Abstract

A method of displaying information pertaining to an air vehicle is disclosed. Information is displayed indicative of first portions of a map where distance between a current altitude of the air vehicle and terrain in the map are within a first threshold. Information is displayed indicative of second portions of a map where a distance between the current altitude of the air vehicle and terrain in the map are within a second threshold. The first and second portions are updated based on a change in the current altitude of the air vehicle. In another example, a map including a projected flight path of an aircraft is displayed. Location-based information pertaining to radio frequency (RF) status between the aircraft and at least one ground radio is displayed on the map. The location-based information pertaining to RF status is updated based on a change in the current position of the air vehicle.

First claim

What is claimed:

1. A method of displaying information about an air vehicle, the method comprising:
displaying, on a user interface operable to allow a controller to remotely interact with the air vehicle, a map including a projected flight path of the air vehicle;
displaying, on the map, location-based information pertaining to radio frequency (RF) status between the air vehicle and at least one ground radio; and
updating the location-based information pertaining to RF status based on a change in a current position of the air vehicle.

2. The method of claim 1 , wherein the location-based information are indicative of one or more of antenna pattern, gain, type, and power capabilities.

3. The method of claim 1 , wherein the RF status is determined by comparing predicted signal strength of RF links of an area on the map to signal strength corresponding to lost communication and determining if the area on the map will likely experience lost communication.

4. The method of claim 1 , wherein the location-based information comprises RF link error rate.

5. The method of claim 1 , wherein displaying a map comprises displaying a fixed size portion of the display, said fixed size portion representing a predetermined area on the map.

6. The method of claim 5 , wherein said fixed size portion is a tile and is color coded to indicate an estimated strength of an RF link.

7. A system configured to display information pertaining to an air vehicle, the system comprising:
at least one memory having stored therein computer instructions that, upon execution by one or more processors of the system, at least cause the system to:
display, on a user interface operable to allow a controller to remotely interact with the air vehicle, a map including a projected flight path of the air vehicle;
display, on the map, location-based information pertaining to radio frequency (RF) status between the air vehicle and at least one ground radio; and
update the location-based information pertaining to RF status based on a change in a current position of the air vehicle.

8. The system of claim 7 , wherein the location-based information are indicative of one or more of antenna pattern, gain, type, and power capabilities.

9. The system of claim 7 , wherein the RF status is determined by comparing predicted signal strength of RF links of an area on the map to signal strength corresponding to lost communication and determining if the area on the map will likely experience lost communication.

10. The system of claim 7 , wherein the location-based information comprises RF link error rate.

11. The system of claim 7 , wherein displaying a map comprises displaying a fixed size portion of the display, said fixed size portion representing a predetermined area on the map.

12. The system of claim 11 , wherein said fixed size portion is a tile and is color coded to indicate an estimated strength of an RF link.

13. A non-transitory computer-readable storage medium having stored thereon computer-readable instructions, the computer-readable instructions comprising instructions that upon execution on one or more computing devices, at least cause the one or more computing devices to:
display, on a user interface operable to allow a controller to remotely interact with an air vehicle, a map including a projected flight path of the air vehicle;
display, on the map, location-based information pertaining to radio frequency (RF) status between the air vehicle and at least one ground radio; and
update the location-based information pertaining to RF status based on a change in a current position of the air vehicle.

14. The computer-readable storage medium of claim 13 , wherein the location-based information are indicative of one or more of antenna pattern, gain, type, and power capabilities.

15. The computer-readable storage medium of claim 13 , wherein the RF status is determined by comparing predicted signal strength of RF links of an area on the map to signal strength corresponding to lost communication and determining if the area on the map will likely experience lost communication.

16. The computer-readable storage medium of claim 13 , wherein the location-based information comprises RF link error rate.

17. The computer-readable storage medium of claim 13 , wherein displaying a map comprises displaying a fixed size portion of the display, said fixed size portion representing a predetermined area on the map, and wherein said fixed size portion is a tile and is color coded to indicate an estimated strength of an RF link.

18. The method of claim 1 , wherein in response to a user request, location-based information outside of a planned flight path for the air vehicle is displayed.

19. The system of claim 7 , wherein in response to a user request, location-based information outside of a planned flight path for the air vehicle is displayed.

20. The computer-readable storage medium of claim 13 , wherein in response to a user request, location-based information outside of a planned flight path for the air vehicle is displayed.
