones of any type, satellite phones, computers with mobile phone data connection, wireless local area network (WLAN) or Bluetooth capability. After deactivation of the transmitting capability, e.g. by activating the so-called ‘flight mode’ or ‘flight safety mode’, the T-PED remains a PED having non-intentional emissions. (b) Definition of the switched-off status Many PEDs are not completely disconnected from the internal power source when switched off. The switching function may leave some remaining functionality e.g. data storage, timer, clock, etc. These devices can be considered switched off when in the deactivated status. The same applies for devices having no transmitting capability and are operated by coin cells without further deactivation capability, e.g. wrist watches. GM2 NCO.GEN.125 Portable electronic devices GENERAL (a) PEDs can pose a risk of interference with electronically operated aircraft systems. Those systems could range from the electronic engine control, instruments, navigation or communication equipment, autopilots to any other type of avionic equipment on the aircraft. The interference can result in on-board systems malfunctioning or providing misleading information and communication disturbance. These can also lead to an increased workload for the flight crew. (b) Interference may be caused by transmitters being part of the PED’s functionality or by unintentional transmissions from the PED. Due to the likely proximity of the PED to any electronically operated aircraft system and the generally limited shielding found in small aircraft, the risk of interference is to be considered higher than that for larger aircraft with metal airframes. (c) During certification of the aircraft, when qualifying the aircraft functions consideration may only have been made of short-term exposure to a high radiating field, with an acceptable mitigating measure being a return to normal function after removal of the threat. This certification assumption may not be true when operating the transmitting PED on board the aircraft. (d) It has been found that compliance with the electromagnetic compatibility (EMC) Directive 2004/108/EC and related European standards, as indicated by the CE marking, is not sufficient to exclude the existence of interference. A well-known interference is the demodulation of the transmitted signal from GSM (global system for mobile communications) mobile phones leading to audio disturbances in other systems. Similar interferences are difficult to predict during the PED design and protecting the aircraft’s electronic systems against the full range of potential interferences is practically impossible. Therefore, not operating PEDs on-board aircraft is the safest option, especially as effects may not be identified immediately but under the most inconvenient circumstances. (e) Guidance to follow in case of fire caused by PEDs is provided by the International Civil Aviation Organisation, ‘Emergency response guidance for aircraft incidents involving dangerous goods’, ICAO Doc 9481-AN/928.

GM1 NCO.GEN.135(a)(13) Documents, manuals and information to be carried DOCUMENTS THAT MAY BE PERTINENT TO THE FLIGHT Any other documents that may be pertinent to the flight or required by the States concerned with the flight may include, for example, forms to comply with reporting requirements. STATES CONCERNED WITH THE FLIGHT The States concerned are those of origin, transit, overflight and destination of the flight. NCO.GEN.140 Transport of dangerous goods (a) The transport of dangerous goods by air shall be conducted in accordance with Annex 18 to the Chicago Convention as last amended and amplified by the Technical Instructions for the Safe Transport of Dangerous Goods by Air (ICAO Doc 9284-AN/905), including its supplements and any other addenda or corrigenda. (b) Dangerous goods shall only be transported by the operator approved in accordance with MCAR- SPA except when: (1) they are not subject to the Technical Instructions in accordance with Part 1 of those Instructions; or (2) they are carried by passengers or the pilot-in-command, or are in baggage, in accordance with Part 8 of the Technical Instructions; (3) they are carried by operators of ELA2 aircraft. (c) The pilot-in-command shall take all reasonable measures to prevent dangerous goods from being carried on board inadvertently. Issue 1.00 Page 21 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (d) The pilot-in-command shall, in accordance with the Technical Instructions, report without delay to the competent authority and the appropriate authority of the State of occurrence in the event of any dangerous goods accidents or incidents. (e) The pilot-in-command shall ensure that passengers are provided with information about dangerous goods in accordance with the Technical Instructions. (f) Reasonable quantities of articles and substances that would otherwise be classified as dangerous goods and that are used to facilitate flight safety, where carriage aboard the aircraft is advisable to ensure their timely availability for operational purposes, shall be considered authorised under paragraph 1;2.2.1(a) of the Technical Instructions. This is regardless of whether or not such articles and substances are required to be carried or intended to be used in connection with a particular flight. The packing and loading on board of the above-mentioned articles and substances shall be performed, under the responsibility of the pilot in command, in such a way as to minimise the risks posed to crew members, passengers, cargo or the aircraft during aircraft operations. GM1 NCO.GEN.140(a) Transport of dangerous goods GENERAL (a) The requirement to transport dangerous goods by air in accordance with the Technical Instructions is irrespective of whether: (1) the flight is wholly or partly within or wholly outside the territory of a State; or (2) an approval to carry dangerous goods in accordance with MCAR-SPA, Subpart G is held. (b) The Technical Instructions provide that in certain circumstances dangerous goods, which are normally forbidden on an aircraft, may be carried. These circumstances include cases of extreme urgency or when other forms of transport are inappropriate or when full compliance with the prescribed requirements is contrary to the public interest. In these circumstances all the States concerned may grant exemptions from the provisions of the Technical Instructions provided that an overall level of safety that is at least equivalent to that provided by the Technical Instructions is achieved. Although exemptions are most likely to be granted for the carriage of dangerous goods that are not permitted in normal circumstances, they may also be granted in other circumstances, such as when the packaging to be used is not provided for by the appropriate packing method or the quantity in the packaging is greater than that permitted. The Technical Instructions also make provision for some dangerous goods to be carried when an approval has been granted only by the State of origin and the competent authority. (c) When an exemption is required, the States concerned are those of origin, transit, overflight and destination of the consignment and that of the operator. For the State of overflight, if none of the criteria for granting an exemption are relevant, an exemption may be granted based solely on whether it is believed that an equivalent level of safety in air transport has been achieved. (d) The Technical Instructions provide that exemptions and approvals are granted by the ‘appropriate national authority’, which is intended to be the authority responsible for the particular aspect against which the exemption or approval is being sought. The operator should ensure that all relevant conditions on an exemption or approval are met. (e) The exemption or approval referred to in (b) to (d) is in addition to the approval required by MCAR- SPA.

