Abstract:
A flight control device for an aircraft, comprising:a control unit OP;a plurality of N instruction generating systems, each of said instruction generating systems generating a first command instruction for said control unit OP and a least one of said instruction generating systems performing autosurveillance and generating a corresponding surveillance signal, each of said instruction generating systems being assigned a relative priority; anda plurality of P servocontrol systems, each of said servocontrol systems being coupled to each of said instruction generating systems so that each of said servocontrol systems receives one of said first command instructions from each of said instruction generating systems, each of said servocontrol systems receiving information identifying a particular position of a flight control unit and each of said servocontrol systems communicating a second command instruction to said control unit OP based on said information, each of said servo control systems comprising:selector means that receives one of said first command instructions from each of said instruction generating systems, said selector means selecting one of said first command instructions in accordance with said relative priority of said instruction generating systems; andcomputing means coupled to said selector means, said computing means generating one of said second command instructions based on said first command instructions selected by said selector means and said surveillance signal.
