Translating the requirements for the forward swept wing (FSW), reduced stability aircraft flight control system into a real hardware system, within cost and schedule constraints, presented a formidable challenge. The sensor computer subsystem (SCSS) represents the hardware used to implement the system. The goal was to satisfy the system requirements using off-the-shelf hardware to the maximum extent possible to reduce risk and development time and cost. A triplex digital system with a triplex analog backup system was chosen to meet the fail operational/fail safe requirement for the digital system and the fail safe requirement for the analog system. The SCSS makes use of extensive self-test and input/output comparisons to satisfy the requirements for a flight safety system. The authors describe how system requirements were converted into the hardware required to provide a triplex digital control system with triplex analog backup. The testing conducted to ensure a flight-worthy flight control system is also described.
