Abstract

A system for aircraft communications comprises an avionics processing unit onboard an aircraft, and a computing platform onboard the aircraft and in operative communication with the avionics processing unit. The computing platform hosts at least one application and one or more aircraft navigational charts with Air Traffic Control (ATC) center identifying information. An aircraft data network is also in operative communication with the computing platform. The avionics processing unit is operative to receive an ATC center facility designator input by a user or from another onboard avionics system, and to transmit the ATC center facility designator to the computing platform. The application is operative to query the aircraft navigational charts based on the ATC center facility designator to obtain corresponding ATC center identifying information, and to send the corresponding ATC center identifying information to the avionics processing unit.

Claims

1. A system for aircraft communications, the system comprising:

an avionics processing unit onboard an aircraft;

a computing platform onboard the aircraft and in operative communication with the avionics processing unit, the computing platform hosting at least one application and one or more aircraft navigational charts with Air Traffic Control (ATC) center identifying information; and

an aircraft data network in operative communication with the computing platform;

wherein the avionics processing unit is operative to;

receive an ATC center facility designator input by a user or from another onboard avionics system; and

transmit the ATC center facility designator to the computing platform;

wherein the at least one application is operative to;

query the one or more aircraft navigational charts based on the ATC center facility designator;

automatically fetch corresponding ATC center identifying information, based on the query, from the one or more aircraft navigational charts; and

send the corresponding ATC center identifying information to the avionics processing unit.

2. The avionics system of claim 1, wherein the avionics processing unit comprises a communications management unit (CMU), a communications management function (CMF), a flight management computer (FMC), a flight management system (FMS), or a flight management function (FMF).

3. The avionics system of claim 1, wherein the computing platform comprises an electronic flight bag (EFB), or an onboard server.

4. The avionics system of claim 1, wherein the one or more aircraft navigational charts comprise sectional charts or digital charts.

5. The avionics system of claim 1, wherein the avionics processing unit is operatively connected to a user interface.

6. The avionics system of claim 1, wherein the ATC center facility designator comprises an aeronautical telecommunications network (ATN) center facility designator, and the ATC center identifying information comprises ATN center information.

7. The avionics system of claim 1, wherein the ATC center facility designator comprises a four character or eight character International Civil Aviation Organization (ICAO) facility designation.

8. The avionics system of claim 1, wherein the ATC center identifying information is used by the avionics processing unit to establish a protected mode-controller pilot data link communications (PM-CPDLC) connection.

9. A method for aircraft communications, the method comprising:

entering an air traffic control (ATC) center facility designator into an avionics processing unit onboard an aircraft;

transmitting the ATC center facility designator from the avionics processing unit to a computing platform onboard the aircraft, the computing platform hosting at least one application and one or more aircraft navigational charts with ATC center identifying information;

querying the navigational charts with the at least one application based on the ATC facility designator;

automatically fetching the ATC center identifying information for a corresponding ATC center name from the navigational charts; and

transmitting the ATC center identifying information from the computing platform to the avionics processing unit.

10. The method of claim 9, further comprising:

establishing a communications connection with an ATC center or air traffic service unit (ATSU) corresponding to the ATC center identifying information.

11. The method of claim 10, wherein the communications connection comprises a protected mode-controller pilot data link communications (PM-CPDLC) connection.

12. The method of claim 9, wherein the one or more aircraft navigational charts comprise sectional charts or digital charts.

13. The method of claim 9, wherein the ATC center facility designator comprises an aeronautical telecommunications network (ATN) center facility designator, and the ATC center identifying information comprises ATN center information.

14. The method of claim 9, wherein the ATC center facility designator comprises a four character or eight character International Civil Aviation Organization (ICAO) facility designation.

15. The method of claim 9, wherein the computing platform comprises an electronic flight bag (EFB), or an onboard server.

16. A computer program product comprising:

a non-transitory computer readable medium having instructions stored thereon executable by a processor to perform a method for aircraft communications, the method comprising;

entering an air traffic control (ATC) center facility designator into an avionics processing unit onboard an aircraft;

transmitting the ATC center facility designator from the avionics processing unit to a computing platform onboard the aircraft, the computing platform hosting at least one application and one or more aircraft navigational charts with ATC center identifying information;

querying the navigational charts with the at least one application based on the ATC facility designator;

automatically fetching the ATC center identifying information for a corresponding ATC center name from the navigational charts; and

transmitting the ATC center identifying information from the computing platform to the avionics processing unit.

17. The computer program product of claim 16, wherein the method further comprises:

establishing a communications connection with an ATC center or air traffic service unit (ATSU) corresponding to the ATC center identifying information.

18. The computer program product of claim 17, wherein the communications connection comprises a protected mode-controller pilot data link communications (PM-CPDLC) connection.

19. The computer program product of claim 16, wherein the ATC center facility designator comprises an aeronautical telecommunications network (ATN) center facility designator, and the ATC center identifying information comprises ATN center information.

20. The computer program product of claim 16, wherein the ATC center facility designator comprises a four character or eight character International Civil Aviation Organization (ICAO) facility designation.
