A fault-tolerant data multiplexing and transmission system for fly-by-wire flight control application was successfully flight tested. The Fault-Tolerant Digital Airborne Data System (F-DADS) was adapted and installed as a link in the fly-by-wire flight control system of the USAF/CALSPAN Total In-Flight Simulator (TIFS) aircraft. Sixteen analog signals, including pilot inputs, (elevator, rudder, etc.), autopilot feedback, (attitude, rates, etc.), were time multiplexed and transmitted via a serial digital data bus. F-DADS data terminals were redundant for failure protection. In addition to a conventional twisted pair wire data bus the multiplex link was operated with a fiber optic data bus and a microwave data bus which are immune to almost all types of electromagnetic interference.