The following are applicable changes to the MMEL that require amendment of the MEL: Issue 1.00 Page 26 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (1) a reduction of the rectification interval; (2) change of an item, only when the change is applicable to the aircraft or type of operations and is more restrictive; (3) reduced timescales for the implementation of safety-related amendments may be required by the Agency and/or the CAA. (b) An acceptable timescale for notifying the amended MEL to the CAA is 90 days from the effective date specified in the approved change to the MMEL. (c) In addition to the list of items and related dispatch conditions, the MEL should contain: (1) a preamble, including guidance and definitions for flight crew members and maintenance personnel using the MEL. The MEL preamble should: (i) reflect the content of the MMEL preamble as applicable to the MEL scope and extent; (ii) contain terms and definitions used in the MEL; (iii) contain any other relevant specific information for the MEL scope and use that is not originally provided in the MMEL; (iv) provide guidance on how to identify the origin of a failure or malfunction to the extent necessary for appropriate application of the MEL; (v) provide guidance on the management of multiple unserviceabilities, based on the guidance given in the MMEL; and (vi) provide guidance on placarding of inoperative items to inform crew members of equipment condition as appropriate. In particular, when such items are accessible to the crew during flight, the control(s) and indicator(s) related to inoperative unit(s) should be clearly placarded. (2) the revision status of the MMEL upon which the MEL is based and the revision status of the MEL; (3) the scope, extent and purpose of the MEL; (4) operational and maintenance procedures as part of the MEL or by means of reference to another appropriate document, based on the operational and maintenance procedures referenced in the MMEL; and (5) the dispatch conditions associated with flights conducted in accordance with special approvals held by the operator in accordance with Part-SPA. (d) The operator should: (1) establish rectification intervals for each inoperative instrument, item of equipment or function listed in the MEL. The rectification interval in the MEL should not be less restrictive than the corresponding rectification interval in the MMEL. The definitions and categories of rectification intervals are provided in CS-MMEL as well as in CS-GEN-MMEL; and (2) establish an effective rectification programme. (e) The operator should establish the operational and maintenance procedures referenced in the MEL, taking into account the operational and maintenance procedures referenced in the MMEL. These procedures should be part of the operator’s manuals or the MEL. (f) The operator should amend the operational and maintenance procedures referenced in the MEL after any applicable change to the operational and maintenance procedures referenced in the MMEL. Issue 1.00 Page 27 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL (g) Unless otherwise specified in the MEL, the operator should complete: (1) the operational procedures referenced in the MEL when planning for and/or operating with the listed item inoperative; and (2) the maintenance procedures referenced in the MEL prior to operating with the listed item inoperative. AMC2 NCO.GEN.155 Minimum equipment list FORMAT OF THE MEL The MEL format, the presentation of MEL items and dispatch conditions should: (a) reflect those of the MMEL; (b) follow the ATA 100/2200 Specification numbering system for MEL items; and (c) when different from (a) and (b), be clear and unambiguous. AMC3 NCO.GEN.155 Minimum equipment list EXTENT OF THE MEL The operator should include guidance in the MEL on how to deal with any failures that occur between the commencement of the flight and the start of the take-off. If a failure occurs between the commencement of the flight and the start of the take-off, any decision to continue the flight should be subject to pilot judgement and good airmanship. The pilot-in-command may refer to the MEL before any decision to continue the flight is taken. AMC4 NCO.GEN.155 Minimum equipment list OPERATIONAL AND MAINTENANCE PROCEDURES (a) The operational and maintenance procedures referenced in the MEL should be based on the operational and maintenance procedures referenced in the MMEL. Modified procedures may, however, be developed by the operator when they provide the same level of safety as required by the MMEL. Modified maintenance procedures should be developed in accordance with the applicable airworthiness requirements. (b) Providing appropriate operational and maintenance procedures referenced in the MEL, regardless of who developed them, is the responsibility of the operator. (c) Any item in the MEL requiring an operational or maintenance procedure to ensure an acceptable level of safety should be so identified in the ‘remarks’ or ‘exceptions’ column/part/section of the MEL. This will normally be ‘(O)’ for an operational procedure, or ‘(M)’ for a maintenance procedure. ‘(O)(M)’ means both operational and maintenance procedures are required. (d) The satisfactory accomplishment of all procedures, regardless of who performs them, is the responsibility of the operator. Issue 1.00 Page 28 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL AMC5 NCO.GEN.155 Minimum equipment list OPERATIONAL AND MAINTENANCE PROCEDURES — APPLICABLE CHANGES (a) Changes to the operational and maintenance procedures referenced in the MMEL are considered applicable and require the amendment of the maintenance and operating procedures referenced in the MEL when: (1) the modified procedure is applicable to the operator’s MEL; and (2) the purpose of this change is to improve compliance with the intent of the associated MMEL dispatch condition. (b) An acceptable timescale for the amendments of maintenance and operating procedures, as defined in (a), should be 90 days from the date when the amended procedures referenced in the MMEL are made available. Reduced timescales for the implementation of safety-related amendments may be required if the CAA consider it necessary. GM1 NCO.GEN.155 Minimum equipment list GENERAL (a) The Minimum Equipment List (MEL) is a document that lists the equipment that may be temporarily inoperative, subject to certain conditions, at the commencement of flight. This document is prepared by the operator for their own particular aircraft, taking account of their aircraft configuration and all those individual variables that cannot be addressed at MMEL level, such as operating environment, route structure, geographic location, aerodromes where spare parts and maintenance capabilities are available, etc. (b) The MMEL, as defined in the mandatory part of the operational suitability data established in accordance with MCAR-21, is developed in compliance with CS-MMEL or CS-GEN-MMEL. These Certification Specifications contain, among other, guidance intended to standardise the level of relief granted in MMELs, in particular for items that are subject to operational requirements. If an MMEL established as part of the operational suitability data is not available and items subject to operational requirements are listed in the available MMEL without specific relief or dispatch conditions but only with a reference to the operational requirements, the operator may refer to CS- MMEL or CS-GEN-MMEL guidance material, as applicable, to develop the relevant MEL content for such items. GM2 NCO.GEN.155 Minimum equipment list SCOPE OF THE MEL (a) Examples of special approvals in accordance with MCAR-SPA may be: (1) RVSM (2) LVO (b) When an aircraft has installed equipment which is not required for the operations conducted, the operator may wish to delay rectification of such items for an indefinite period. Such cases are considered to be out of the scope of the MEL, therefore modification of the aircraft is appropriate Issue 1.00 Page 29 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority GENERAL and deactivation, inhibition or removal of the item should be accomplished by an appropriate approved modification procedure. GM3 NCO.GEN.155 Minimum equipment list PURPOSE OF THE MEL The MEL is an alleviating document having the purpose to identify the minimum equipment and conditions to operate safely an aircraft having inoperative equipment. Its purpose is not, however, to encourage the operation of aircraft with inoperative equipment. It is undesirable for aircraft to be dispatched with inoperative equipment and such operations are permitted only as a result of careful analysis of each item to ensure that the acceptable level of safety, as intended in the applicable airworthiness and operational requirements, is maintained. The continued operation of an aircraft in this condition should be minimised. GM4 NCO.GEN.155 Minimum equipment list OPERATIONAL AND MAINTENANCE PROCEDURES (a) Operational and maintenance procedures are an integral part of the compensating conditions needed to maintain an acceptable level of safety, enabling the CAA to approve the MEL. (b) Normally, operational procedures are accomplished by the flight crew; however, other personnel may be qualified and authorised to perform certain functions. (c) Normally, maintenance procedures are accomplished by the maintenance personnel; however, other personnel may be qualified and authorised to perform certain functions in accordance with the applicable airworthiness requirements. (d) Operational and maintenance procedures, regardless of the document where they are contained, should be readily available for use when needed for the application of the MEL. (e) Unless specifically permitted by a maintenance procedure, an inoperative item may not be removed from the aircraft. Issue 1.00 Page 30 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES SUBPART B: OPERATIONAL PROCEDURES NCO.OP.100 Use of aerodromes and operating sites The pilot-in-command shall only use aerodromes and operating sites that are adequate for the type of aircraft and operation concerned. NCO.OP.101 Altimeter check and settings (a) The pilot-in-command shall check the proper operation of the altimeter before each departure. (b) The pilot-in-command shall use appropriate altimeter settings for all phases of flight, taking into account any procedure prescribed by the State of the aerodrome or the State of the airspace. AMC1 NCO.OP.101(a) Altimeter check and settings PRE-FLIGHT ALTIMETER CHECK A serviceable altimeter indicates the elevation of the point selected, plus the height of the altimeter above this point, within a tolerance of ± 60 ft. If the altimeter does not indicate the reference elevation or height exactly but is within the specified tolerances, no adjustment of this indication should be made at any stage of a flight. Also, any error which is within tolerance on the ground should be ignored by the pilot during flight. If no altimeter setting is available at the aerodrome or operating site of departure, the altimeter should be set using the elevation of the aerodrome or operating site, and the altimeter setting should be verified on first contact with an ATS unit. NCO.OP.105 INTENTIONALLY LEFT BLANK NCO.OP.110 Aerodrome operating minima — aeroplanes and helicopters (a) For instrument flight rules (IFR) flights, the pilot-in-command shall establish aerodrome operating minima for each departure, destination or alternate aerodrome that is planned to be used in order to ensure separation of the aircraft from terrain and obstacles and to mitigate the risk of loss of visual references during the visual flight segment of instrument approach operations. (b) The aerodrome operating minima shall take the following elements into account, if relevant: (1) the type, performance, and handling characteristics of the aircraft; (2) the equipment available on the aircraft for the purpose of navigation, acquisition of visual references, and/or control of the flight path during take-off, approach, landing, and missed approach; Issue 1.00 Page 31 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (3) any conditions or limitations stated in the aircraft flight manual (AFM); (4) the dimensions and characteristics of the runways/final approach and take-off areas (FATOs) that may be selected for use; (5) the adequacy and performance of the available visual and non-visual aids and infrastructure; (6) the obstacle clearance altitude/height (OCA/H) for the instrument approach procedures (IAPs), if established; (7) the obstacles in the climb-out areas and clearance margins; (8) the competence and relevant operational experience of the pilot-in-command; (9) the IAP, if established; (10) the aerodrome characteristics and the type of air navigation services (ANS) available, if any; (11) any minima that may be promulgated by the State of the aerodrome; (12) the conditions prescribed in any specific approvals for low-visibility operations (LVOs) or operations with operational credits.; AMC1 NCO.OP.110 Aerodrome operating minima — aeroplanes and helicopters TAKE-OFF OPERATIONS (a) General Take-off minima should be expressed as visibility (VIS) or runway visual range (RVR) limits, taking into account all relevant factors for each runway/final approach and take-off area (FATO)/operating site planned to be used and aircraft characteristics and equipment. Where there is a specific need to see and avoid obstacles on departure and/or for a forced landing, additional conditions, e.g. ceiling, it should be specified. (b) Visual reference (1) The take-off minima should be selected to ensure sufficient guidance to control the aircraft in the event of both a rejected take-off in adverse circumstances and an engine failure after rotation. (2) For night operations, sufficient lighting should be in operation to illuminate the runway/final approach and take-off area (FATO) and any relevant obstacles. (3) For point-in-space (PinS) departures to an initial departure fix (IDF), the take-off minima should be selected to ensure sufficient guidance to see and avoid obstacles and return to the heliport if the flight cannot be continued visually to the IDF. The minimum VIS should be 800 m and the minimum ceiling should be 250 ft. (4) For helicopters outside of a runway environment, the minimum VIS should be 800 m, and for offshore helideck operations, the minimum VIS should be 500 m.

GM1 NCO.OP.110 Aerodrome operating minima — aeroplanes and helicopters AIRCRAFT CATEGORIES (a) Aircraft categories should be based on the indicated airspeed at threshold (V ), which is equal to AT the stalling speed (V ) multiplied by 1.3 or where published 1-g (gravity) stall speed (V ) multiplied SO S1g Issue 1.00 Page 35 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES by 1.23 in the landing configuration at the maximum certified landing mass. If both V and V are SO S1g available, the higher resulting V should be used. AT (b) The aircraft categories specified in Table 7 should be used. Table 7: Aircraft categories corresponding to VAT values Aircraft category V AT A Less than 91 kt B from 91 to 120 kt C from 121 to 140 kt D from 141 to 165 kt E from 166 to 210 kt (c) Helicopters are also eligible for Category H where applicable. GM2 NCO.OP.110 Aerodrome operating minima — aeroplanes and helicopters FLIGHTS WITH VFR AND IFR SEGMENTS Where a flight contains VFR and IFR segments, aerodrome operating minima need be established only as far as relevant to the IFR segments. Attention is drawn to NCO.OP.160 (a) and (c), according to which, the pilot-in-command shall be satisfied that the VFR segments will be conducted in conditions at or above the applicable VFR operating minima. For example, for a VFR departure changing to IFR at a transition point en-route and an IFR arrival at destination, the pilot-in-command should be satisfied that VMC will exist up to the transition point, and aerodrome operating minima should be established for the destination and any alternate destinations required. GM3 NCO.OP.110 Aerodrome operating minima — aeroplanes and helicopters MEANS TO DETERMINE THE REQUIRED RVR BASED ON DH AND LIGHTING FACILITIES (a) The values in Table 2 are derived from the formula below: RVR (m) = [(DH/MDH (ft) x 0.3048)/tanα] — length of approach lights (m), where α is the calculation angle, being a default value of 3.00° increasing in steps of 0.10° for each line in Table 2 up to 3.77° and then remaining constant. An upper RVR limit of 2 400 m has been applied to the table. (b) The lighting system classes in Table 2 have the meaning specified in Table 6. GM4 NCO.OP.110 Aerodrome operating minima — aeroplanes and helicopters USE OF THIRD-PARTY INFORMATION If a pilot-in-command uses information provided by a third party for aerodrome operating minima, the pilot-in-command verifies that the method for calculating minima is in accordance with this Regulation.

For example, if components of a FALS have failed leaving only the last 250 m operating normally, the lighting facilities should be treated as BALS. (b) Failures of standby equipment, standby power systems, middle markers and RVR assessment systems have no effect on minima.

When this information is not available (e.g. not mentioned in the AIP, etc.), then the pilot should take into account Table 8 or 9 below, as applicable, when determining the DH/MDH: Table 8 Runway type minima — aeroplanes Runway type Lowest DH/MDH (ft) PA runway, category I 200 NPA runway 250 Non-instrument runway Circling minima as shown in Table 1 in NCC.OP.112 Table 9 Type of runway/FATO minima — helicopters Type of runway/FATO Lowest DH/MDH (ft) PA runway, category I 200 NPA runway Non-instrument runway Instrument FATO 200 FATO 250 Table 8 does not apply to helicopter PinS approaches with instructions to ‘proceed VFR’. GM1 NCO.OP.111 Aerodrome operating minima — 2D and 3D approach operations APPROACH OPERATIONS — VERTICAL PATH CONTROL FOR NPA Issue 1.00 Page 38 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (a) During a 3D instrument approach operation (using both lateral and vertical navigation guidance), the displayed vertical path should be followed continuously. The approach may be continued to DA/H, at which point a missed approach must be initiated if visual reference is not acquired. (b) During a 2D instrument approach operation (using lateral navigation guidance only) flown using the continuous descent final approach (CDFA) technique, the vertical path should be approximated continuously by: (1) choosing an appropriate vertical speed; (2) cross-checking level against position along the approach; and (3) adapting the vertical speed as required. The approach may be continued to DA/H or the missed approach point (MAPt) (whichever is reached first), at which point a missed approach must be initiated if visual reference is not acquired. There is no MDH for an NPA flown using the CDFA technique. An aircraft may descend briefly below the DH on an NPA flown using the CDFA technique, in the same way as it may on a PA or APV. (c) During a 2D instrument approach operation (using lateral navigation guidance only) flown using the step-down (non-CDFA) technique, the vertical path consists of a sequence of one or more descents to the next published level (i.e. the MDA/H or height at the next stepdown fix). The aircraft may fly level at the MDA/H until reaching the MAPt, where a missed approach must be initiated if visual reference is not acquired. The CDFA technique has substantially improved safety performance in commercial air transport operations with complex motor-powered aircraft. In lighter, more manoeuvrable aircraft, operated by a single pilot, which may be accustomed to shorter and steeper visual approaches, there may sometimes be advantages to a step-down technique. Due consideration should be given to the choice of vertical path control at the planning stage of flight. GM2 NCO.OP.111 Aerodrome operating minima — 2D and 3D approach operations DH/MDH — CALCULATION OF DA/MDA NCO.OP.111 refers to DH and MDH because the rule compares heights with other heights (system minima, minimum DH in the AFM, etc.). Usually, the DH or MDH will be converted to DA or MDA for operational use by adding the threshold elevation. GM3 NCO.OP.111 Aerodrome operating minima — 2D and 3D approach operations DH/MDH — PinS APPROACHES WITH VIRTUAL DESTINATION For PinS approaches with instructions to ‘proceed VFR’ that are not associated with a runway/FATO/operating site, DH/MDH can be established with reference to the ground below the MAPt.

