Abstract

A system and method are provided for displaying a strategic navigational overview of a vehicle, including a navigational map and a marker icon thereon representing an entity pertinent to navigation of the vehicle. A vertical line contacting the marker icon has, contiguous thereto, a current altitude icon representing the current altitude of the vehicle, and a trending icon indicating a direction of a change in altitude of the vehicle.

First claim

What is claimed is:

1. A method for operating a vehicle display system having a display and a processor, the method comprising:
displaying, by the display, a navigational map;
prompting the display, by the processor, to display a marker icon representing an entity pertinent to navigation of the vehicle on the navigational map;
prompting the display, by the processor, to display a vertical line contacting the marker icon;
determining, by the processor, a current altitude of the vehicle and a change in the current altitude of the vehicle;
prompting the display, by the processor, to display a current altitude icon that continuously contacts the vertical line while moving along the vertical line to represent the determined current altitude of the vehicle;
prompting the display, by the processor, to display a trending icon contiguous to the vertical line indicating a direction of the determined change in the current altitude of the vehicle.

2. The method of claim 1 , wherein the vertical line includes a first end contiguous to a terrain and a second end having the trending icon positioned thereon.

3. The method of claim 1 , wherein the marker icon represents weather pertinent to a route of flight of the vehicle.

4. The method of claim 1 , wherein the entity comprises the terrain pertinent to a route of flight of the vehicle.

5. The method of claim 1 , wherein the marker icon represents a special use airspace pertinent to a route of flight of the vehicle.

6. The method of claim 1 , wherein the marker icon represents a waypoint pertinent to a route of flight of the vehicle.

7. The method of claim 1 , further comprising:
determining, by the processor, if the marker is within a threshold associated with a desired route of flight; and
prompting the display, by the processor, to modify the format of the marker icon displayed by the display if the vehicle is within the threshold.

8. The method of claim 1 , further comprising:
prompting the display, by the processor, to display a swath encompassing the desired route of flight.

9. The method of claim 8 further comprising:
determining, by the processor, the dimensions of the swath based on one of a required navigation performance or an estimate of position uncertainty.

10. The method of claim 1 wherein the marker icon represents weather pertinent to a route of flight of the vehicle; and
further comprising prompting the display, by the processor, to:
display an altitude or a range of altitudes associated with the weather.

11. A system for displaying a strategic navigational overview for a vehicle, comprising:
a display configured to:
display a perspective navigational map;

a processor coupled to the display and configured to prompt the display to:
display a marker icon representing an entity pertinent to navigation of the vehicle;
display a vertical line contacting the marker icon;
display a current altitude icon that continuously contacts the vertical line while moving along the vertical line to represent a current altitude of the vehicle; and
display a trending icon contiguous to the vertical line indicating a direction of a change in altitude when the change exists.

12. The system of claim 11 , wherein the display is configured to display the vertical line having a first end contiguous to a terrain and a second end having the trending icon positioned thereon.

13. The system of claim 11 , wherein the marker represents one of the items pertinent to a route of flight selected from the group consisting of weather, terrain, a special use airspace, and a waypoint.

14. The system of claim 11 wherein the processor is further configured to:
determine if the vehicle is within a threshold associated with the desired route of flight; and
modify the format of the marker if the vehicle is not within the threshold.

15. The system of claim 11 , wherein the processor is further configured to prompt the display to:
display a swath encompassing the desired route of flight, wherein the dimensions of the swath are determined based on one of a required navigation performance or an estimate of position uncertainty.

16. A system for displaying a strategic navigational overview for an aircraft, comprising:
a display configured to:
display a moving navigational map;

a processor coupled to the display and configured to prompt the display to:
display a marker icon representing an entity pertinent to navigation of the aircraft;
display a vertical line contacting the marker icon; and
display a current altitude icon that continuously contacts the vertical line while moving along the vertical line to represent a current altitude of the aircraft.

17. The system of claim 16 wherein the processor is further configured to:
display a trending icon contiguous to the vertical line indicating a direction of a change in altitude when the change exists.

18. The system of claim 17 , wherein the display is configured to display the vertical line having a first end contiguous to a terrain and a second end having the trending icon positioned thereon.

19. The system of claim 16 , wherein the marker represents one of the items pertinent to a route of flight selected from the group consisting of weather, terrain, a special use airspace, and a waypoint.

20. The system of claim 16 wherein the processor is further configured to:
determine if the vehicle is within a threshold associated with the desired route of flight; and
modify the format of the marker if the vehicle is not within the threshold.
