Abstract

A system for operating an aircraft includes a navigation computer and a flight control computer. The navigation computer receives guidance instructions and guidance parameters, and outputs automatic pilot instructions. The flight control computer receives control instructions and the automatic pilot instructions, and generates operating commands based on the automatic pilot instructions in an automatic pilot mode.

Claims

1. A system for operating an aircraft, comprising:

a navigation computer comprising;

a first input configured to receive guidance instructions including heading, vertical speed, and altitude,

a second input configured to receive guidance parameters, and

an output configured to output automatic pilot instructions computed by said navigation computer from said guidance instructions;

a flight control computer comprising;

a first input configured to receive control instructions,

a second input configured to receive said automatic pilot instructions, and

a command generator configured to generate a first plurality of operating commands based on said automatic pilot instructions in an automatic pilot mode; and

a dedicated communication link configured to transmit the automatic pilot instructions from the navigation computer to the flight control computer,

wherein said automatic pilot instructions correspond in nature to said control instructions.

2. The system of claim 1, wherein said command generator is configured to generate a second plurality of operating commands based on said control instructions in a manual pilot mode.

3. The system of claim 1, wherein said flight control computer further comprises a third input configured to receive control parameters.

4. The system of claim 1, wherein said command generator is configured to generate said first and second pluralities of operating commands based on a single control function.

5. The system of claim 4, wherein said single control function is embedded in said flight control computer.

6. The system of claim 1, wherein said navigation computer generates said automatic pilot instructions based on said guidance instructions and on said guidance parameters.

7. The system of claim 1, wherein said automatic pilot instructions and said control instructions correspond to a commanded vertical load factor.

8. The system of claim 1 wherein said automatic pilot instructions and said control instructions correspond to a commanded roll rate.

9. The system of claim 1, wherein said automatic pilot instructions and said control instructions correspond to a commanded yaw.

10. A system for operating an aircraft, comprising:

a navigation computer comprising;

means for receiving guidance instructions including heading, vertical speed, and altitude,

means for receiving guidance parameters, and

means for outputting automatic pilot instructions computed by said

navigation computer from said guidance instructions;

a flight control computer comprising;

means for receiving control instructions,

means for receiving said automatic pilot instructions, and

means for generating a first plurality of operating commands based on said

automatic pilot instructions in an automatic pilot mode; and

dedicated communication means for transmitting the automatic pilot instructions from

the navigation computer to the flight control computer,

wherein said automatic pilot instructions correspond in nature to said control instructions.

11. The system of claim 10, wherein said flight control computer further comprises means for generating a second plurality of operating commands based on said control instructions in a manual pilot mode.

12. The system of claim 10, wherein said flight control computer further comprises means for receiving control parameters.

13. The system of claim 10, wherein said first and second pluralities of operating commands are based on a single control function.

14. The system of claim 13, wherein said single control function is embedded in said flight control computer.

15. The system of claim 10, wherein said navigation computer further comprises means for generating said automatic pilot instructions based on said guidance instructions and on said guidance parameters.

16. The system of claim 15, wherein said automatic pilot instructions correspond to a commanded vertical load factor, commanded roll rate, and a commanded yaw.

17. The system of claim 16, wherein said control instructions correspond to a commanded vertical load factor, commanded roll rate, and a commanded yaw.

18. A system for operating an aircraft, comprising:

a navigation computer configured to receive guidance instructions and parameters, and to output automatic pilot instructions;

a flight control computer configured to receive control instructions and said automatic pilot instructions, and to generate a first plurality of operating commands based on said automatic pilot instructions in an automatic pilot mode; and

a dedicated communication link configured to transmit the automatic pilot instructions from the navigation computer to the flight control computers

wherein said automatic pilot instructions correspond in nature to said control instructions.

19. The system of claim 18, wherein said flight control computer is configured to generate a second plurality of operating commands based on said control instructions in a manual pilot mode.

20. The system of claim 18, wherein said flight control computer further comprises a third input configured to receive control parameters.

21. The system of claim 18, wherein said flight control computer is configured to generate said first and second pluralities of operating commands based on said single control function.

22. The system of claim 18, wherein said navigation computer generates said automatic pilot instructions based on said guidance instructions and on said guidance parameters.

23. The system of claim 18, wherein said automatic pilot instructions and said control instructions correspond to a commanded vertical load factor.

24. The system of claim 18, wherein said automatic pilot instructions and said control instructions correspond to a commanded roil rate.

25. The system of claim 18, wherein said automatic pilot instructions and said control instructions correspond to a commanded yaw.
