Abstract : An exploratory development project is described that has resulted in the successful design and demonstration of a fault tolerant data transmission and multiplexing system called the Fault Tolerant Digital Airborne Data System (F-DADS). The F-DADS is a modification of the previously demonstrated Digital Airborne Data System (DADS); incorporating redundancy, fault detection, and reconfiguration to achieve fail-operate performance. A replacement system design approach was selected in which one or more spare terminals are activated to replace faulty units to achieve the level of fault tolerance desired. Data handling and fault tolerant performance of the F-DADS was demonstrated by the design, fabrication and test of a three-terminal brassboard demonstration system. (Author Modified Abstract)