(c) Instrument approach followed by visual manoeuvring (circling) without prescribed tracks: (1) When the aeroplane is on the initial instrument approach, before visual reference is established, but not below MDA/H — the aeroplane should follow the corresponding instrument approach procedure (IAP) until the appropriate instrument MAPt is reached. (2) At the beginning of the level flight phase at or above the MDA/H, the instrument approach track should be maintained until the pilot: (i) estimates that, in all probability, visual contact with the runway of intended landing or the runway environment will be maintained during the entire circling procedure; (ii) estimates that the aeroplane is within the circling area before commencing circling; and (iii) is able to determine the aeroplane’s position in relation to the runway of intended landing with the aid of the appropriate visual references. (3) When reaching the published instrument MAPt and the conditions stipulated in (c)(2) are unable to be established by the pilot, a missed approach should be carried out in accordance with that instrument approach procedure. (4) After the aeroplane has left the track of the initial instrument approach, the flight phase outbound from the runway should be limited to an appropriate distance, which is required to align the aeroplane onto the final approach. Such manoeuvres should be conducted to enable the aeroplane: Issue 1.00 Page 40 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (i) to attain a controlled and stable descent path to the intended landing runway; and (ii) to remain within the circling area and in such a way that visual contact with the runway of intended landing or runway environment is maintained at all times. (5) Flight manoeuvres should be carried out at an altitude/height that is not less than the circling MDA/H. (6) Descent below MDA/H should not be initiated until the threshold of the runway to be used has been appropriately identified. The aeroplane should be in a position to continue with a normal rate of descent and land within the touchdown zone. (d) Instrument approach followed by a visual manoeuvring (circling) with prescribed track: (1) The aeroplane should remain on the initial instrument approach procedure until one of the following is reached: (i) the prescribed divergence point to commence circling on the prescribed track; or (ii) the MAPt. (2) The aeroplane should be established on the instrument approach track determined by the radio navigation aids, RNAV, RNP, or ILS, MLS or GLS in level flight at or above the MDA/H at or by the circling manoeuvre divergence point. (3) If the divergence point is reached before the required visual reference is acquired, a missed approach should be initiated not later than the MAPt and completed in accordance with the initial instrument approach procedure. (4) When commencing the prescribed circling manoeuvre at the published divergence point, the subsequent manoeuvres should be conducted to comply with the published routing and published heights/altitudes. (5) Unless otherwise specified, once the aeroplane is established on the prescribed track(s), the published visual reference does not need to be maintained unless: (i) required by the State of the aerodrome; or (ii) the circling MAPt (if published) is reached. (6) If the prescribed circling manoeuvre has a published MAPt and the required visual reference has not been obtained by that point, a missed approach should be executed in accordance with (e)(2) and (e)(3). (7) Subsequent further descent below MDA/H should only commence when the required visual reference has been obtained. (8) Unless otherwise specified in the procedure, final descent should not be commenced from MDA/H until the threshold of the intended landing runway has been identified and the aeroplane is in a position to continue with a normal rate of descent to land within the touchdown zone. (e) Missed approach: (1) Missed approach during the instrument procedure prior to circling: (i) if the missed approach is required to be flown when the aeroplane is positioned on the instrument approach track defined by radio navigation aids, RNAV, RNP or ILS, MLS or GLS and before commencing the circling manoeuvre, the published missed approach for the instrument approach should be followed; or Issue 1.00 Page 41 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (ii) if the instrument approach procedure is carried out with the aid of an ILS, MLS or a stabilised approach (SAp), the MAPt associated with an ILS or MLS procedure without glide path (GP-out procedure) or the SAp, where applicable, should be used. (2) If a prescribed missed approach is published for the circling manoeuvre, this overrides the manoeuvres prescribed below. (3) If visual reference is lost while circling to land after the aeroplane has departed from the initial instrument approach track, the missed approach specified for that particular instrument approach should be followed. It is expected that the pilot will make an initial climbing turn toward the intended landing runway to a position overhead of the aerodrome where the pilot will establish the aeroplane in a climb on the instrument missed approach segment. (4) The aeroplane should not leave the visual manoeuvring (circling) area, which is obstacle protected, unless: (i) established on the appropriate missed approach procedure; or (ii) at minimum sector altitude (MSA). (5) All turns should be made in the same direction and the aeroplane should remain within the circling protected area while climbing either: (i) to the altitude assigned to any published circling missed approach manoeuvre if applicable; (ii) to the altitude assigned to the missed approach of the initial instrument approach; (iii) to the MSA; (iv) to the minimum holding altitude (MHA) applicable for transition to a holding facility or fix, or continue to climb to an MSA; or (v) as directed by ATS. When the missed approach procedure is commenced on the ‘downwind’ leg of the circling manoeuvre, an ‘S’ turn may be undertaken to align the aeroplane on the initial instrument approach missed approach path, provided the aeroplane remains within the protected circling area. The pilot-in-command should be responsible for ensuring adequate terrain clearance during the above-stipulated manoeuvres, particularly during the execution of a missed approach initiated by ATS. (6) Because the circling manoeuvre may be accomplished in more than one direction, different patterns will be required to establish the aeroplane on the prescribed missed approach course, depending on its position at the time visual reference is lost. In particular, all turns are to be in the prescribed direction if this is restricted, e.g. to the west/east (left or right hand) to remain within the protected circling area. (7) If a missed approach procedure is published for a particular runway onto which the aeroplane is conducting a circling approach and the aeroplane has commenced a manoeuvre to align with the runway, the missed approach for this direction may be accomplished. The ATS unit should be informed of the intention to fly the published missed approach procedure for that particular runway. (8) The pilot-in-command should advise ATS when any missed approach procedure has been commenced, the height/altitude the aeroplane is climbing to and the position the aeroplane is proceeding towards and/or heading the aeroplane is established on. Issue 1.00 Page 42 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES GM2 NCO.OP.112 Aerodrome operating minima — circling operations with aeroplanes DH/MDH — CALCULATION OF DA/MDA MCAR Air operations PART-NCO.OP.111 refers to MDH because the rule compares heights with other heights (minimum circling height, OCH, etc.). Usually, the MDH will be converted to MDA for operational use by adding the aerodrome elevation. NCO.OP.113 Aerodrome operating minima – onshore circling operations with helicopters The MDH for an onshore circling operation with helicopters shall not be lower than 250 ft and the meteorological visibility not less than 800 m. NCO.OP.115 Departure and approach procedures – aeroplanes and helicopters (a) The pilot-in-command shall use the departure and approach procedures established by the State of the aerodrome, if such procedures have been published for the runway or FATO to be used. (b) The pilot-in-command may deviate from a published departure route, arrival route or approach procedure: (1) provided obstacle clearance criteria can be observed, full account is taken of the operating conditions and any ATC clearance is adhered to; or (2) when being radar-vectored by an ATC unit. AMC1 NCO.OP.115 Departure and approach procedures — aeroplanes and helicopters ARRIVALS AND DEPARTURES UNDER IFR WHERE NO INSTRUMENT FLIGHT PROCEDURES ARE PUBLISHED When arriving or departing under IFR to/from an aerodrome or operating site with no published instrument flight procedure, the pilot-in-command should ensure that sufficient obstacle clearance is available for safe operation. This may be achieved, for example, by climbing or descending visually when below a minimum altitude at which obstacle clearance is known to exist. When operating IFR in uncontrolled airspace, separation from other aircraft remains the responsibility of the pilot-in-command. The pilot-in-command should also comply with any flight planning and communication requirements designated by the CAA under SERA.4001(b)(3) and SERA.5025(b). Any ATC clearance required to enter controlled airspace must be obtained prior to entry. NCO.OP.116 Performance-based navigation – aeroplanes and helicopters The pilot-in-command shall ensure that, when PBN is required for the route or procedure to be flown: (a) the relevant PBN navigation specification is stated in the AFM or other document that has been approved by the certifying authority as part of an airworthiness assessment or is based on such approval; and Issue 1.00 Page 43 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (b) the aircraft is operated in conformance with the relevant navigation specification and limitations in the AFM or other document mentioned above. AMC1 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters PBN OPERATIONS For operations where a navigation specification for performance-based navigation (PBN) has been prescribed and no specific approval is required in accordance with SPA.PBN.100, the pilot-in-command should: (a) use operating procedures specifying: (1) normal, abnormal and contingency procedures; (2) electronic navigation database management; and (3) relevant entries in the minimum equipment list (MEL), where applicable; (b) ensure that he/she is appropriately trained for the intended operation. AMC2 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters MONITORING AND VERIFICATION (a) Preflight and general considerations (1) At navigation system initialisation, the pilot-in-command should confirm that the navigation database is current and verify that the aircraft position, if required, has been entered correctly. (2) The active flight plan, if applicable, should be checked by comparing the charts or other applicable documents with navigation equipment and displays. This includes confirmation of the waypoint sequence, reasonableness of track angles and distances, any altitude or speed constraints, and, where possible, which waypoints are fly-by and which are fly-over. Where relevant, the RF leg arc radii should be confirmed. (3) The pilot-in-command should check that the navigation aids critical to the operation of the intended PBN procedure are available. (4) The pilot-in-command should confirm the navigation aids that should be excluded from the operation, if any. (5) An arrival, approach or departure procedure should not be used if the validity of the procedure in the navigation database has expired. (b) Departure (1) Prior to commencing a take-off on a PBN procedure, the pilot-in-command should verify that the area navigation system is available and operating correctly and the correct aerodrome and runway data has been loaded. A positive check should be made that the indicated aircraft position is consistent with the actual aircraft position at the start of the take-off roll (aeroplanes) or lift-off (helicopters). (2) Where GNSS is used, the signal should be acquired before the take-off roll (aeroplanes) or lift- off (helicopters) commences. Issue 1.00 Page 44 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (3) Unless automatic updating of the actual departure point is provided, the pilot-in-command should ensure initialisation on the runway or FATO either by means of a manual runway threshold or intersection update, as applicable. This is to preclude any inappropriate or inadvertent position shift after take-off. (c) Arrival and approach (1) The pilot-in-command should verify that the navigation system is operating correctly and the correct arrival procedure and runway (including any applicable transition) are entered and properly depicted. (2) Any published altitude and speed constraints should be observed. (3) The pilot-in-command should check approach procedures (including alternate aerodromes if needed) as extracted by the system (e.g. CDU flight plan page) or presented graphically on the moving map, in order to confirm the correct loading and the reasonableness of the procedure content. (4) Prior to commencing the approach operation (before the IAF), the pilot-in-command should verify the correctness of the loaded procedure by comparison with the appropriate approach charts. This check should include: (i) the waypoint sequence; (ii) reasonableness of the tracks and distances of the approach legs and the accuracy of the inbound course; and (iii) the vertical path angle, if applicable. (d) Altimetry settings for RNP APCH operations using Baro VNAV (1) Barometric settings (i) The pilot-in-command should set and confirm the correct altimeter setting and check that the two altimeters provide altitude values that do not differ more than 100 ft at the most at or before the FAF. (ii) The pilot-in-command should fly the procedure with: (A) a current local altimeter setting source available — a remote or regional altimeter setting source should not be used; and (B) the QNH/QFE, as appropriate, set on the aircraft’s altimeters. (2) Temperature compensation (i) For RNP APCH operations to LNAV/VNAV minima using Baro VNAV: (A) the pilot-in-command should not commence the approach when the aerodrome temperature is outside the promulgated aerodrome temperature limits for the procedure, unless the area navigation system is equipped with approved temperature compensation for the final approach; (B) when the temperature is within promulgated limits, the pilot-in-command should not make compensation to the altitude at the FAF; and (C) since only the final approach segment is protected by the promulgated aerodrome temperature limits, the pilot-in-command should consider the effect of temperature on terrain and obstacle clearance in other phases of flight. (ii) For RNP APCH operations to LNAV minima using Baro VNAV: Issue 1.00 Page 45 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (A) the pilot-in-command should consider the effect of temperature on terrain and obstacle clearance in all phases of flight, in particular on any step-down fix; (B) if the temperature is outside promulgated limits for RNP APCH to LNAV/VNAV minima, the pilot-in-command should not use a Baro VNAV function for vertical guidance, unless the area navigation system is equipped with approved temperature compensation for the final approach. (e) Sensor and lateral navigation accuracy selection (1) For multi-sensor systems, the pilot-in-command should verify, during the approach, that the GNSS sensor is used for position computation. (2) For aircraft with RNP input selection capability, the pilot-in-command should confirm that the indicated RNP value is appropriate for the PBN operation. AMC3 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters MANAGAMENT OF THE NAVIGATION DATABASE (a) For RNAV 1, RNAV 2, RNP 1, RNP 2, and RNP APCH, the pilot-in-command should neither insert nor modify waypoints by manual entry into a procedure (departure, arrival or approach) that has been retrieved from the database. User-defined data may be entered and used for waypoint altitude/speed constraints on a procedure where said constraints are not included in the navigation database coding. (b) For RNP 4 operations, the pilot-in-command should not modify waypoints that have been retrieved from the database. User-defined data (e.g. for flex-track routes) may be entered and used. (c) The lateral and vertical definition of the flight path between the FAF and the missed approach point (MAPt) retrieved from the database should not be revised by the pilot-in-command. AMC4 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters DISPLAYS AND AUTOMATION (a) For RNAV 1, RNP 1, and RNP APCH operations, the pilot-in-command should use a lateral deviation indicator, and where available, flight director and/or autopilot in lateral navigation mode. (b) The appropriate displays should be selected so that the following information can be monitored: (1) the computed desired path; (2) aircraft position relative to the lateral path (cross-track deviation) for FTE monitoring; and (3) aircraft position relative to the vertical path (for a 3D operation). (c) The pilot-in-command of an aircraft with a lateral deviation indicator (e.g. CDI) should ensure that lateral deviation indicator scaling (full-scale deflection) is suitable for the navigation accuracy associated with the various segments of the procedure. (d) The pilot-in-command should maintain procedure centrelines unless authorised to deviate by ATC or demanded by emergency conditions. (e) Cross-track error/deviation (the difference between the area-navigation-system-computed path and the