Flight Management System (FMS)


Flight Management Computer Standards for emerging airspace requirements are being developed to take advantage of advancements in Communication, Navigation and Surveillance (CNS), all with the collective goal to increase the capacity and efficiency of the airspace.


ARINC Characteristic 702A is being updated to meet OEM requirements for new airplanes. The goal is to prepare Supplement 5 that will be aligned to the applicable RTCA/EUROCAE standards in support of NextGen and SESAR initiatives such as Performance-Based Navigation (PBN) and Trajectory Based Operations (TBO). Many of these evolutions are discussed in ARINC Report 660B and part of the larger CNS/ATM initiatives. These include enhanced datalink, satellite-based approach procedures, airport moving map and guidance, and electronic flight bags. Other evolutions include graphical user interfaces (ARINC 661) and software partitioning (ARINC 653).


This project will advance the NextGen and SESAR operational concepts that will, in turn, provide a number of benefits to airlines, airframe manufacturers, and avionics suppliers. This will include user-preferred trajectories, fuel savings, environmental benefits, and capacity improvements. The FMS activity provides a forum for participants to advance and shape CNS initiatives from an airline and supplier perspective.
