Abstract

A system for automated fault analysis and execution of post-flight or pre-flight tests for an aircraft is provided. The system includes a maintenance test client system onboard the aircraft, and a ground-based maintenance test server system that is remote from the aircraft. The maintenance test client system is configured to collect fault data for the aircraft, and to wirelessly transmit the fault data to the ground-based maintenance test server system after the aircraft has landed. The ground-based maintenance test server system is configured to receive the fault data, to generate a test checklist that is influenced by the fault data, and to transmit the test checklist to the maintenance test client system. The maintenance test client system wirelessly receives the test checklist, and initiates execution of at least one test specified in the test checklist.

Claims

1. A method of automated fault analysis and execution of post-flight or pre-flight tests for an aircraft having an onboard maintenance test client system, the method comprising:

establishing a data communication session with the onboard maintenance test client system after the aircraft has landed, the data communication session using at least one wireless data communication link;

receiving, at a ground-based maintenance test server system, diagnostic data from the onboard maintenance test client system during the data communication session;

thereafter, generating a test checklist for the aircraft, wherein content of the test checklist is influenced by the diagnostic data, and wherein the test checklist is generated by the ground-based maintenance test server system;

thereafter, transmitting the test checklist from the ground-based maintenance test server system to the onboard maintenance test client system during the data communication session;

thereafter, receiving a test report at an air traffic control system, the test report comprising results of maintenance tests specified on the test checklist, wherein the maintenance tests are performed onboard the aircraft in response to receiving the test checklist from the ground-based maintenance test server system;

reviewing the test report at the air traffic control system to determine that the aircraft is flight worthy;

in response to determining that the aircraft is flight worthy, sending an approval message from the air traffic control system to an airlines operations center; and

in response to the approval message, sending a takeoff approval message from the airlines operations center to the onboard maintenance test client system.

2. The method of claim 1, further comprising the step of preparing a fault analysis report from the diagnostic data.

3. The method of claim 2, further comprising the step of sending the fault analysis report to a maintenance personnel terminal.

4. The method of claim 2, further comprising the step of sending the fault analysis report to an airlines operations center.

5. The method of claim 1, wherein receiving diagnostic data comprises receiving a takeoff checklist fault report, an en route checklist fault report, or a landing checklist fault report.

6. The method of claim 1, wherein receiving diagnostic data comprises receiving central maintenance computing function (CMCF) fault information.

7. The method of claim 1, further comprising the step of storing the diagnostic data at a location remote from the aircraft.

8. The method of claim 1, wherein content of the test checklist is influenced by the characteristics of the aircraft.

9. The method of claim 1, wherein content of the test checklist is influenced by an airline associated with the aircraft.

10. A method of automated fault analysis and execution of post-flight or pre-flight tests for an aircraft, the method comprising:

establishing a data communication session between an onboard maintenance test client system and a ground-based system after the aircraft has landed, the data communication session using at least one wireless data communication link;

sending diagnostic data from the onboard maintenance test client system to the ground-based system during the data communication session;

thereafter, obtaining a test checklist for the aircraft from the ground-based system, wherein content of the test checklist is influenced by the diagnostic data, and wherein the test checklist is obtained at the onboard maintenance test client system; and

thereafter, completing at least one test specified in the test checklist, and generating an associated test report;

providing the test report to an air traffic control system;

reviewing the test report at the air traffic control system to determine that the aircraft is flight worthy;

in response to determining that the aircraft is flight worthy, sending an approval message from the air traffic control system to an airlines operations center; and

in response to the approval message, sending a takeoff approval message from the airlines operations center to the onboard maintenance test client system.

11. The method of claim 10, wherein sending diagnostic data comprises sending a takeoff checklist fault report, an en route checklist fault report, or a landing checklist fault report.

12. The method of claim 10, wherein sending diagnostic data comprises sending central maintenance computing function (CMCF) fault information.

13. The method of claim 10, wherein the step of completing at least one test comprises automatically executing the at least one test onboard the aircraft, without human intervention during execution.

14. The method of claim 10, wherein the step of completing at least one test comprises executing the at least one test onboard the aircraft, with human interaction during execution.

15. The method of claim 10, further comprising:

establishing an interactive control session with a remote maintenance personnel terminal; and

controlling, with the remote maintenance personnel terminal, execution of the at least one test.

16. A system for automated fault analysis and execution of post-flight or pre-flight tests for an aircraft, the system comprising:

a maintenance test client system onboard the aircraft; and

a ground-based maintenance test server system that is remote from the aircraft;

an air traffic control system; and

an airlines operations center;

the maintenance test client system being configured to collect fault data for the aircraft, and to wirelessly transmit the fault data to the ground-based maintenance test server system after the aircraft has landed;

the ground-based maintenance test server system being configured to receive the fault data, to generate a test checklist that is influenced by the fault data, and to transmit the test checklist to the maintenance test client system;

the maintenance test client system being further configured to wirelessly receive the test checklist, to initiate execution of at least one test specified in the test checklist, and to generate a test report that includes results of the at least one test specified in the test checklist;

the maintenance test client system being further configured to provide the test report to the air traffic control system;

the air traffic control system being configured to review the test report to determine that the aircraft is flight worthy, and to send an approval message to the airlines operations center; and

the airlines operation center being configured to respond to the approval message by sending a takeoff approval message to the onboard maintenance test client system.

17. The system of claim 16, further comprising line replaceable units (LRUs) onboard the aircraft, wherein the maintenance test client system cooperates with the LRUs to execute the at least one test.

18. The system of claim 17, wherein the maintenance test client system and the LRUs automatically execute the at least one test onboard the aircraft, without human intervention during execution.

19. The system of claim 16, further comprising a maintenance personnel terminal that is remote from the aircraft, wherein the maintenance test client system establishes an interactive control session with the maintenance personnel terminal, and wherein the maintenance personnel terminal is configured to remotely control execution of the at least one test.