aircraft-computed position) should normally be limited to ± ½ time the RNAV/RNP value Issue 1.00 Page 46 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES associated with the procedure. Brief deviations from this standard (e.g. overshoots or undershoots during and immediately after turns) up to a maximum of 1 time the RNAV/RNP value should be allowable. (f) For a 3D approach operation, the pilot-in-command should use a vertical deviation indicator and, where required by AFM/POH limitations, a flight director or autopilot in vertical navigation mode. (g) Deviations below the vertical path should not exceed 75 ft at any time, or half-scale deflection where angular deviation is indicated, and not more than 75 ft above the vertical profile, or half-scale deflection where angular deviation is indicated, at or below 1 000 ft above aerodrome level. The pilot-in-command should execute a missed approach if the vertical deviation exceeds this criterion, unless the pilot-in-command has in sight the visual references required to continue the approach. AMC5 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters VECTORING AND POSITIONING (a) ATC tactical interventions in the terminal area may include radar headings, ‘direct to’ clearances which bypass the initial legs of an approach procedure, interceptions of an initial or intermediate segments of an approach procedure or the insertion of additional waypoints loaded from the database. (b) In complying with ATC instructions, the pilot-in-command should be aware of the implications for the navigation system. (c) ‘Direct to’ clearances may be accepted to the IF provided that it is clear to the pilot-in-command that the aircraft will be established on the final approach track at least 2 NM before the FAF. (d) ‘Direct to’ clearance to the FAF should not be acceptable. Modifying the procedure to intercept the final approach track prior to the FAF should be acceptable for radar-vectored arrivals or otherwise only with ATC approval. (e) The final approach trajectory should be intercepted no later than the FAF in order for the aircraft to be correctly established on the final approach track before starting the descent (to ensure terrain and obstacle clearance). (f) ‘Direct to’ clearances to a fix that immediately precede an RF leg should not be permitted. (g) For parallel offset operations en route in RNP 4 and A-RNP, transitions to and from the offset track should maintain an intercept angle of no more than 45° unless specified otherwise by ATC. AMC6 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters ALERTING AND ABORT (a) Unless the pilot-in-command has sufficient visual reference to continue the approach operation to a safe landing, an RNP APCH operation should be discontinued if: (1) navigation system failure is annunciated (e.g. warning flag); (2) lateral or vertical deviations exceed the tolerances; and (3) loss of the on-board monitoring and alerting system. Issue 1.00 Page 47 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (b) Discontinuing the approach operation may not be necessary for a multi-sensor navigation system that includes demonstrated RNP capability without GNSS in accordance with the AFM/POH. (c) Where vertical guidance is lost while the aircraft is still above 1 000 ft AGL, the pilot-in-command may decide to continue the approach to LNAV minima, when supported by the navigation system. AMC7 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters CONTINGENCY PROCEDURES (a) The pilot-in-command should make the necessary preparation to revert to a conventional arrival procedure where appropriate. The following conditions should be considered: (1) failure of the navigation system components including navigation sensors, and a failure effecting flight technical error (e.g. failures of the flight director or autopilot); (2) multiple system failures affecting aircraft performance; (3) coasting on inertial sensors beyond a specified time limit; and (4) RAIM (or equivalent) alert or loss of integrity function. (b) In the event of loss of PBN capability, the pilot-in-command should invoke contingency procedures and navigate using an alternative means of navigation. (c) The pilot-in-command should notify ATC of any problem with PBN capability. (d) In the event of communication failure, the pilot-in-command should continue with the operation in accordance with published lost communication procedures. AMC8 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters RNAV 10 (a) Operating procedures and routes should take account of the RNAV 10 time limit declared for the inertial system, if applicable, considering also the effect of weather conditions that could affect flight duration in RNAV 10 airspace. (b) The operator may extend RNAV 10 inertial navigation time by position updating. The operator should calculate, using statistically-based typical wind scenarios for each planned route, points at which updates can be made, and the points at which further updates will not be possible. GM1 NCO.OP.116 Performance-based navigation – aeroplanes and helicopters DESCRIPTION (a) For both, RNP X and RNAV X designations, the ‘X’ (where stated) refers to the lateral navigation accuracy (total system error) in NM, which is expected to be achieved at least 95 % of the flight time by the population of aircraft operating within the airspace, route or procedure. For RNP APCH and A-RNP, the lateral navigation accuracy depends on the segment. (b) PBN may be required on notified routes, for notified procedures and in notified airspace. RNAV 10 Issue 1.00 Page 48 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (c) For purposes of consistency with the PBN concept, this Regulation is using the designation ‘RNAV 10’ because this specification does not include on-board performance monitoring and alerting. (d) However, it should be noted that many routes still use the designation ‘RNP 10’ instead of ‘RNAV 10’. ‘RNP 10’ was used as designation before the publication of the fourth edition of ICAO Doc 9613 in 2013. The terms ‘RNP 10’ and ‘RNAV 10’ should be considered equivalent. NCO.OP.120 Noise abatement procedures – aeroplanes and helicopters The pilot-in-command shall take into account published noise abatement procedures to minimise the effect of aircraft noise while ensuring that safety has priority over noise abatement. NCO.OP.125 Fuel/energy and oil supply – aeroplanes and helicopters (a) The pilot-in-command shall ensure that the quantity of fuel/energy and oil that is carried on board is sufficient, taking into account the meteorological conditions, any element affecting the performance of the aircraft, any delays that are expected in flight, and any contingencies that may reasonably be expected to affect the flight. (b) The pilot-in-command shall plan a quantity of fuel/energy to be protected as final reserve fuel/energy to ensure a safe landing. The pilot-in-command shall take into account all of the following, and in the following order of priority, to determine the quantity of the final reserve fuel/energy: (1) the severity of the hazard to persons or property that may result from an emergency landing after fuel/energy starvation; and (2) the likelihood of unexpected circumstances that the final reserve fuel/energy may no longer be protected. (c) The pilot-in-command shall commence a flight only if the aircraft carries sufficient fuel/energy and oil: (1) when no destination alternate is required, to fly to the aerodrome or operating site of intended landing, plus the final reserve fuel/energy; or (2) when a destination alternate is required, to fly to the aerodrome or operating site of intended landing, and thereafter, to an alternate aerodrome, plus the final reserve fuel/energy. AMC1 NCO.OP.125(b) Fuel/energy and oil supply — aeroplanes and helicopters PLANNING CRITERIA — FINAL RESERVE FUEL/ENERGY The final reserve fuel (FRF)/energy should be no less than the required fuel/energy to fly: (a) for aeroplanes: (1) for 10 minutes at maximum continuous cruise power at 1 500 ft (450 m) above the destination under VFR by day, taking off and landing at the same aerodrome/landing site, and always remaining within sight of that aerodrome/landing site; (2) for 30 minutes at holding speed at 1 500 ft (450 m) above the destination under VFR by day; and Issue 1.00 Page 49 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (3) for 45 minutes at holding speed at 1 500 ft (450 m) above the destination or destination alternate aerodrome under VFR flights by night and IFR; and (b) for helicopters: (1) for 10 minutes at best-range speed under VFR by day, taking off and landing at the same aerodrome/landing site, and always remaining within 25 NM of that aerodrome/landing site, when needed for the purpose of specialised operations; (2) for 20 minutes at best-range speed for other VFR flights; and (3) for 30 minutes at holding speed at 1 500 ft (450 m) above the destination or destination alternate aerodrome under IFR. AMC2 NCO.OP.125(b) Fuel/energy and oil supply — aeroplanes and helicopters FINAL RESERVE FUEL/ENERGY The quantity of the FRF/energy should be planned before flight and be an easily recalled figure against which the pilot-in-command can assess the current fuel/energy state of the aircraft. AMC3 NCO.OP.125(b) Fuel/energy and oil supply — aeroplanes and helicopters FINAL RESERVE FUEL/ENERGY PROTECTION The planned FRF/energy should be protected as a reserve in normal operations. If the fuel/energy on board falls below the FRF/energy, the pilot-in-command should consider this to be an emergency. The FRF/energy should not be used as contingency fuel in normal operations. When the FRF/energy can no longer be protected, then a fuel/energy emergency should be declared and any landing option explored, including deviating from rules, operational procedures, and methods in the interest of safety (as per point CAT.GEN.MPA.105(b)). GM1 NCO.OP.125(b) Fuel/energy and oil supply — aeroplanes and helicopters LIKELIHOOD OF UNEXPECTED CIRCUMSTANCES TO INCREASE WITH FLIGHT DURATION The likelihood of unexpected circumstances arising after the aircraft is fuelled may increase with the duration of the planned flight (for example, during a long flight, a problem at the destination aerodrome or operating site is more likely to have occurred than during a short local flight). GM2 NCO.OP.125(b) Fuel/energy and oil supply — aeroplanes and helicopters PLANNING of FUEL/ENERGY QUANTITY — HOLDING When planning the fuel/energy quantity, in case of holding, and if the aircraft documentation does not provide approved data for the holding regime, the pilot should derive the fuel/energy flow data from the long-range/best-range cruise data or, if this is not provided, from the lowest available cruise data in power setting tables. Issue 1.00 Page 50 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES NCO.OP.130 Passenger briefing The pilot-in-command shall ensure that before or, where appropriate, during the flight, passengers are given a briefing on emergency equipment and procedures. AMC1 NCO.OP.130 Passenger briefing GENERAL (a) The briefing should include the locations and use of seat belts and if applicable: (1) emergency exits; (2) passenger emergency briefing cards; (3) life-jackets; (4) oxygen dispensing equipment; (5) life rafts; and (6) other emergency equipment provided for individual passenger use. (b) The briefing should also include the location and general manner of use of the principal emergency equipment carried for collective use. NCO.OP.135 Flight preparation (a) Before commencing a flight, the pilot-in-command shall ascertain by every reasonable means available that the space-based facilities, ground and/or water facilities, including communication facilities and navigation aids available and directly required on such flight, for the safe operation of the aircraft, are adequate for the type of operation under which the flight is to be conducted. (b) Before commencing a flight, the pilot-in-command shall be familiar with all available meteorological information appropriate to the intended flight. Preparation for a flight away from the vicinity of the place of departure, and for every flight under IFR, shall include: (1) a study of the available current meteorological reports and forecasts; and (2) the planning of an alternative course of action to provide for the eventuality that the flight cannot be completed as planned, because of meteorological conditions. AMC1 NCO.OP.135(a) Flight preparation ADEQUACY OF GROUND FACILITIES (a) The pilot-in-command, in ascertaining the adequacy of facilities and services available at an aerodrome of intended operation, should assess the safety risk that is associated with the type of the operation in relation to the availability of rescue and fire-fighting services (RFFS). Issue 1.00 Page 51 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (b) The safety risk assessment may conclude that there is no need for availability of RFFS at the aerodrome of intended landing because of the low risk that is associated with the type of aircraft and type of operation specific to NCO. NCO.OP.140 Destination alternate aerodromes — aeroplanes For IFR flights, the pilot-in-command shall specify at least one destination alternate aerodrome in the flight plan, unless the available current meteorological information for the destination indicates, for the period from 1 hour before until 1 hour after the estimated time of arrival, or from the actual time of departure to 1 hour after the estimated time of arrival, whichever is the shorter period, a ceiling of at least 1 000ft above the DH/MDH for an available instrument approach procedure (IAP) and a visibility of at least 5 000m. NCO.OP.141 Destination alternate aerodromes — helicopters For IFR flights, the pilot-in-command shall specify at least one destination alternate aerodrome in the flight plan, unless the available current meteorological information for the destination indicates, for the period from 1 hour before until 1 hour after the estimated time of arrival, or from the actual time of departure to 1 hour after the estimated time of arrival, whichever is the shorter period, a ceiling of at least 1 000ft above the DH/MDH for an available IAP and a visibility of at least 3 000m. NCO.OP.142 Destination alternate aerodromes — instrument approach operations The pilot-in-command shall only select an aerodrome as a destination alternate aerodrome if either: (a) an IAP that does not rely on GNSS is available either at the destination aerodrome or at a destination alternate aerodrome, or (b) all of the following conditions are met: (1) the onboard GNSS equipment is SBAS-capable; (2) the destination aerodrome, any destination alternate aerodrome, and the route between them are within SBAS service area; (3) ABAS is predicted to be available in the event of the unexpected unavailability of SBAS; (4) an IAP is selected (either at destination or destination alternate aerodrome) that does not rely on the availability of SBAS; (5) an appropriate contingency action allows the flight to be completed safely in the event of unavailability of GNSS. AMC1 NCO.OP.142(b)(1) Destination alternate aerodromes — instrument approach operations SBAS-CAPABLE GNSS EQUIPMENT GNSS system which are authorised under (E)TSO-C145 or (E)TSO-C146 or later revisions are SBAS-capable. Aircraft certified for RNP APCH to LPV minima are considered compliant. Issue 1.00 Page 52 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES AMC2 NCO.OP.142(b)(3) Destination alternate aerodromes — instrument approach operations USE OF RAIM FOR SBAS Where a receiver with RAIM is used to meet the requirement for SBAS, its availability should be predicted by a pre-flight RAIM check, in accordance with AMC1 NCO.GEN.105(c). GM1 NCO.OP.142(b)(4) Destination alternate aerodromes — instrument approach operations IAPs THAT DO NOT RELY ON SBAS This instrument approach can be an RNP APCH to LNAV minima. It can also be an RNP APCH to LNAV/VNAV minima using Baro VNAV if the aircraft is equipped with a Baro VNAV function certified for APV. This requirement is only used for planning purposes to cover the possibility of an SBAS loss; it does not prevent the pilot from flying an approach relying on SBAS if SBAS is available. AMC1 NCO.OP.142(b)(5) Destination alternate aerodromes — instrument approach operations APPROPRIATE CONTINGENCY ACTION An appropriate contingency action is an alternative offered in NCO.OP.142(b)(5) to completion of the planned flight to a safe landing, either at the planned destination or a destination alternate, using normal procedures and using navigation equipment meeting the requirements of NCO.IDE.A/H.100, installed for redundancy or as a backup. The contingency action should be considered before flight and take into account the information identified by flight preparation according to NCO.OP.135. It may depend on the flight and availability of navigation solutions (satellites, ground navaids, etc.) and weather conditions (IMC, VMC) along the flight. The contingency action addresses partial loss of navigation capability, such as: loss of the stand-alone GNSS equipment; local loss of GNSS signal-in-space (e.g. local jamming at destination); loss of GNSS signal-in-space. It should take into account what options remain in case of loss of GNSS signal; for instance, (non-GNSS- based) radar vectoring by ATC, non-GNSS-based navigation systems or the possibility to reach VMC. Examples of contingency actions include: seeking navigational assistance from ATS, using communication and surveillance systems that remain operational, to enable safe descent to VMC; the emergency use of navigation equipment not meeting the requirements of NCO.IDE.A/H.100 by making use of the provisions in NCO.GEN.105(e); descent over water or very flat terrain to levels with reduced (but reasonable) obstacle clearance; and unusually long periods of dead reckoning.

