The TSO-certified RMS 555 Radio Management System is installed on nearly 500 U.S. Military T6-A trainer aircraft, and consists of the RMU-556 Radio Management Unit, KDA-557 RMS Data Adaptor, and RMS-555 Configuration Module. It is also installed in rotorcraft and various international fixed-wing military trainer aircraft.

Cobham’s solution will update the RMS 555 system by modifying the software/firmware of the RMU-556 and KDA-557 units. This solution significantly reduces the cost and simplifies the aircraft modification to comply with ADS-B Out requirements by allowing the aircraft configuration and pilot interfaces to remain the same.
