ARINC Specification 633-6:2026

ARINC Specification 633 defines the format and the exchange of Aeronautical Operational Control (AOC) messages. Supplement 6 adds new ARINC 633 AOC data structures as well as revises existing data structures, including: Flight Plans, Special Loads (i.e., Weight and Balance and Cargo Planning Load Sheets), NOTAM, ETOPS, Terrain Avoidance, FuelHeader, Minimum Equipment Lists (MEL), Crew List, etc.





The standardization of AOC messages facilitates the development of applications shared by numerous airlines on different aircraft types. Benefits include improved dispatchability and reduce operator cost. ARINC 633 is a complete definition of AOC message sets used in commercial aviation with XML schema definition.