GM2 NCO.OP.160 Meteorological conditions EVALUATION OF METEOROLOGICAL CONDITIONS — AEROPLANES AND HELICOPTERS It is recommended that the pilot-in-command carefully evaluates the available meteorological information relevant to the proposed flight, such as applicable surface observations, winds, temperatures aloft, terminal and area forecasts, air meteorological information reports (AIRMETs), significant meteorological information (SIGMET) and pilot reports. The ultimate decision whether, when, and where to make the flight rests with the pilot-in-command. The pilot-in-command also should continue to re-evaluate changing weather conditions. NCO.OP.165 Ice and other contaminants – ground procedures The pilot-in-command shall only commence take-off if the aircraft is clear of any deposit that might adversely affect the performance or controllability of the aircraft, except as permitted in the AFM. NCO.OP.170 Ice and other contaminants – flight procedures (a) The pilot-in-command shall only commence a flight or intentionally fly into expected or actual icing conditions if the aircraft is certified and equipped to cope with such conditions as referred to in 2 (e) of MCAR Air Operations, ERO.OPS.120. (b) If icing exceeds the intensity of icing for which the aircraft is certified or if an aircraft not certified for flight in known icing conditions encounters icing, the pilot-in-command shall exit the icing conditions without delay, by a change of level and/or route, and if necessary by declaring an emergency to ATC. GM1 NCO.OP.170(b) Ice and other contaminants – flight procedures KNOWN ICING CONDITIONS Known icing conditions are conditions where actual ice is observed visually to be on the aircraft by the pilot or identified by on-board sensors. Issue 1.00 Page 58 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES NCO.OP.175 Take-off conditions — aeroplanes and helicopters Before commencing take-off, the pilot-in-command shall be satisfied that: (a) according to the information available, the meteorological conditions at the aerodrome or the operating site and the condition of the runway/FATO intended to be used will not prevent a safe take-off and departure; and (b) the selected aerodrome operating minima are consistent with all of the following: (1) the operative ground equipment; (2) the operative aircraft systems; (3) the aircraft performance; (4) flight crew qualifications. AMC1 NCO.OP.175 Take-off conditions — aeroplanes and helicopters METEOROLOGICAL CONDITIONS FOR TAKE-OFF — AEROPLANES (a) When the reported visibility is below that required for take-off and RVR is not reported, a take-off should only be commenced if the pilot-in-command can determine that the visibility along the take- off runway/area is equal to or better than the required minimum. (b) When no reported visibility or RVR is available, a take-off should only be commenced if the pilot-in- command can determine that the RVR/VIS along the take-off runway/area is equal to or better than the required minimum. NCO.OP.180 Simulated situations in flight (a) The pilot-in-command shall, when carrying passengers or cargo, not simulate: (1) situations that require the application of abnormal or emergency procedures; or (2) flight in instrument meteorological conditions (IMC). (b) Notwithstanding (a), when training flights are conducted by a training organisation referred to in Article 10a of MCAR Aircrew, such situations may be simulated with student pilots on-board. GM1.NCO.OP.180 Simulated situations in flight DESIGNATION OF PERSONS AS CREW MEMBERS (a) The operator may designate any person as a crew member (including a task specialist) provided that: (1) the role, according to the reasonable expectation of the operator, will enhance the safety of the flight or achieve an operational objective of the flight; (2) the person, according to the reasonable expectation of the operator, is capable of fulfilling the role; Issue 1.00 Page 59 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (3) the person has been briefed on the role as a crew member and informed that they are crew, not a passenger; and (4) the person agrees to the role as a crew member. (b) Crew members are not considered to be passengers. (c) Crew members may be required, by specific provisions of this Regulation and other Implementing Rules, to hold licences, ratings or other personnel certificates to fulfil certain roles such as instructor, examiner or flight engineer in certain circumstances. NCO.OP.185 In-flight fuel/energy management (a) The pilot-in-command shall monitor the amount of usable fuel/energy remaining on board to ensure that it is protected and not less than the fuel/energy that is required to proceed to an aerodrome or operating site where a safe landing can be made. (b) The pilot-in-command of a controlled flight shall advise air traffic control (ATC) of a ‘minimum fuel/energy’ state by declaring ‘MINIMUM FUEL’ when the pilot-in-command has: (1) committed to land at a specific aerodrome or operating site; and (2) calculated that any change to the existing clearance to that aerodrome or operating site, or other air traffic delays, may result in landing with less than the planned final reserve fuel/energy. (c) The pilot-in-command of a controlled flight shall declare a situation of ‘fuel/energy emergency’ by broadcasting ‘MAYDAY MAYDAY MAYDAY FUEL’ when the usable fuel/energy estimated to be available upon landing at the nearest aerodrome or operating site where a safe landing can be made is less than the planned final reserve fuel/energy. GM1 NCO.OP.185(b)&(c) In-flight fuel/energy management ‘MINIMUM FUEL’ DECLARATION (a) The pilot-in-command may consider reporting the remaining fuel/energy endurance after a ‘MINIMUM FUEL’ or ‘MAYDAY MAYDAY MAYDAY FUEL’ declaration. Note: For MCAR-NCO operators, the FRF/energy varies; therefore, the ATC may not be aware of the amount of the remaining fuel/energy endurance. (b) The ‘MINIMUM FUEL’ declaration informs the ATC that all planned landing options have been reduced to a specific aerodrome or operating site of intended landing, and that for helicopters, no other landing site is available. It also informs the ATC that any change to the existing clearance may result in landing with less than the planned FRF/energy. This is not an emergency situation but an indication that an emergency situation is possible, should any additional delay occur. The pilot should not expect any form of priority handling as a result of a ‘MINIMUM FUEL’ declaration. However, the ATC should advise the flight crew of any additional expected delays, as well as coordinate with other ATC units when transferring the control of the aircraft, to ensure that the other ATC units are aware of the flight’s fuel/energy state. (c) The requirement for declaring ‘MINIMUM FUEL’ and ‘MAYDAY MAYDAY MAYDAY FUEL’ applies only to controlled flights; however, these declarations may also be made during uncontrolled flights if the pilot-in-command considers this advisable. Issue 1.00 Page 60 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES NCO.OP.190 Use of supplemental oxygen (a) The pilot-in-command shall ensure that all flight crew members engaged in performing duties essential to the safe operation of an aircraft in flight use supplemental oxygen continuously whenever he/she determines that at the altitude of the intended flight the lack of oxygen might result in impairment of the faculties of crew members, and shall ensure that supplemental oxygen is available to passengers when lack of oxygen might harmfully affect passengers. (b) In any other case when the pilot-in-command cannot determine how the lack of oxygen might affect all occupants on board, he/she shall ensure that: (1) all crew members engaged in performing duties essential to the safe operation of an aircraft in flight use supplemental oxygen for any period in excess of 30 minutes when the pressure altitude in the the passenger compartment will be between 10 000 ft and 13 000 ft; and (2) all occupants use supplemental oxygen for any period that the pressure altitude in the the passenger compartment will be above 13 000 ft. AMC1 NCO.OP.190(a) Use of supplemental oxygen DETERMINATION OF SUPPLEMENTAL OXYGEN NEED When determining the need for supplemental oxygen carriage and use, the pilot-in-command should: (a) in the preflight phase: (1) be aware of hypoxia conditions and associated risks; (2) consider the following objective conditions for the intended flight: (i) altitude; (ii) duration of the flight; and (iii) any other relevant operational conditions. (3) consider individual conditions of flight crew members and passengers in relation to: (i) altitude of the place of residence; (ii) smoking; (iii) experience in flights at high altitudes; (iv) actual medical conditions and medications; (v) age (vi) disabilities; and (vii) any other relevant factor that may be detected, or reported by the person; and (4) when relevant, ensure that all flight crew members and passengers are briefed on hypoxia conditions and symptoms, as well as on the usage of supplemental oxygen equipment. (b) during flight: (1) monitor for early symptoms of hypoxia conditions; and (2) if detecting early symptoms of hypoxia conditions: (i) consider to return to a safe altitude, and Issue 1.00 Page 61 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (ii) ensure that supplemental oxygen is used, if available. GM1 NCO.OP.190 Use of supplemental oxygen GENERAL (a) The responsibility of the pilot-in-command for safety of all persons on board, as required by NCO.GEN.105(a)(1), includes the determination of need for supplemental oxygen use. (b) The altitudes above which NCO.OP.190(b) requires oxygen to be available and used are applicable to those cases when the pilot-in-command cannot determine the need for supplemental oxygen. However, if the pilot-in-command is able to make this determination, he/she may elect in the interest of safety to require oxygen also for operations at or below such altitudes. (c) The pilot-in-command should be aware that flying below altitudes mentioned in NCO.OP.190(b) does not provide absolute protection against hypoxia symptoms, should individual conditions and aptitudes be prevalent. GM2 NCO.OP.190 Use of supplemental oxygen DETERMINATION OF OXYGEN NEED — BEFORE FLIGHT Detailed information and guidance on hypoxia conditions and symptoms, content of the briefing on hypoxia and assessment of individual conditions may be found in the EASA leaflet ‘Hypoxia’. DETERMINATION OF OXYGEN NEED — IN FLIGHT Several methods for monitoring hypoxia early symptoms may be used and some methods may be aided by personal equipment, such as finger-mounted pulse oximeters. Detailed information and guidance on entering hypoxia conditions, on hypoxia symptoms early detection, and on use of personal equipment such as finger-mounted pulse oximeters or equivalent may be found in the EASA leaflet ‘Hypoxia’. NCO.OP.195 Ground proximity detection When undue proximity to the ground is detected by the pilot-in-command or by a ground proximity warning system, the pilot-in-command shall take corrective action immediately in order to establish safe flight conditions. NCO.OP.200 Airborne collision avoidance system (ACAS II) When ACAS II is used, operational procedures and training shall be in accordance with MCAR part CAT. NCO.OP.205 Approach and landing conditions — aeroplanes Before commencing an approach to land, the pilot-in-command shall be satisfied that: Issue 1.00 Page 62 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (a) according to the information available, the meteorological conditions at the aerodrome or the operating site, and the condition of the runway intended to be used will not prevent a safe approach, landing, or missed approach; and (b) the selected aerodrome operating minima are consistent with all of the following: (1) the operative ground equipment; (2) the operative aircraft systems; (3) the aircraft performance, and (4) flight crew qualifications. AMC1 NCO.OP.205 Approach and landing conditions – aeroplanes LANDING DISTANCE ASSESSMENT (a) The in-flight landing distance assessment should be based on the latest available weather report and, if available, runway condition report (RCR). (b) The assessment should be initially carried out when weather report and RCR, if available, are obtained, usually around top of descent. If the planned duration of the flight does not allow to carry out the assessment in non-critical phases of flight, the assessment should be carried out before departure. (c) When meteorological conditions may lead to a degradation of the runway surface condition, the assessment should include consideration of how much deterioration in runway surface friction characteristics may be tolerated, so that a quick decision can be made prior to landing. (d) Whenever the RCR is in use and the runway braking action encountered during the landing roll is not as good as reported by the aerodrome operator in the RCR, the pilot-in-command should notify the air traffic services (ATS) by means of a special air-report (AIREP) as soon as practicable. GM1 NCO.OP.205 Approach and landing conditions — aeroplanes RUNWAY CONDITION REPORT (RCR) When the aerodrome reports the runway conditions by means of an RCR, the information contained therein includes a runway condition code (RWYCC). The determination of the RWYCC is based on the use of the runway condition assessment matrix (RCAM). The RCAM correlates the RWYCC with the contaminants present on the runway and the braking action. A detailed description of the RCR format and content, the RWYCC and the RCAM may be found in MCAR- 139 and in MCAR part CAT Further guidance may be found in the following documents: (a) ICAO Doc 9981 ‘PANS Aerodromes’; (b) ICAO Doc 4444 ‘PANS ATM’; (c) ICAO Doc 10064 ‘Aeroplane Performance Manual’; and (d) ICAO Circular 355 ‘Assessment, Measurement and Reporting of Runway Surface Conditions’. Issue 1.00 Page 63 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES NCO.OP.206 Approach and landing conditions — helicopters Before commencing an approach to land, the pilot-in-command shall be satisfied that: (a) according to the information available, the meteorological conditions at the aerodrome or the operating site and the condition of the final approach and take-off area (FATO) intended to be used will not prevent a safe approach, landing or missed approach; and (b) the selected aerodrome operating minima are consistent with all of the following: (1) the operative ground equipment; (2) the operative aircraft systems; (3) the aircraft performance; (4) flight crew qualifications. AMC1 NCO.OP.206 Approach and landing conditions — helicopters FATO SUITABILITY The in-flight determination of the FATO suitability should be based on the latest available meteorological report. NCO.OP.210 Commencement and continuation of approach — aeroplanes and helicopters (a) If the controlling RVR for the runway to be used for landing is less than 550 m (or any lower value established in accordance with an approval under SPA.LVO), then an instrument approach operation shall not be continued: (1) past a point at which the aircraft is 1 000 ft above the aerodrome elevation; or (2) into the final approach segment if the DH or MDH is higher than 1 000 ft. (b) If the required visual reference is not established, a missed approach shall be executed at or before the DA/H or the MDA/H. (c) If the required visual reference is not maintained after DA/H or MDA/H, a go-around shall be executed promptly. AMC1 NCO.OP.210 Commencement and continuation of approach — aeroplanes and helicopters VISUAL REFERENCES (a) For a straight-in approach, at DH or MDH, at least one of the visual references specified below should be distinctly visible and identifiable to the pilot: (1) elements of the approach lighting system; (2) the threshold; (3) the threshold markings; Issue 1.00 Page 64 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES (4) the threshold lights; (5) the threshold identification lights; (6) the visual glide path indicator; (7) the touchdown zone (TDZ) or TDZ markings; (8) the TDZ lights; (9) FATO/runway edge lights; (10) for helicopter PinS approaches, the identification beacon light and visual ground reference; (11) for helicopter PinS approaches, the identifiable elements of the environment defined on the instrument chart; or (12) for helicopter PinS approaches with instructions to ‘proceed VFR’, sufficient visual cues to determine that the conditions for VFR are met. (b) For a circling approach, the required visual reference is the runway environment. AMC2 NCO.OP.210 Commencement and continuation of approach — aeroplanes and helicopters RVR MINIMA FOR CONTINUED APPROACH (a) The controlling RVR should be the touchdown RVR. (b) If the touchdown RVR is not reported, then the midpoint RVR should be the controlling RVR. (c) If neither the touchdown RVR nor the midpoint RVR is reported, then NCO.OP.210(a) is not applicable. GM1 NCO.OP.210 Commencement and continuation of approach — aeroplanes and helicopters APPLICATION OF RVR REPORTS (a) There is no prohibition on the commencement of an approach based on reported RVR. The restriction in NCO.OP.210 applies only if the RVR is reported and applies to the continuation of the approach past a point where the aircraft is 1 000 ft above the aerodrome elevation or into the final approach segment (FAS) as applicable. (b) If a deterioration in the RVR is reported once the aircraft is below 1 000 ft on the FAS, as applicable, then there is no requirement for the approach to be discontinued. In this situation, the normal visual reference requirements would apply at the DA/H. (c) Where additional RVR information is provided (e.g. midpoint and stop end), this is advisory; such information may be useful to the pilot in order to determine whether there will be sufficient visual reference to control the aircraft during roll-out and taxi. (d) If the RVR is less than the RVR calculated in accordance with AMC3 NCO.OP.110, a go-around is likely to be necessary since visual reference may not be established at the DH, or at the MDH at a point where a stable approach to landing in the TDZ remains possible. Similarly, in the absence of an RVR report, the reported visibility may indicate that a go-around is likely. The pilot-in-command should Issue 1.00 Page 65 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority OPERATIONAL PROCEDURES consider available options, based on a thorough assessment of risk, such as diverting to an alternate, before commencing the approach. NCO.OP.220 Airborne collision avoidance system (ACAS II) When ACAS II is used, pilot-in-command shall apply the appropriate operational procedures and be adequately trained.

