Abstract

A system for transitioning navigation data on a mobile platform (such as a train, ship, aircraft or automobile) is provided. The system includes a source of navigation display data and an image control module. The image control module generates image data from the navigation display data based on a position of the mobile platform. The image data includes at least one first navigation display data at a first opacity and at least one second navigation display data at a second opacity. The second opacity is computed based on the position of the mobile platform. The system also includes a display device disposed within the mobile platform that displays the image data.

Claims

1. A system for transitioning navigation display data on a mobile platform comprising:

a source of navigation display data;

an image control module that generates image data from the navigation display data based on a position of the mobile platform, the image data including at least one first navigation display data at a first opacity and at least one second navigation display data at a second opacity, the second opacity computed based on the position of the mobile platform; and

a display device disposed within the mobile platform that displays the image data.

2. The system of claim 1, wherein the first opacity is about 100 percent such that a fully opaque image is rendered based on the first navigation display data.

3. The system of claim 1, wherein the second opacity ranges from about zero to about 100 percent such that the opacity of the image rendered based on the second navigation display data varies based on the position of the mobile platform.

4. The system of claim 3, further comprising:

a speed sensor coupled to the mobile platform that generates a speed of the mobile platform;

a weight sensor coupled to at least one wheel of the mobile platform that provides a signal indicative of a weight of the mobile platform observed at the at least one wheel;

a source of location data that provides a geographic location of the mobile platform; and

a position control module that computes the position of the mobile platform based on at least one of the speed, weight and location of the mobile platform.

5. The system of claim 4, wherein the image control module generates the second opacity based on the speed and weight-on-wheels state of the mobile platform.

6. The system of claim 5, wherein the second opacity is generated if the weight of the mobile platform indicates that the mobile platform is on a ground surface.

7. The system of claim 6, wherein if the mobile platform is on the ground surface, the second opacity varies mathematically based on the speed of the mobile platform.

8. The system of claim 1, further comprising a graphical user interface (GUI) manager module that populates a graphical user interface (GUI) to display the image data.

9. A method of transitioning navigation data on a display of an aircraft comprising:

computing a location of the aircraft relative to an origin or a destination of the aircraft;

rendering a first image on the display at a first opacity based on the location of the mobile platform;

determining a speed of the aircraft;

determining if the aircraft is on a ground surface;

transitioning to a second image on the display at a second opacity based on at least one of the speed of the aircraft and whether the aircraft is on the ground surface; and

computing the second opacity based at least on a speed of the aircraft on the ground surface.

10. The method of claim 9, wherein determining if the aircraft is on a ground surface further comprises:

determining if the aircraft is on a ground surface based on a signal received from a weight sensor coupled to one or more wheels of the aircraft.

11. The method of claim 9, wherein rendering the first image on the display at the first opacity further comprises:

rendering the first image at about 100 percent opacity.

12. The method of claim 9, wherein computing the second opacity further comprises:

determining a mathematical relationship between the speed of the aircraft and the second opacity; and

incrementing the second opacity between about zero percent to 100 percent based on the speed of the aircraft.

13. The method of claim 11, wherein rendering the first image on the display at the first opacity further comprises:

rendering a runway map associated with an airport that is the origin or the destination of the aircraft.

14. The method of claim 9, wherein transitioning to the second image on the display at the second opacity further comprises:

transitioning to airport detail data associated with an airport that is the origin or the destination of the aircraft; and

transitioning to at least one of approach data or departure data associated with airport that is the origin or destination of the aircraft.

15. The method of claim 14, further comprising:

computing a third opacity based on the second opacity;

transitioning to the approach data at the third opacity if the airport detail data is at the second opacity; and

transitioning to the remaining airport detail at the third opacity if the departure data is at the second opacity.

16. An aircraft comprising:

a fuselage;

one or more wheels coupled to the fuselage to support the fuselage on a ground surface;

a cockpit located within the fuselage;

a display located within the cockpit, the display controlled by a display control system, the display control system including;

a position control module that computes position data for the aircraft, the position data including at least one of a speed of the aircraft, and a weight of the aircraft on the one or more wheels of the aircraft; and

an image control module that generates image data for display on the display based on the position data, the image data including at least one navigation display data for display at an opacity computed based on the position of the aircraft.

17. The aircraft of claim 16, wherein the image data further comprises:

at least one first navigation display data at a first opacity;

at least one second navigation display data at a second opacity; and

wherein, the second opacity is computed based on the speed and the weight-on-wheels state of the aircraft.

18. The aircraft of claim 17, wherein the first opacity is about 100 percent such that a fully opaque image is displayed based on the first navigation display data, and the second opacity ranges from about zero to about 100 percent such that the opacity of the image displayed based on the second navigation data varies based on the speed of the mobile platform.

19. The aircraft of claim 18, wherein the second opacity is generated if the weight on the one of more wheels of the mobile platform indicates that the mobile platform is on the ground surface.

20. The aircraft of claim 19, wherein the first image comprises a runway map associated with an airport that is the origin or destination of the aircraft and the second image comprises airport detail, and an approach procedure or a departure procedure associated with the airport that is the origin or destination of the aircraft.
