FAULT TOLERANT FLIGHT CONTROL ARCHITECTURE

Abstract: a flight control system, including a flight control computer (fcc) configured for providing a first and second flight function, and sending, to effectors of an aircraft, first command signals based on the first and second flight functions, and a second computer configured for providing one or more autonomy functions associated with operation of the aircraft, and that are different from the first and second flight functions, monitoring operation of the fcc, determining whether the fcc has failed, and providing a fail-safe mode for at least the first flight function in response to determining that the fcc has failed. providing the fail-safe mode includes providing one or more critical flight functions that includes the first flight function, and sending, to the effectors, second command signals that replace a first command signal associated with the first flight function and that are based on the critical flight functions.
