Abstract

The disclosed embodiments relate to methods and systems for avoiding a collision between an aircraft on the ground and an obstacle using a three-dimensional visual indication of the area or plane of winglets on the wingtips of the aircraft. The method includes receiving a video image from a camera positioned in one of the winglets, the video image representing a field of view through which the winglet of the aircraft will pass along a present heading of the aircraft. Next a processor determines a three-dimensional area or plane within the field of view through which the winglet of the aircraft will pass. An overlay is displayed within the field of view to assist the pilot in avoiding collisions with obstacles

Claims

1. A method for avoiding a collision between an aircraft on a ground surface and an obstacle, the aircraft having winglets positioned at the wingtips, the method comprising:

receiving, at the processor onboard an aircraft, a video image from a camera positioned in one of the winglets, the video image representing a field of view through which the wingtip of the aircraft will pass along a present heading of the aircraft;

determining, by the processor, a predicted three-dimensional area within the field of view through which the winglet of the aircraft will pass along the present heading of the aircraft; and

displaying the video image on a display together with an overlay representing the predicted three-dimensional area in the field of view;

wherein the overlay provides information to assist in preventing the winglet of the aircraft from colliding with obstacles in the field of view.

2. The method of claim 1, wherein displaying comprises displaying the video image and the overlay on a display within the aircraft.

3. The method of claim 1, wherein displaying comprises displaying the video image and the overlays on a head-up display.

4. The method of claim 1, further comprising generating the overlay to have a shape representing the height of the winglet and the angle of the winglet from a wing coupled to the winglet.

5. The method of claim 4, wherein the overlay has an upper portion representing the tip of the winglet and a lower portion representing a base of the winglet.

6. The method of claim 1, wherein the overlay is displayed is a line-image within the field of view.

7. The method of claim 1, wherein the overlay is displayed as a translucent color image within the field of view.

8. A method for avoiding a collision between an aircraft on a ground surface and an obstacle, the aircraft having winglets positioned at the wingtips, the method comprising:

receiving, at the processor onboard an aircraft, a first video image from a first camera, the first video image representing a first field of view from a first winglet of the aircraft;

receiving, at the processor onboard an aircraft, a second video image from a second camera, the second video image representing a second field of view from a second winglet of the aircraft;

determining, by the processor, a first three-dimensional area through which the first winglet of the aircraft will travel and a second three-dimensional area through which the second winglet of the aircraft will travel within the field of view along a present heading of the aircraft; and

displaying the first video image on a display together with an overlay representing the first three-dimensional area in the first field of view, and the second video image on the display together with an overlay representing the second three-dimensional area in the second field of view;

wherein the first and second overlays provide information to assist in preventing the aircraft from colliding with obstacles in the first and second field of views.

9. The method of claim 8, wherein displaying comprises displaying the first and second video images and the first and second overlays on a display within the aircraft.

10. The method of claim 8, wherein displaying comprises displaying the first and second video images and the first and second overlays on a head-up display.

11. The method of claim 8, further comprising generating the first and second overlays to have a shape representing the respective height of the first and second winglet and the angle of the first and second winglet from a respective wing coupled to the first and second winglet.

12. The method of claim 8, wherein the first and second overlays have an upper portion representing the tip of the respective first and second winglet and a lower portion representing a respective base of the first and second winglet.

13. The method of claim 8, wherein displaying the first and second overlays are displayed is line-images within the respective first and second field of view.

14. The method of claim 8, wherein displaying the first and second overlays comprises displaying a translucent color images within the respective first and second field of views.

15. An aircraft, comprising:

a first wing having a first winglet positioned at a first wing tip, the first winglet have a camera positioned therein for providing a first video image of a first winglet field of view;

a second wing having a second winglet positioned at a second wing tip, the second winglet have a second camera positioned therein for providing a second video image of a second winglet field of view;

processor for determining a respective first and second three-dimensional area for the first and second wingtip to travel within the wingtip field of view along a present heading of the aircraft and for generating a first and second overlay representing the first and second three-dimensional area; and

a display for displaying the first and second video image and the first and second overlay to provide information to assist in avoiding obstacles.

16. The aircraft according to claim 15, wherein the display comprises a cockpit mounted display within the aircraft

17. The aircraft according to claim 15, wherein the display comprises a heads-up display within the aircraft.

18. The method of claim 15, wherein the first and second overlays have an upper portion representing the tip of the respective first and second winglet and a lower portion representing a respective base of the first and second winglet.

19. The method of claim 15, wherein displaying the first and second overlays are displayed is line-images within the respective first and second field of view.

20. The method of claim 15, wherein displaying the first and second overlays comprises displaying a translucent color images within the respective first and second field of views.
