1. An aircraft flight control surface actuation haptic feedback system, comprising:

  • a flight control stick adapted to receive an input force supplied by a pilot and configured, upon receipt of the input force, to move to a control position in a displacement direction;

    a control unit adapted to receive signals representative of aircraft speed, aircraft altitude, aircraft attitude, and aircraft flight envelope and operable, in response thereto, to supply a plurality of independent variable force feedback signals; and

    a magnetic bearing including a rotor and a plurality of stators, the magnetic bearing rotor coupled to the flight control stick, each magnetic bearing stator disposed adjacent to, and spaced apart from, the magnetic bearing rotor, each magnetic bearing stator coupled to receive one of the independent variable force feedback signals and operable, in response thereto, to supply a variable magnetic feedback force to the magnetic bearing rotor that urges the magnetic bearing rotor in a direction that opposes the displacement direction of the flight control stick.
