Abstract

A method of executing a task associated with a flight plan displayed on a navigation display in the form of a graphical image comprises selecting the task, generating symbology on the display graphically representative of the task to be executed and characterized by at least one parameter, and adjusting at least a portion of the symbology by dragging on the display to achieve a desired value of the at least one parameter.

Claims

1. A method of executing a task associated with a flight plan displayed on a navigation display in the form of an interactive graphical image, the method comprising:

selecting the task;

generating symbology on the display graphically representative of the task to be executed and characterized by at least one adjustable parameter; and

adjusting at least a portion of the symbology by dragging on the display to alter the at least one parameter.

2. A method according to claim 1 further comprising altering the flight plan to reflect the desired value of the at least one parameter.

3. A method according to claim 1 wherein the navigation display is a touchscreen and the step of dragging comprises dragging with a finger.

4. A method according to claim 1 wherein the step of dragging comprises dragging with a cursor.

5. A method according to claim 1 wherein the step of adjusting comprises changing the bearing of a segment of the flight plan.

6. A method according to claim 1 wherein the step of adjusting comprises providing a flight plan offset.

7. A method according to claim 1 wherein the step of adjusting comprises changing at least one of a leg distance parameter, a leg time parameter, a turn direction parameter, and a speed parameter, in a hold pattern.

8. A method according to claim 5 further comprising extending the length of the segment on the display to increase adjustment accuracy.

9. A method according to claim 8 further comprising displaying an extended length of the segment in a manner that distinguishes it from the segment itself.

10. A method according to claim 9 wherein the extended portion is a broken line.

11. A method according to claim 9 wherein the segment and the extended portion are displayed as different colors.

12. An avionics display system for deployment onboard an aircraft that receives navigation data indicative of at least position data, the system comprising:

a cockpit display system for receiving and displaying position data and for displaying a flight plan; and

a processor operatively coupled to the cockpit display system and configured to generate a flight plan display including symbology indicative of (1) a current flight plan, (2) a task to be executed, and (3) changes to the flight plan as a result of altering a parameter associated with the flight plan by dragging a portion of the symbology associated with the task.

13. An avionics display system according to claim 12 further comprising touchscreen input device.

14. An avionics display system according to claim 12 further comprising a cursor control input device.

15. An avionics display system according to claim 12 wherein the processor is further configured to alter the symbology to reflect a change in the bearing of the flight plan.

16. An avionics display system according to claim 15 wherein the processor is further configured to generate symbology for extending the segment.

17. An avionics display system according to claim 12 wherein the processor is further configured to (1) generate symbology corresponding to a hold pattern, (2) recognizes changes to a parameter of the hold pattern, and (3) generate symbology reflective of the changes to the hold pattern.

18. An avionics display system according to claim 12 wherein the processor is further configured to (1) recognize a request for a flight plan offset and (2) generate symbology reflective of the offset.

19. A method of altering a flight plan displayed on an avionic display system in the form of a graphical image, the method comprising:

selecting a category of alteration;

generating symbology on the display representative of the category and characterized by at least one parameter; and

dragging symbology on the display to alter the at least one parameter and correspondingly alter the flight plan.

20. An avionics display system according to claim 19 wherein the step of dragging comprises dragging on a touchscreen.
