A method and system for preventing the control of an aircraft from the cockpit. In an exemplary embodiment, the system could be triggered externally. For example, an air traffic control (ATC) station could determine that the aircraft has deviated from its planned flight path. If personnel at the ATC station decide that the deviation is not attributable to the actions of the authorized flight crew, the personnel can transmit a signal to the aircraft that disables all normal cockpit control of the aircraft. Once normal flight controls are disabled, the aircraft may execute a preprogrammed emergency flight plan via its autopilot system, with or without the use of a flight management system (FMS). The emergency flight plan could cause the aircraft to fly to a sparsely populated area and enter a holding pattern, or it could cause the aircraft to land in a sparsely populated area or at an airport using an autoland system.

I claim: 1. A method for controlling an aircraft, comprising: receiving a first trigger; disabling cockpit control of the aircraft in response to the first trigger; and enabling a special reversionary mode to control the aircraft in response to the first trigger; wherein the first trigger is based on the aircraft's deviation from a planned flight path. 2. The method of claim 1, further comprising: generating the first trigger, wherein the first trigger is generated outside the aircraft. 3. The method of claim 1, wherein the first trigger is generated within the aircraft. 4. The method of claim 3, wherein the first trigger is generated without human input. 5. The method of claim 3, wherein the first trigger is generated using human input. 6. The method of claim 2, wherein the first trigger comprises an encrypted signal. 7. The method of claim 1, further comprising: sensing a triggering event; and generating the first trigger in response to the event. 8. The method of claim 1, further comprising: receiving a second trigger subsequent to receiving the first trigger; re-enabling cockpit control of the aircraft in response to receiving the second trigger. 9. A method for controlling an aircraft, comprising: sensing a first triggering event; generating a first trigger in response to the first triggering event; receiving the first trigger; disabling cockpit control of the aircraft in response to the first trigger; wherein the first triggering event is based on a sudden maneuver of the aircraft; and enabling a special reversionary mode to control the aircraft in response to the first trigger. 10. Apparatus for controlling an aircraft, comprising: an activator for generating an activation trigger; and a switch communicatively coupled to the activator, the switch disabling cockpit control of the aircraft in response to the activation trigger, the activation trigger further enabling a special reversionary mode, wherein the special reversionary mode comprises entering into a predefined flight path. 11. The apparatus of claim 10, wherein the special reversionary mode causes the aircraft to execute a safe, pre-programmed flight path. 12. The apparatus of claim 10, wherein the activator comprises a transceiver that receives a signal from outside the aircraft and responsively generates the activation trigger. 13. The apparatus of claim 10, wherein the activator comprises a manually activated switch onboard the aircraft. 14. The apparatus of claim 13, wherein the manually activated switch comprises at least one keypad. 15. The apparatus of claim 10, wherein the activator comprises a flight path sensor. 16. The apparatus of claim 12, wherein the signal is encrypted. 17. The apparatus of claim 10, further comprising: a deactivator for generating a deactivation trigger; wherein the switch is communicatively coupled to the deactivator, the switch re-enabling cockpit control of the aircraft in response to receiving the deactivation trigger; and wherein the deactivation trigger also disables the special reversionary mode. 18. The apparatus of claim 17, wherein the deactivator comprises a manually activated switch onboard the aircraft. 19. The apparatus of claim 18, wherein the manually activated switch comprises at least one keypad. 20. The apparatus of claim 17, wherein the deactivator comprises a sensor that indicates the aircraft has landed. 21. A method for controlling an aircraft, comprising: receiving a first trigger; disabling cockpit control of the aircraft in response to the first trigger; and enabling a special reversionary mode to control the aircraft in response to the first trigger; wherein the first trigger is based on a cabin air pressure sensor or a vibration sensor. 22. The method of claim 21, wherein the special reversionary mode comprises entering into a predefined flight path. 23. The method of claim 22, wherein the special reversionary mode causes the aircraft to execute a safe, pre-programmed flight path. 24. The method of claim 1, wherein the special reversionary mode comprises entering into a predefined flight path. 25. The method of claim 24, wherein the special reversionary mode causes the aircraft to execute a safe, pre-programmed flight path. 26. The method of claim 9, wherein the special reversionary mode comprises entering into a predefined flight path. 27. The method of claim 26, wherein the special reversionary mode causes the aircraft to execute a safe, pre-programmed flight path.
