Abstract : The report presents the results of a study to apply Fault-Tolerance techniques to Avionics Systems Architectures. This study included the following tasks: (1) definition of a general avionics baseline system consisting of Integrated Pilot Controls and Displays, Strapdown Inertial Reference Unit, Fly-By-Wire Automatic Flight Control Subsystem, Multiplex Data Bus, and Distributed Computation Network, (2) development of a fault-tolerant avionics Distributed Computation Subsystem, (3) development of optimum avionics system partitioning, redundancy, implementation, and redundancy management techniques, (4) development of subsystem fault detection, isolation, and recovery techniques, and (5) analysis and determination of the costs versus benefits of fault-tolerant avionics system design.
