Abstract
A distributed control system is provided where the controllers are split into two dissimilar groups and flight control responsibility is further allocated within each group such that one entire group plus one further controller can fail without compromising the pilot's ability to fly the aircraft.
Claims20
A flight surface control system for an aircraft, the control system comprising first and second groups of controllers arranged such that in the event of failure of the entirety of one of the groups of controllers and the failure of a further controller the remaining operative controllers control sufficient ones of the flight surfaces to provide continued safe flight and landing, and further including analogue controllers independent from the digital control circuitry for providing control of sufficient flight surfaces to provide continued safe flight and landing in the event of failure of all the digital controllers.