(b) Placards, listings, instrument markings, or combinations thereof, containing those operating limitations prescribed by the AFM for visual presentation, shall be displayed in the aircraft. NCO.POL.105 Weighing (a) The operator shall ensure that the mass and, the CG of the aircraft have been established by actual weighing prior to the initial entry into service of the aircraft. The accumulated effects of modifications and repairs on the mass and balance shall be accounted for and properly documented. Such information shall be made available to the pilot-in-command. The aircraft shall be reweighed if the effect of modifications on the mass and balance is not accurately known. (b) The weighing shall be accomplished by the manufacturer of the aircraft or by an approved maintenance organisation. GM1 NCO.POL.105 Weighing GENERAL (a) New aircraft that have been weighed at the factory may be placed into operation without reweighing if the mass records and, balance records have been adjusted for alterations or modifications to the aircraft. Aircraft transferred from one EU operator to another EU operator do not have to be weighed prior to use by the receiving operator, unless the mass and balance cannot be accurately established by calculation. (b) The mass and centre of gravity (CG) position should be revised whenever the cumulative changes to the dry operating mass exceed ± 0.5 % of the maximum landing mass or, for aeroplanes, the cumulative change in CG position exceeds 0.5 % of the mean aerodynamic chord.

(c) Location (1) Forward-facing child seats may be installed on both forward-and rearward-facing passenger seats, but only when fitted in the same direction as the passenger seat on which they are Issue 1.00 Page 76 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority INSTRUMENTS, DATA AND EQUIPMENT positioned. Rearward-facing child seats should only be installed on forward-facing passenger seats. A child seat may not be installed within the radius of action of an airbag unless it is obvious that the airbag is de-activated or it can be demonstrated that there is no negative impact from the airbag. (2) An infant/child in a CRD should be located in the vicinity of a floor level exit. (3) An infant/child in a CRD should not hinder evacuation for any passenger. (d) Installation (1) CRDs tested and approved for use in aircraft should only be installed on a suitable passenger seat by the method shown in the manufacturer’s instructions provided with each CRD and with the type of connecting device they are approved for the installation in aircraft. CRDs designed to be installed only by means of rigid bar lower anchorages (ISOFIX or equivalent) should only be used on passenger seats equipped with such connecting devices and should not be secured by passenger seat lap belt. (2) All safety and installation instructions should be followed carefully by the responsible adult accompanying the infant/child. Operators should prohibit the use of a CRD not installed on the passenger seat according to the manufacturer’s instructions or not approved for use in aircraft. (3) If a forward-facing child seat with a rigid backrest is to be fastened by a seat lap belt, the restraint device should be fastened when the backrest of the passenger seat on which it rests is in a reclined position. Thereafter, the backrest is to be positioned upright. This procedure ensures better tightening of the child seat on the aircraft seat if the aircraft seat is reclinable. (4) The buckle of the adult safety belt should be easily accessible for both opening and closing, and should be in line with the seat belt halves (not canted) after tightening. (5) Forward-facing restraint devices with an integral harness must not be installed such that the adult safety belt is secured over the infant. (e) Operation (1) Each CRD should remain secured to a passenger seat during all phases of flight unless it is properly stowed when not in use. (2) Where a child seat is adjustable in recline, it should be in an upright position for all occasions when passenger restraint devices are required.

