Abstract

Control systems and methods of use provide for fully automated phases of flight of an aircraft. Such fully automated phases include takeoff, cruising flight, and landing without the need for operator input or other operator intervention. Control systems and methods also provide for self-limited compliance with an operators desired deviation from a predetermined flight path, as well as automatic contingency response to non-normal conditions. Onboard and/or ground-based operators may cooperate with the control system in order to control the associated aircraft. Furthermore, an operator need not have any flight skill in order to affect changes in the flight path or other aspects of flight control.

Claims

1. A computer-based method to automatically manage flight operations of a manned aircraft, comprising:

receiving, in a computer-based flight control system, a destination for a flight;

determining, in the computer-based flight control system, a predetermined flight path and one or more flight parameters to the destination;

navigating an aircraft along the predetermined flight path using autopilot controls;

receiving, in the computer-based flight control system, operator input from an operator interface to direct the aircraft along a flight path segment which deviates from the predetermined flight path by overriding the autopilot controls;

generating, in the computer-based flight control system, one or more control signals to direct the aircraft from the predetermined flight path to the flight path segment which deviates from the predetermined flight path;

generating, in the computer-based flight control system, one or more feedback signals to provide force feedback against control instructions from the operator interface when the control instructions attempt to navigate the aircraft along a flight path segment which deviates from the predetermined flight path, wherein the force feedback indicates that further deviation from the predetermined flight path will not be permitted; and

directing the aircraft to resume travel along the predetermined flight path despite the receiving the operator input from the operator interface when a distance of the aircraft from the predetermined flight path exceeds a permitted deviation distance.

2. The method of claim 1, wherein the force feedback is proportional to a distance of the aircraft from the predetermined flight path.

3. The method of claim 2, wherein the force feedback increases as a distance of the aircraft from the predetermined flight path increases.

4. The method of claim 3, wherein the operator interface is located within the aircraft.

5. The method of claim 1 wherein the permitted deviation distance is based on at least one of a no fly zone and a fuel-based limitation.

6. The method of claim 1, wherein the operator interface is a control stick.

7. A computer-based method to automatically manage flight operations of a manned aircraft, comprising:

receiving, in a computer-based flight control system, a destination for a flight;

determining, in the computer-based flight control system, a predetermined flight path and one or more flight parameters to the destination;

navigating an aircraft along the predetermined flight path using autopilot controls;

receiving, in the computer-based flight control system, a control signal via an operator interface to direct an aircraft along a flight path segment which deviates from the predetermined flight path by overriding the autopilot controls;

generating, in the computer-based flight control system, one or more control signals to direct the aircraft from the predetermined flight path to the flight path segment which deviates from the predetermined flight path in response to the received pressure;

generating, in the computer-based flight control system, one or more feedback signals to provide force feedback against the operator interface when the aircraft is directed along a flight path segment which deviates from the predetermined flight path, wherein the force feedback indicates that further deviation from the predetermined flight path will not be permitted; and

directing the aircraft to resume travel along the predetermined flight path upon a termination of the received control signals; and

directing the aircraft to resume travel along the predetermined flight path despite the receiving the operator input from the operator interface when a distance of the aircraft from the predetermined flight path exceeds a permitted deviation distance.

8. The method of claim 7, wherein the force feedback is proportional to a distance of the aircraft from the predetermined flight path.
