Abstract

Embodiments for detecting when a datalink application is available at an airport are disclosed. In one embodiment, an avionics computer installed onboard an aircraft comprises: a processing device; and a memory device communicatively coupled to the processing device and including instructions which, when executed by the processing device, cause the processing device to: send a request to a datalink applications database, wherein the request includes a query as to whether an airport is equipped with at least one datalink application; receive a response from the datalink applications database, wherein the response indicates whether the airport is equipped with the at least one datalink application; and send a message via datalink if the response indicates the airport is equipped with the at least one datalink application.

Claims

1. An avionics computer installed onboard an aircraft, the avionics computer comprising:

a processing device; and

a memory device communicatively coupled to the processing device and including instructions which, when executed by the processing device, cause the processing device to;

send a request to a datalink applications database, wherein the request includes a query as to whether an airport is equipped with at least one datalink application that can be communicated via datalink;

receive a response from the datalink applications database, wherein the response indicates whether the airport is equipped with the at least one datalink application; and

when the response indicates the airport is equipped with the at least one datalink application, send a message via datalink requesting the at least one datalink application that the airport is equipped with.

2. The avionics computer of claim 1, wherein the datalink applications database is external to the aircraft.

3. The avionics computer of claim 1, wherein the datalink applications database is stored in the aircraft'"'"'s electronic flight bag.

4. The avionics computer of claim 1, wherein the at least one datalink application includes at least one of the following:

departure clearance (DCL) information, D-TAXI information, Future Air Navigation System (FANS) information, Flight Information Service (FIS) information, Controller Pilot Data Link Communication (CPDLC); and

wherein when the at least one application includes DCL information, the response includes an address where the DCL request is to be sent.

5. The avionics computer of claim 1, wherein the avionics computer is incorporated into the flight management computer (FMC) of the aircraft or the Communications Management Unit (CMU) of the aircraft.

6. The avionics computer of claim 1, wherein the processing device is configured to automatically send the request when the aircraft lands at the airport.

7. The avionics computer of claim 1, wherein the processing device is configured to automatically send the request when the aircraft parks in the gate at the airport.

8. The avionics computer of claim 1, wherein the processing device is configured to send the request when a flight crew member directs the avionics computer to do so.

9. A method for determining whether an airport is equipped with at least one datalink application, the method comprising:

sending a request from an avionics computer onboard an aircraft to a datalink applications database as to whether an airport is equipped with at least one datalink application that can be communicated via datalink;

receiving a response from the datalink applications database as to whether the airport is equipped with the at least one datalink application;

when the response indicates the airport is equipped with the at least one datalink application, sending a message via datalink requesting the at least one datalink application that the airport is equipped with.

10. The method of claim 9, wherein the datalink applications database is external to the aircraft.

11. The method of claim 9, wherein the datalink applications database is stored in the aircraft'"'"'s electronic flight bag.

12. The method of claim 9, wherein the at least one datalink application includes at least one of the following:

departure clearance (DCL) information, D-TAXI information, Future Air Navigation System (FANS) information, Flight Information Service (FIS) information, Controller Pilot Data Link Communication (CPDLC); and

wherein when the at least one application includes DCL information, the response includes an address where the DCL request is to be sent.

13. The method of claim 9, wherein sending the request to the datalink applications database is automatically performed when the aircraft lands at the airport.

14. The method of claim 9, wherein sending the request to the datalink applications database is automatically performed when the aircraft parks in its gate at the airport.

15. The method of claim 9, wherein sending the request to the datalink applications database is initiated by a flight crew member.

16. An avionics system comprising:

a datalink applications database, wherein the datalink applications database has a list of airports that are equipped with at least one datalink application;

an avionics computer installed onboard an aircraft and configured to send a request to the datalink applications database and receive a response from the datalink applications database,

wherein the request includes a query as to whether an airport is equipped with at least one datalink application that can be communicated via datalink; and

wherein the response indicates whether the airport is equipped with the at least one datalink application; and

wherein when the response indicates the airport is equipped with the at least one datalink application, send a request for the datalink application via datalink.

17. The avionics system of claim 16, wherein the datalink applications database is external to the aircraft.

18. The avionics system of claim 16, wherein the datalink applications database is stored in the aircraft'"'"'s electronic flight bag.

19. The avionics system of claim 16, wherein the avionics computer is incorporated into the flight management computer (FMC) of the aircraft or the Communications Management Unit (CMU) of the aircraft.

20. The avionics system of claim 16, wherein the at least one datalink application includes at least one of the following:

departure clearance (DCL) information, D-TAXI information, Future Air Navigation System (FANS) information, Flight Information Service (FIS) information, Controller Pilot Data Link Communication (CPDLC); and

wherein when the at least one application includes DCL information, the response includes an address where the DCL request is to be sent.
