About this statute
This regulation sets requirements for Maldives aeronautical information and charts services, including reference systems, service provision, quality management, and data handling. The AIRAC information service must time certain notices and updates so recipients get advance notice, and aeronautical charts services must keep charts available, accurate, current, and technically compliant. The aeronautical charts service provider must prepare and display required chart information, including magnetic bearings/tracks/radials, magnetic variation, aerodromes, air traffic services data, and other chart details specified for the chart type. The aeronautical chart service provider must include specified chart information, such as elevations, aerodromes, obstacles, navigation aids, and airspace features, and must make available the ICAO plotting chart. This appendix lists aeronautical chart symbols and related terms with their page references.
