Abstract

A method and corresponding system remotely communicate and interface with an Aircraft Condition Monitoring System (ACMS) on an aircraft. The method and system offer a global communication architecture that can be implemented with existing ACMS devices and with any flight data acquisition unit (FDAU) equipped with a storage card, such as a Personal Computer Memory Card. International Association (PCMCIA) card. In a preferred embodiment, the method and system offer real-time wireless communication between the ACMS on an aircraft and a ground station without any hardware and/or software modifications to the ACMS.

Claims

1. A computer-implemented method for remotely communicating and interfacing with an aircraft condition monitoring system (ACMS) on an aircraft, comprising:

providing a storage card with a process that has processing power and wireless transmission functionality, the storage card including a wireless interface;

plugging the storage card into the ACMS using a card interface, wherein the ACMS collects flight performance data and generates an ACMS report after one or more exclusive conditions are fulfilled, wherein the one or more exclusive conditions are selected from a group consisting of opening of cargo doors of the aircraft, a ground speed of the aircraft reaching zero, an engine fuel flow reaching zero, and closing of fuel valves of the aircraft;

using the processor embedded in the storage card to detect whether the ACMS report is generated;

after the one or more exclusive conditions are fulfilled and the ACMS report is generated, connecting the wireless interface to a ground-based network based on network attributes stored in a database on the storage card; and

automatically and wirelessly transmitting the flight performance data to a ground station through a wireless network.

2. The method of claim 1, further comprising determining whether there is a connection available between the storage card and the ground station.

3. The method of claim 1, wherein the providing step includes providing a personal computer memory card international association (PCMCIA) card with the processor that has processing power and wireless transmission functionality.

4. The method of claim 1, further comprising erasing the flight performance data from the storage card after the transmission.

5. The method of claim 1, further comprising employing security measures to secure an access to the flight performance data.

6. The method of claim 5, wherein the employing step includes encrypting the flight performance data during transmission.

7. The method of claim 5, wherein the employing step includes employing wired equivalent privacy (WEP) during transmission.

8. The method of claim 5, wherein the employing step includes employing wireless-fidelity protected access (WPA) during transmission.

9. The method of claim 5, wherein the employing step includes employing advanced encryption standard (AES) during transmission.

10. The method of claim 5, wherein the employing step includes employing extensible authentication protocol (EAP) during transmission.

11. The method of claim 1, wherein the wirelessly transmitting step includes wirelessly transmitting the flight performance data to a ground-based network through a wireless-fidelity (Wi-Fi) 802.11b network.

12. The method of claim 1, wherein using the processor step includes using the processor to check that the ACMS report triggered by opening of cargo doors of the aircraft is present on a memory of the storage card.

13. The method of claim 1, wherein using the processor step includes using the processor to check that the ACMS report triggered by a ground speed of the aircraft reaching zero is present on a memory of the storage card.

14. The method of claim 1, wherein using the processor step includes using the processor to check that the ACMS report triggered by an engine fuel flow reaching zero is present on a memory of the storage card.

15. The method of claim 1, wherein using the processor step includes using the processor to check that the ACMS report triggered by closing of fuel valves of the aircraft is present on a memory of the storage card.

16. The method of claim 1, further comprising remotely accessing the ACMS and ACMS peripherals from the ground station.

23. The method of claim 1, wherein the wirelessly transmitting step includes wirelessly transmitting the flight performance data to a ground-based network through a wireless-fidelity (Wi-Fi) 802.11a network.

24. The method of claim 1, wherein the wirelessly transmitting step includes wirelessly transmitting the flight performance data to a ground-based network through a wireless-fidelity (Wi-Fi) 802.11g network.

25. The method of claim 1, wherein the wirelessly transmitting step includes wirelessly transmitting the flight performance data to a ground-based network through a wireless-fidelity (Wi-Fi) 802.16 network.

17. A computer-implemented method for remotely communicating and interfacing with an aircraft condition monitoring system (ACMS) on an aircraft, comprising:

providing a storage card with a processor that has processing power and wired transmission functionality;

plugging the storage card into the ACMS using a card interface, wherein the ACMS collects flight performance data and generates an ACMS report after one or more exclusive conditions are fulfilled, wherein the one or more exclusive conditions are selected from a group consisting of opening of cargo doors of the aircraft, a ground speed of the aircraft reaching zero, an engine fuel flow reaching zero, and closing of fuel valves of the aircraft;

using the processor embedded in the storage card to detect whether the ACMS report is generated;

using an access point to establish a connection with a ground-based network through a wireless network;

after the one or more exclusive conditions are fulfilled and the ACMS report is generated, determining whether there is a connection available between the storage card and a ground station; and

automatically transmitting the flight performance data to the ground station through the available connection.

18. The method of claim 17, wherein the wired network is an Ethernet.

19. The method of claim 17, further comprising erasing the flight performance data from the storage card after the transmission.

20. The method of claim 17, further comprising employing security measures to secure an access to the flight performance data.

21. The method of claim 17, wherein the wirelessly transmitting step includes wirelessly transmitting the flight performance data to a ground-based network through a wireless-fidelity (Wi-Fi) 802.11b network.

22. The method of claim 17, further comprising remotely accessing the ACMS and ACMS peripherals from the ground station.
