Flight Management System (FMS) Subcommittee

Last Update: May 10, 2010

Goal: Maintain ARINC 702A, Advanced Flight Management Computer System, in particular definition of aircraft state data and flight path trajectory information sourced by the FMS. Work with international airspace providers to ensure that FMS will fulfill its role enabling airlines to achieve operational benefits and positive return on investment. This work involves close coordination with RTCA SC-186 ADS-B.

Scope: The project will define a format for encoding and communicating aircraft state data and trajectory intent data to users on the airplane using both networked topology, e.g., Ethernet and ARINC 429. This data format, when designed and implemented, will enable all user systems to determine the tactical and strategic intent of the airplane.

Benefit: The FMS provides operational flexibility both terminal and enroute operations. It provides access to airspace with Required Navigation Performance (RNP). FMS data is used to obtain user-preferred trajectory, for noise abatement procedures and for reduced fuel burn. The FMS will enable ADS-B applications to be implemented that support real time traffic conflict probe. Trajectory data can be used with Terrain Awareness and Warning System (TAWS) to verify terrain clearances.

AEEC General Session (October 2006) Update:

AEEC adopted the following document:

Draft 2 of Supplement 3 to ARINC Characteristic 702A: Advanced Flight Management Computer System (FMS)

AEEC endorsed the work program that would update ARINC 702A as necessary to support ADS-B applications. This includes update to aircraft state data and trajectory intent data anticipated for CNS/ATM operation.
