Abstract

Methods and systems are provided for presenting information on a display device associated with an aircraft. An exemplary method involves displaying a navigational map on the display device, obtaining status information for the aircraft, determining an amount of procedure information to be displayed based at least in part on the status information, and displaying the determined amount of aircraft procedure information on the display device overlying the navigational map. The procedure information prescribes operation of the aircraft during execution of an aircraft procedure.

Claims

1. A method for presenting information on a display device associated with an aircraft, the method comprising:

displaying, on the display device, a navigational map;

obtaining status information for the aircraft;

determining an amount of procedure information to be displayed based at least in part on the status information, the procedure information prescribing operation of the aircraft during execution of an aircraft procedure; and

displaying, on the display device overlying the navigational map, the determined amount of aircraft procedure information.

2. The method of claim 1, further comprising displaying, on the display device overlying the navigational map, a graphic element of the aircraft procedure, the graphic element having textual information associated therewith, wherein:

determining the amount of procedure information to be displayed comprises determining an amount of the textual information to be displayed based at least in part on the status information.

3. The method of claim 2, further comprising increasing the amount of the textual information displayed on the display device when a distance between a location of the aircraft and a location associated with the graphic element is less than a threshold value.

4. The method of claim 2, further comprising increasing a size of the textual information displayed on the display device when a distance between a location of the aircraft and a location associated with the graphic element is less than a threshold value.

5. The method of claim 2, further comprising decreasing the amount of the textual information displayed on the display device when a distance between a location of the aircraft and a location associated with the graphic element is greater than a threshold value.

6. The method of claim 2, further comprising updating the amount of the textual information displayed on the display device in response to a change in the status information.

7. The method of claim 2, the aircraft procedure having an associated flight phase, wherein the method further comprises:

identifying a current flight phase of the aircraft based on the status information; and

increasing the amount of the textual information displayed on the display device when the current flight phase corresponds to the associated flight phase.

8. The method of claim 7, the aircraft procedure comprising an approach procedure associated with an approach phase, wherein the amount of the textual information displayed on the display device is increased when the current flight phase corresponds to the approach phase.

9. The method of claim 2, wherein the amount of the textual information to be displayed on the display device is determined based on a display setting for the navigational map and the status information.

10. The method of claim 9, further comprising adjusting the amount of the textual information displayed on the display device in response to a change in the display setting.

11. The method of claim 10, the display setting comprising a range setting, wherein adjusting the amount of the textual information displayed comprises:

increasing the amount of the textual information displayed on the display device in response to a decrease in the range setting; and

decreasing the amount of the textual information displayed on the display device in response to an increase in the range setting.

12. The method of claim 9, the display setting comprising a range setting, wherein the method further comprises graphically indicating an association between the textual information and the graphic element in response to an increase in the range setting.

13. The method of claim 12, the graphic element comprising a navigational segment, the textual information being initially displayed along the navigational segment, wherein graphically indicating the association comprises:

displaying the textual information offset from the navigational segment in response to the increase in the range setting; and

displaying a line segment between the navigational segment and the textual information.

14. The method of claim 2, further comprising:

updating the navigational map in response to a change in a heading of the aircraft; and

radially repositioning the textual information with respect to the graphic element in a manner that is influenced by the change in the heading of the aircraft.

15. The method of claim 1, wherein the determined amount of aircraft procedure information is displayed as an inset within the navigational map.

16. The method of claim 15, further comprising displaying a graphical representation of the aircraft within the inset, wherein a location of the graphical representation of the aircraft with respect to the displayed aircraft procedure information accurately reflects a real-world location of the aircraft with respect to the displayed aircraft procedure information.

17. The method of claim 1, the determined amount of aircraft procedure information including a graphic element corresponding to a navigational reference point, the graphic element being displayed overlying the navigational map, wherein the method further comprises displaying a graphical indicia proximate the graphic element when a geographic location of the navigational reference point is outside a geographic area of the navigational map.

18. A method for presenting an aircraft procedure prescribing operation of an aircraft on a display device associated with the aircraft, the method comprising:

displaying, on the display device, a navigational map associated with a current location of the aircraft;

displaying, on the display device, a graphic element of the aircraft procedure overlying the navigational map, the graphic element having textual information associated therewith;

obtaining a display setting for the navigational map;

obtaining status information for the aircraft;

determining a subset of the textual information to be displayed based on the status information and the display setting; and

displaying, on the display device, the subset of the textual information.

19. The method of claim 18, further comprising:

decreasing an amount of textual information displayed in response to a change in the display setting; and

after decreasing the amount of textual information, increasing the amount of textual information in response to a change in the status information.

20. The method of claim 18, further comprising:

increasing an amount of textual information displayed in response to a change in the display setting; and

after increasing the amount of textual information, decreasing the amount of textual information in response to a change in the status information.

21. The method of claim 18, wherein determining the subset of the textual information comprises:

identifying a first category of the textual information for display based on a first priority criterion associated with the first category; and

excluding a second category of the textual information from the subset based on a second priority criterion associated with the second category, the second priority criterion being lower than the first priority criterion.

22. A system comprising:

a display device onboard an aircraft, the display device having a navigational map pertaining to operation of the aircraft displayed thereon;

a data storage element configured to maintain procedure information for an aircraft procedure; and

a processing system coupled to the display device and the data storage element, wherein the processing system is configured to;

obtain status information for the aircraft;

determine an amount of the procedure information to be displayed based at least in part on the status information; and

display, on the display device, the determined amount of aircraft procedure information overlying the navigational map.

23. The system of claim 22, the procedure information including a graphic element having textual information associated therewith, wherein the processing system is configured to:

display, on the display device, the graphic element overlying the navigational map;

determine the amount of the textual information to be displayed based on the status information; and

display, on the display device, the determined amount of textual information overlying the navigational map.