The ELT can be tethered to a survivor or a life-raft. This type of ELT is intended to aid SAR teams in locating the crash site or survivor(s). (3) Automatic deployable (ELT(AD)). An ELT that is rigidly attached to the aircraft before the crash and that is automatically deployed and activated by an impact, and, in some cases, also by water sensors. This type of ELT should float in water and is intended to aid SAR teams in Issue 1.00 Page 82 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority INSTRUMENTS, DATA AND EQUIPMENT locating the crash site. The ELT(AD) may be either a stand-alone beacon or an inseparable part of a deployable recorder. (4) Survival ELT (ELT(S)). An ELT that is removable from an aircraft, stowed so as to facilitate its ready use in an emergency and manually activated by a survivor. An ELT(S) may be activated manually or automatically (e.g. by water activation). It should be designed either to be tethered to a life-raft or a survivor. A water-activated ELT(S) is not an ELT(AP). (b) To minimise the possibility of damage in the event of crash impact, the automatic ELT should be rigidly fixed to the aircraft structure, as far aft as is practicable, with its antenna and connections arranged so as to maximise the probability of the signal being transmitted after a crash. (c) Any ELT carried should operate in accordance with the relevant provisions of ICAO Annex 10, Volume III, and should be registered with the national agency responsible for initiating search and rescue or other nominated agency.

AMC1 NCO.IDE.A.195 Navigation equipment NAVIGATION WITH VISUAL REFERENCE TO LANDMARKS Where aeroplanes, with the surface in sight, can proceed according to the ATS flight plan by navigation with visual reference to landmarks, no additional equipment is needed to comply with NCO.IDE.A.195(a)(1). GM1 NCO.IDE.A.195 Navigation equipment AIRCRAFT ELIGIBILITY FOR PBN SPECIFICATION NOT REQUIRING SPECIFIC APPROVAL (a) The performance of the aircraft is usually stated in the AFM/POH. (b) Where such a reference cannot be found in the AFM/POH, other information provided by the aircraft manufacturer as TC holder, the STC holder or the design organisation having a privilege to approve minor changes may be considered. (c) The following documents are considered acceptable sources of information: (1) AFM/POH, supplements thereto, and documents directly referenced in the AFM/POH; (2) FCOM or similar document; (3) Service Bulletin or Service Letter issued by the TC holder or STC holder; (4) approved design data or data issued in support of a design change approval; (5) any other formal document issued by the TC or STC holders stating compliance with PBN specifications, AMC, Advisory Circulars (AC) or similar documents issued by the State of Design; and (6) written evidence obtained from the State of Design. (d) Equipment qualification data, in itself, is not sufficient to assess the PBN capabilities of the aircraft, since the latter depend on installation and integration. Issue 1.00 Page 87 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority INSTRUMENTS, DATA AND EQUIPMENT (e) As some PBN equipment and installations may have been certified prior to the publication of the PBN Manual and the adoption of its terminology for the navigation specifications, it is not always possible to find a clear statement of aircraft PBN capability in the AFM/POH. However, aircraft eligibility for certain PBN specifications can rely on the aircraft performance certified for PBN procedures and routes prior to the publication of the PBN Manual. (f) Below, various references are listed which may be found in the AFM/POH or other acceptable documents (see listing above) in order to consider the aircraft’s eligibility for a specific PBN specification if the specific term is not used.

