Abstract

An avionics system comprising a human machine interface configured to display a user interface and a control device is provided. The control device coupled to the human machine interface, wherein the control device is configured to send and receive controller/pilot data link communications (CPDLC) messages and adjust the user interface based on a first CPDLC version of an established first CPDLC session.

Claims

1. An avionics system comprising:

a human machine interface configured to display a user interface; and

a control device coupled to the human machine interface, wherein the control device is configured to;

send and receive controller/pilot data link communications (CPDLC) messages;

send a logon message to an air traffic control center;

receive a logon response message sent from the air traffic control center, the logon response message sent upon a successful logon to the air traffic control center in response to the logon message, the logon response message specifying a first CPDLC version that a current data authority supports; and

adjust the user interface based on the first CPDLC version specified in the logon response message.

2. The avionics system of claim 1, wherein the human machine interface further comprises:

a display device for a displaying a logical screen corresponding to the user interface; and

an input device configured to allow a user to interact with the user interface; and

wherein the logical screen displays a user preference option for selecting a CPDLC version logon sequence preference from a plurality of CPDLC version login sequence preferences, and wherein the control device selects between sending a logon message for the first CPDLC version and sending a logon message for a second CPDLC version based on the CPDLC version logon sequence preference.

3. The avionics system of claim 2, wherein the logical screen comprises at least one of a logon page and a message selection page.

4. The avionics system of claim 3, wherein the at least one logon page further comprises an option for selecting an air traffic control center to log into from a plurality of available air traffic control centers.

5. The avionics system of claim 1, wherein the first CPDLC version further comprises a first CPDLC version of a first ground station to which the avionics system is logged into.

6. The avionics system of claim 1, wherein the control device is further configured to indicate that an unsupported message is not supported by the first CPDLC version.

7. The avionics system of claim 6, wherein the control device is configured to indicate that an unsupported message is not supported by the first CPDLC version and is further configured to one of remove a selection prompt for the unsupported message, gray out the unsupported message, fade the color of the unsupported message, change the color of the unsupported message, and remove the unsupported message from the page.

8. The avionics system of claim 1, wherein the display device is further configured to display an indication of the first CPDLC version.

9. The avionics system of claim 1, wherein the control device is further configured to:

establish a second CPDLC session with a second ground station, wherein the second ground station supports a second CPDLC version; and

adjust the one or more pages based on the second CPDLC version.

10. The avionics system of claim 1, wherein the control device is one of a flight management computer and a communication management unit.

11. A method of providing a user interface for a Controller/Pilot Data Link Communication (CPDLC), comprising:

receiving a logon response message sent from an air traffic control center, the logon response message sent upon a successful logon to the air traffic control center in response to a logon message, the logon response message specifying that the current data authority supports a first CPDLC version; and

adjusting an output of the user interface based on the first CPDLC version specified in the logon response message.

12. The method of claim 11, further comprising adjusting a ground station user interface based on the first CPDLC version.

13. The method of claim 11, further comprising:

displaying a user preference option on the user interface for selecting a CPDLC version logon sequence preference from a plurality of CPDLC version login sequence preferences, and

selecting between sending a logon message for the first CPDLC version and sending a logon message for a second CPDLC version based on the CPDLC version logon sequence preference.

14. The method of claim 13, further comprising:

wherein the logon message contains an indication of a preferred CPDLC version; and

wherein a CPDLC session of the preferred CPDLC version is established when a connection is established with the current data authority that supports the preferred CPDLC version.

15. The method of claim 11, further comprising:

determining a second CPDLC version of a second data authority;

establishing a CPDLC session of the second CPDLC version with the second data authority; and

adjusting the output of the display device based on the second CPDLC version.

16. The method of claim 11, wherein adjusting an output of the display device based on the second CPDLC version further comprises indicating that an unsupported message is not supported by the first CPDLC version.

17. The method of claim 16, wherein indicating that an unsupported message is not supported by the first CPDLC version further comprises one of removing a selection prompt for the unsupported message, graying out the unsupported message, fading the color of the unsupported message, changing the color of the unsupported message, and removing the unsupported message from the page.

18. A program product comprising a non-transitory processor-readable medium on which program instructions are embodied, wherein the program instructions are operable, when executed by at least one programmable processor, to cause the at least one programmable processor to:

determine a first Controller Pilot Data Link Communication (CPDLC) version from a logon response message received from a first air traffic control (ATC) center, the logon response message sent upon a successful logon to the air traffic control center in response to a logon message and including the first CPDLC version; and

provide instructions to a human machine interface to display a first page where only messages supported by the first CPDLC version are selectable.

19. The program product of claim 18, wherein provide instructions to the human machine interface further comprises display an indication the first CPDLC version.

20. The program product of claim 18, further comprising:

determine a second CPDLC version of a second ATC center;

establish a CPDLC session of the second CPDLC version with the second ATC center; and

provide instructions to the human machine interface to display a second page where only messages supported by the second CPDLC version are selectable.
