The Airborne voice/data radio R&S®XK516 is designed for use in commercial aircraft. The system provides conventional voice and high-speed air-toground, ground-to-air and air-to-air data communication over long distances. The data communication is suitable for aircraft operational communication (AOC), airline administrative communication (AAC) as well as air traffic communication (ATC).
The radio is a joint development of Rohde & Schwarz and Honeywell Aerospace Electronic Systems. The exclusive distribution rights rest with Honeywell Aerospace Electronic Systems, 15001 N.E. 36th Street, Redmond, WA98073-9701, USA.
The data modules which provide the high-speed data function are fully integrated within the transceiver. The voice/data radio therefore fits into the space of the conventional HF voice radio. Additional space for the data capability is not needed. The functioning of the equipment is controlled by the integrated test system that continuously monitors a number of functions. After the test routine has been triggered, the faulty module will be located and indicated. BITE results are reported to the onboard CFDS/CMC system via two ARINC 429 busses.
- Communication is possible by strategically located data link ground stations, which provide access to ARINC and SITA airline networks as well as to Honeywell's global data center
- To provide full compatibility between existing and new equipment as well as aircraft wiring
- Three interfaces between transceiver and antenna coupler are simultaneously available
- The single-wire coaxial interface needs only the coaxial cable to transfer control and BITE information between transceiver and coupler
- High potential for reducing weight
- The retrofitting of older aircraft is simple because it does not depend on the existing aircraft wiring