(ii) If there is a reference to RF and a reference to compliance with AC 90-105, then the aircraft is eligible for such operations. (q) Other considerations (1) In all cases, the limitations in the AFM/POH need to be checked, in particular the use of AP or FD which can be required to reduce the FTE primarily for RNP APCH, RNAV 1, and RNP 1. (2) Any limitation such as ‘within the US National Airspace’ may be ignored since RNP APCH procedures are assumed to meet the same ICAO criteria around the world. GM2 NCO.IDE.A.195 Navigation equipment GENERAL (a) The PBN specifications for which the aircraft complies with the relevant airworthiness criteria are set out in the AFM/POH, together with any limitations to be observed. (b) Because functional and performance requirements are defined for each navigation specification, an aircraft approved for an RNP specification is not automatically approved for all RNAV specifications. Similarly, an aircraft approved for an RNP or RNAV specification having a stringent accuracy requirement (e.g. RNP 0.3 specification) is not automatically approved for a navigation specification having a less stringent accuracy requirement (e.g. RNP 4). RNP 4 (c) For RNP 4, at least two LRNSs, capable of navigating to RNP 4, and listed in the AFM/POH, may be operational at the entry point of the RNP 4 airspace. If an item of equipment required for RNP 4 operations is unserviceable, then the pilot-in-command may consider an alternate route or diversion for repairs. For multi-sensor systems, the AFM/POH may permit entry if one GNSS sensor is lost after departure, provided one GNSS and one inertial sensor remain available. AMC1 NCO.IDE.A.195(a) Navigation equipment NAVIGATION EQUIPMENT — RNAV SUBSTITUTION An RNAV system may be used to substitute for conventional navigation aids and radio equipment, without monitoring of the raw data from conventional navigation aids, under the following conditions: SCOPE OF RNAV SUBSTITUTION (a) RNAV substitution may be used in all the phases of flight except: (1) to provide lateral guidance in the FAS of an IAP; and (2) to substitute for DME, if a DME transceiver is either not installed on the aircraft or found to be unserviceable before flight. SUITABILITY OF THE RNAV SYSTEM FOR RNAV SUBSTITUTION (b) The RNAV system should meet: Issue 1.00 Page 91 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority INSTRUMENTS, DATA AND EQUIPMENT (1) at least the requirements of (E)TSO-C129/-C196/-C145/-C146 (or later equivalent standards); and (2) the requirements of NCO.OP.116(a) for RNAV 1, RNP 1 or RNP APCH as regards its installation in the aircraft. OPERATING PROCEDURE (c) The pilot-in-command is responsible for: (1) ensuring that any procedure and waypoints used are retrieved from a navigation database which meets the requirements of NCO.IDE.A.205; (2) verifying waypoint sequence, reasonableness of track angles, and distances of any overlay procedure used; (3) applying pre-flight procedures associated with GNSS use (e.g. RAIM check if applicable); and (4) complying with any limitation on RNAV substitution in the AFM. PILOT COMPETENCE (d) The pilot-in-command should be aware of the limitations of RNAV substitution. AIRSPACE LIMITATIONS (e) RNAV substitution should not be applied on any procedure where RNAV substitution has been indicated as ‘not authorised’ by an AIP entry or a notice to airmen (NOTAM). CONTINGENCY PLANNING (f) Nothing in this AMC relieves the pilot-in-command from compliance with NCO.IDE.A.195(b) which requires sufficient navigation equipment to ensure that, in the event of the failure of one item of equipment at any stage of the flight, the remaining equipment shall allow safe navigation according to the flight plan, or an appropriate contingency action, to be completed safely. GM1 NCO.IDE.A.195(a) Navigation equipment NAVIGATION EQUIPMENT — SCOPE OF RNAV SUBSTITUTION (a) Applications of RNAV substitution include use to: (1) determine aircraft position relative to or distance from a VOR, marker, DME fix or a named fix defined by a VOR radial or NDB bearing; (2) navigate to or from a VOR, or NDB, except as lateral guidance in the FAS of an IAP; (3) hold over a VOR, NDB, or DME fix; (4) fly an arc based upon DME; (5) fly an overlay of a conventional departure, arrival, approach or route except as lateral guidance in the FAS of an IAP. (b) RNAV substitution for ADF, marker and VOR may be used where airborne and/or ground-based equipment is not available. Issue 1.00 Page 92 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority INSTRUMENTS, DATA AND EQUIPMENT (c) RNAV substitution for DME may be used where the ground-based DME transponder is unserviceable or the airborne DME transceiver is found to be unserviceable in flight. Caution must be exercised by the pilot-in-command when calculating and using GNSS distances to the active waypoint as reference points are often different. GM2 NCO.IDE.A.195(a) Navigation equipment NAVIGATION EQUIPMENT — SUITABILITY OF THE RNAV SYSTEM FOR RNAV SUBSTITUTION GNSS (E)TSOs are referenced in AMC1 NCO.IDE.A.195(a) since most of the aircraft conducting NCO are equipped with an RNAV stand-alone system which exclusively bases its positioning on GNSS. GM3 NCO.IDE.A.195(a) Navigation equipment NAVIGATION EQUIPMENT — RNAV SUBSTITUTION — OPERATING PROCEDURE Although RNAV substitution may not be used for lateral guidance in the FAS, this does not preclude the use of the RNAV system to fly the FAS, provided that raw data from the associated conventional navigation aids is monitored. AMC1 NCO.IDE.A.195(b) Navigation equipment APPROPRIATE CONTINGENCY ACTION An appropriate contingency action is an alternative offered in NCO.IDE.A.195(b) to completion of the planned flight to a safe landing, either at the planned destination or a destination alternate, using normal procedures and using navigation equipment meeting the requirements of NCO.IDE.A.100, installed for redundancy or as a backup. The contingency action should be considered before flight and take into account the information identified by flight preparation according to NCO.OP.135. It may depend on the flight and availability of navigation solutions (satellites, ground navaids, etc.) and weather conditions (IMC, VMC) along the flight. The contingency action addresses partial loss of navigation capability. An appropriate contingency action to meet the requirements of NCO.IDE.A.195(b) does not rely on the performance of any function of the item of equipment whose potential failure is being considered. For example, in considering the failure of a VOR/LOC/DME receiver, none of the functions of that receiver should be relied upon in the contingency action. Examples of contingency actions include: seeking navigational assistance from ATS, using communication, navigation and surveillance systems that remain operational, to enable a safe instrument approach or a safe descent to VMC; unusually long periods of dead reckoning. A contingency action is required such that the failure of one item of navigation equipment has a reasonable likelihood of a safe outcome to the flight, consistent with other risks to which the operation is exposed.

AMC1 NCO.IDE.A.200 Transponder GENERAL (a) The secondary surveillance radar (SSR) transponders of aeroplanes being operated under European air traffic control should comply with any applicable Single European Sky legislation. (b) If the Single European Sky legislation is not applicable, the SSR transponders should operate in accordance with the relevant provisions of Volume IV of ICAO Annex 10. NCO.IDE.A.205 Management of aeronautical databases (a) Aeronautical databases used on certified aircraft system applications shall meet data quality requirements that are adequate for the intended use of the data. (b) The pilot-in-command shall ensure the timely distribution and insertion of current and unaltered aeronautical databases to the aircraft that require them. (c) Notwithstanding any other occurrence reporting requirements, the pilot-in-command shall report to the database provider instances of erroneous, inconsistent or missing data that might be reasonably expected to constitute a hazard to flight. In such cases, the pilot-in-command shall not use the affected data. AMC1 NCO.IDE.A.205 Management of aeronautical databases AERONAUTICAL DATABASES When the operator of an aircraft uses an aeronautical database that supports an airborne navigation application as a primary means of navigation used to meet the airspace usage requirements, the database provider should be a Type 2 DAT provider certified in accordance with applicable regulations.

(b) Where such a reference cannot be found in the AFM/POH, other information provided by the aircraft manufacturer as TC holder, the STC holder or the design organisation having a privilege to approve minor changes may be considered. (c) The following documents are considered acceptable sources of information: (1) AFM/POH, supplements thereto, and documents directly referenced in the AFM/POH; (2) FCOM or similar document; (3) Service Bulletin or Service Letter issued by the TC holder or STC holder; (4) approved design data or data issued in support of a design change approval; (5) any other formal document issued by the TC or STC holders stating compliance with PBN specifications, AMC, Advisory Circulars (AC) or similar documents issued by the State of Design; and (6) written evidence obtained from the State of Design. (d) Equipment qualification data, in itself, is not sufficient to assess the PBN capabilities of the aircraft, since the latter depend on installation and integration. (e) As some PBN equipment and installations may have been certified prior to the publication of the PBN Manual and the adoption of its terminology for the navigation specifications, it is not always possible to find a clear statement of aircraft PBN capability in the AFM/POH. However, aircraft eligibility for certain PBN specifications can rely on the aircraft performance certified for PBN procedures and routes prior to the publication of the PBN Manual. (f) Below, various references are listed which may be found in the AFM/POH or other acceptable documents (see listing above) in order to consider the aircraft’s eligibility for a specific PBN specification if the specific term is not used.

Issue 1.00 Page 116 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority INSTRUMENTS, DATA AND EQUIPMENT GM3 NCO.IDE.H.195 Navigation equipment GENERAL (a) The PBN specifications for which the aircraft complies with the relevant airworthiness criteria are set out in the AFM/POH, together with any limitations to be observed. (b) Because functional and performance requirements are defined for each navigation specification, an aircraft approved for an RNP specification is not automatically approved for all RNAV specifications. Similarly, an aircraft approved for an RNP or RNAV specification having a stringent accuracy requirement (e.g. RNP 0.3 specification) is not automatically approved for a navigation specification having a less stringent accuracy requirement (e.g. RNP 4). RNP 4 (c) For RNP 4, at least two LRNSs, capable of navigating to RNP 4, and listed in the AFM/POH, may be operational at the entry point of the RNP 4 airspace. If an item of equipment required for RNP 4 operations is unserviceable, then the pilot-in-command may consider an alternate route or diversion for repairs. For multi-sensor systems, the AFM/POH may permit entry if one GNSS sensor is lost after departure, provided one GNSS and one inertial sensor remain available. AMC1 NCO.IDE.H.195(a) Navigation equipment NAVIGATION EQUIPMENT — RNAV SUBSTITUTION An RNAV system may be used to substitute for conventional navigation aids and radio equipment, without monitoring of the raw data from conventional navigation aids, under the conditions defined in AMC1 NCO.IDE.A.195(a). GM1 NCO.IDE.H.195(a) Navigation equipment NAVIGATION EQUIPMENT — SCOPE OF RNAV SUBSTITUTION (a) Applications of RNAV substitution include use to: (1) determine aircraft position relative to or distance from a VOR, marker, DME fix or a named fix defined by a VOR radial or NDB bearing; (2) navigate to or from a VOR, or NDB, except as lateral guidance in the FAS of an IAP; (3) hold over a VOR, NDB, or DME fix; (4) fly an arc based upon DME; (5) fly an overlay of a conventional departure, arrival, approach or route except as lateral guidance in the FAS of an IAP. (b) RNAV substitution for ADF, marker and VOR may be used where airborne and/or ground-based equipment is not available. (c) RNAV substitution for DME may be used where the ground-based DME transponder is unserviceable or the airborne DME transceiver is found to be unserviceable in flight. Caution must be exercised Issue 1.00 Page 117 of 139 07 May 2025 Maldivian Civil Aviation Regulations MCAR - NCO Maldives Civil Aviation Authority INSTRUMENTS, DATA AND EQUIPMENT by the pilot-in-command when calculating and using GNSS distances to the active waypoint as reference points are often different. GM2 NCO.IDE.H.195(a) Navigation equipment NAVIGATION EQUIPMENT — SUITABILITY OF THE RNAV SYSTEM FOR RNAV SUBSTITUTION GNSS (E)TSOs are referenced in AMC1 NCO.IDE.A.195(a) since most of the aircraft conducting NCO are equipped with an RNAV stand-alone system which exclusively bases its positioning on GNSS. GM3 NCO.IDE.H.195(a) Navigation equipment NAVIGATION EQUIPMENT — RNAV SUBSTITUTION — OPERATING PROCEDURE Although RNAV substitution may not be used for lateral guidance in the FAS, this does not preclude the use of the RNAV system to fly the FAS, provided that raw data from the associated conventional navigation aids is monitored. - document.segment-7 Verify source ↗
Regulation No: 2025/R-49 MCAR-NCO (Non-Commercial Air Operations with Other-than-complex Motor-powered aircraft) — segment 7
AI-assisted research summary: This segment sets operational rules for specialised and related flight operations, including checklists, briefings, oxygen use, flight-altitude limits, dangerous-goods restrictions, and some maintenance check flight exceptions.
AMC1 NCO.IDE.H.195(b) Navigation equipment APPROPRIATE CONTINGENCY ACTION An appropriate contingency action is an alternative offered in NCO.IDE.H.195(b) to completion of the planned flight to a safe landing, either at the planned destination or a destination alternate, using normal procedures and using navigation equipment meeting the requirements of NCO.IDE.H.100, installed for redundancy or as a backup. The contingency action should be considered before flight and take into account the information identified by flight preparation according to NCO.OP.135. It may depend on the flight and availability of navigation solutions (satellites, ground navaids, etc.) and weather conditions (IMC, VMC) along the flight. The contingency action addresses partial loss of navigation capability. An appropriate contingency action to meet the requirements of NCO.IDE.H.195(b) does not rely on the performance of any function of the item of equipment whose potential failure is being considered. For example, in considering the failure of a VOR/LOC/DME receiver, none of the functions of that receiver should be relied upon in the contingency action. Examples of contingency actions include: seeking navigational assistance from ATS, using communication, navigation and surveillance systems that remain operational, to enable a safe instrument approach or a safe descent to VMC; unusually long periods of dead reckoning. A contingency action is required such that the failure of one item of navigation equipment has a reasonable likelihood of a safe outcome to the flight, consistent with other risks to which the operation is exposed.
