Abstract

A system and method are provided for the efficient entry and display of ground taxi routes on an electronic airport map display. The system may include a touchscreen entry device, a display device, a computer, a map database, a vehicle position sensor and a transmitter/receiver. The system may be configured to check the ground taxi entries to ensure that each successive segment is contiguous with the last or next segment, and any gaps or discontinuities in the displayed taxi instructions may be annunciated. An intelligent display of next possible segments may be incorporated into the system.

Claims

1. A system for entry and display of at least one ground movement route for a vehicle, comprising:

an electronic entry device for entry of a series of ground movement segments, wherein said entry device is operatively connected to an output device;

a computer operatively connected to said electronic entry device and said output device, wherein said computer contains a software program which analyzes each ground movement segment in said series of ground movement segments and ensures that each said ground movement segment joins at least one of the following, a previous segment, a subsequent segment, an initial vehicle position and a vehicle destination;

an electronic database including map data that can be accessed by said computer; and

a position determining device coupled to said computer.

2. A system according to claim 1, wherein said electronic entry device is at least one of a liquid crystal display (LCD), a cathode ray tube (CRT), a plasma display and a rear projection display.

3. A system according to claim 1, wherein said electronic entry device includes a touchscreen.

4. A system according to claim 1, wherein said position determining device includes at least one of a Global Positioning System (GPS), an inertial navigation system (INS), another aircraft system, a terrestrial based navigation system, and a manually input position.

5. A system according to claim 1, wherein said electronic entry device further includes a keyboard.

6. A system according to claim 1, wherein said electronic entry device further includes a cursor and a cursor control device.

7. A system according to claim 1, wherein said electronic entry device further includes speech recognition.

8. A system according to claim 1, wherein said electronic entry device uses a graphical display for entry of said ground movement segments.

9. A system according to claim 1, wherein said electronic entry device uses a menu display for entry of said ground movement segments.

10. A system according to claim 1, wherein said system automatically changes the scale of said output device, to at least fully display a currently selected ground movement segment and intersections with said possible successive ground movement segments.

17. A system according to claim 1, further comprising a simultaneous pan and zoom feature.

18. A system according to claim 1, further comprising a transmitter and receiver for the wireless transmittal and receipt of data.

19. A system according to claim 1, wherein said electronic database includes predefined ground movement routes.

20. A system according to claim 1, wherein said electronic entry device is adapted to facilitate at least one of creation, storage and recall of ground movement segment routes.

21. A system according to claim 1, wherein said output device is at least one of, a cathode ray tube (CRT) type display, a liquid crystal (LCD) type display, a head-up (HUD) type display, a plasma display and a rear projection display.

22. A system according to claim 1, wherein said electronic entry device and said and output device are simulated on a desktop computer.

11. A system according to claim 31, wherein said output device separately displays ground movement segments that join at least one of, said previously entered ground movement segment, a subsequent ground movement segment, said initial vehicle position and said vehicle destination.

12. A system according to claim 11, wherein said map data is used to generate an electronically displayed map.

13. A system according to claim 12, wherein said system automatically pans said electronically displayed map to center on at least one of, a currently selected ground movement segment, said initial vehicle position and said vehicle destination.

14. A system according to claim 13, wherein said system automatically pans said electronically displayed map to include at least one intersection with at least one of said previous ground movement segment, said initial vehicle position and said vehicle destination.

15. A system according to claim 14, wherein said system automatically pans said electronically displayed map to center on said currently selected ground movement segment and at least one of said previous ground movement segment, said initial vehicle position and said vehicle destination.

16. A system according to claim 15, wherein said system automatically pans said electronically displayed map to center on an intersection of at least two of, a last entered ground movement segment, a last selected ground movement segment, and said previous segment.

23. A method of entering and displaying at least one ground movement route for a vehicle, the method comprising:

loading an electronic database of map data into an onboard computer;

entering at least one ground movement route into said onboard computer, wherein said entry of said ground movement route is made by entering a series of ground movement segments;

automatically checking each ground movement segment to ensure that each ground movement segment joins at least one of, a previous segment, a subsequent segment, and an initial vehicle position;

displaying an electronic map showing an area of operation for said vehicle;

acquiring vehicle position data;

displaying a vehicle position on said electronic map using said vehicle position data; and

displaying said ground movement segments on said electronic map.
