Abstract
A method and apparatus for controlling the flight of an aircraft in the event of an in-flight emergency is disclosed. The apparatus includes:
- (a) a remote flight control, located separate and apart from said aircraft, for remote flight control of said aircraft by a remote human pilot;
- (b) an onboard manual flight control on the aircraft for manual flight control of the aircraft by an onboard human pilot;
- (c) an onboard autopilot on the aircraft for automatic flight control of the aircraft;
- (d) a device for detecting an in-flight emergency on board the aircraft, when the onboard pilot is incapable of properly manually flying said first aircraft due to an attack upon the aircraft or its occupants, including its onboard human pilots, or due to any other incapacity of the onboard human pilots, and producing an in-flight emergency signal in response thereto; and
- (e) an onboard remote piloting device on the aircraft for receiving the in-flight emergency control signal and control signals from said remote flight control device and allowing the control of the aircraft by the remote human pilot and preventing flight control by any person on board the aircraft.

-
57. The method of claim 41, wherein said master aircraft control switches from state 2 to state 3 whenever said aircraft control inputs are not received from said onboard piloting means.
-
58. The method of claim 57, wherein said master aircraft control switches from state 3 back to state 2 when said aircraft control inputs are received.
-
59. The method of claim 41, wherein said master aircraft control has a fourth operating state in which none of said sets of aircraft control inputs is output to control the aerodynamic surfaces of said first aircraft, wherein said control unit is placed in said fourth operating state when said first aircraft is on the ground.
