Abstract

A method for operating an aircraft includes the steps of receiving guidance instructions and guidance parameters at a navigation computer, and transmitting automatic pilot instructions from the navigation computer to a flight control computer. The method also includes the steps of receiving control instructions and the automatic pilot instructions at the flight control computer, and generating operating commands at the flight control computer. In an automatic pilot mode, the operating commands are generated at the flight control computer based on the automatic pilot instructions.

Claims

1. A method for operating an aircraft, comprising the steps of:

receiving guidance instructions and guidance parameters at a navigation computer;

transmitting automatic pilot instructions from said navigation computer to a flight control computer over a dedicated communication link;

receiving control instructions and said automatic pilot instructions at said flight control computer;

in an automatic pilot mode, generating a first plurality of operating commands based on said automatic pilot instructions at said flight control computer; and

in a manual pilot mode, generating a second plurality of operating commands based on said control instructions at said flight control computer.

2. The method of claim 1, further comprising the step of receiving control parameters at said flight control computer.

3. The method of claim 2, wherein the step of receiving control parameters at said flight control computer comprises receiving said control parameters via an input different from both an input through which said control instructions are received and an input through which said automatic pilot instructions are received.

4. The method of claim 1, further comprising the step of generating said automatic pilot instructions at said navigation computer based on said guidance instructions and on said guidance parameters.

5. The method of claim 4, wherein said automatic pilot instructions correspond in nature to said control instructions.

6. The method of claim 5, wherein said automatic pilot instructions and said control instructions correspond to a commanded vertical load factor.

7. The method of claim 5, wherein said automatic pilot instructions and said control instructions correspond to a commanded roll rate.

8. The method of claim 5, wherein said automatic pilot instructions and said control instructions correspond to a commanded yaw.

9. The method of claim 1, further comprising the step of transmitting said first plurality of operating commands from said flight control computer to a plurality of control surfaces.

10. The method of claim 9, further comprising the step of receiving inertial information at said navigation computer.

11. The method of claim 10, wherein a delay between a time at which said inertial information is received at said navigation computer and a time at which said first plurality of operating commands is transmitted from said flight control computer to said plurality of control surfaces is minimized.

12. A method for operating an aircraft, comprising the steps of:

transmitting automatic pilot instructions from a navigation computer to a flight control computer over a dedicated communication link;

receiving control instructions and said automatic pilot instructions at said flight control computer;

in an automatic pilot mode, generating a first plurality of operating commands based on said automatic pilot instructions at said flight control computer; and

in a manual pilot mode, generating a second plurality of operating commands based on said control instructions at said flight control computer.
