Abstract

A method is provided for modifying navigation information on a control display unit which has at least one entry field and a plurality of display lines. The method includes at least receiving a plurality of delete command entries, receiving a display line selection, determining the number of delete command entries, identifying a navigation route segment displayed in the selected display line, wherein the navigation route segment displayed in the selected display line comprises at least a first navigation route segment, deleting the first navigation route segment, deleting navigation route segments which follow the first navigation route segment in sequential order until the number of deleted navigation route segments equals the number of delete command entries received, and displaying the navigation information. A system which executes the method is also provided.

Claims

1. A method of modifying navigation information on a control display unit comprising at least one entry field and a plurality of display lines, the method comprising:

receiving a plurality of delete command entries;

receiving a display line selection;

determining the number of delete command entries;

identifying a navigation route segment displayed in the selected display line, wherein the navigation route segment displayed in the selected display line comprises at least a first navigation route segment;

deleting the first navigation route segment;

deleting navigation route segments which follow the first navigation route segment in sequential order until the number of deleted navigation route segments equals the number of delete command entries received; and

displaying the navigation information.

2. The method of claim 1 wherein the navigation route segment comprises at least one of a flight route segment, taxi route segment, navigation procedure, navigation point, aircraft data, and aircraft functions.

3. The method of claim 2 further comprising appending a navigation route segment that follows a last deleted navigation route segment to a navigation route segment preceding the first navigation route segment.

4. The method of claim 3 further comprising:

identifying navigation data corresponding to deleted navigation route segments; and

deleting the navigation data corresponding to the deleted navigation route segments, wherein at least navigation data corresponding to the first navigation route segment is deleted and navigation data corresponding to the deleted navigation route segments which follow the first navigation route segment is deleted.

5. The method of claim 4 wherein the navigation route comprises at least one of a ground navigation route, a flight navigation route, a taxi-out navigation route, and a taxi-in navigation route.

6. The method of claim 5 wherein the navigation data comprises at least one of a geographic location of points on a taxi route segment, taxi route segment heading, a length of the taxi route segment, a distance to an end of the taxi route segment, a time remaining until an end of the taxi route segment is reached, a speed limit, and an instruction.

7. The method of claim 6 wherein the plurality of delete command entries received from the entry field were input by at least one of manual keypad entry, touch screen entry, verbal entry, datalink entry, and stored and recall entry.

8. The method of claim 7 further comprising automatically inputting delimiters between the plurality of delete command entries.

9. The method of claim 8 wherein the entry field is a scratchpad.

10. A system for modifying navigation information displayed on a control display unit, the system comprising:

a control display unit adapted to display navigation information and receive user inputs comprising at least one entry field and a plurality of display lines, wherein the user can input in the entry field at least a plurality of delete commands and the user can select a display line in which a first navigation route segment is to be deleted;

a processor in communication with the control display unit, wherein the processor is adapted to determine the number of delete command entries, delete the first navigation route segment, and delete navigation route segments which follow the first navigation route segment in sequential order until the number of deleted navigation route segments equals the number of delete command entries; and

the processor is adapted to display the navigation information on the control display unit.

11. The system of claim 10 wherein the navigation route segment comprises at least one of a flight route segment, taxi route segment, navigation procedure, navigation point, aircraft data, and aircraft functions.

12. The system of claim 11 wherein the processor is adapted to append a navigation route segment that follows a last deleted navigation route segment to a navigation route segment preceding the first navigation route segment.

13. The system of claim 12 wherein the processor is adapted to identify navigation data corresponding to deleted navigation route segments and delete the navigation data corresponding to the deleted navigation route segments.

14. The system of claim 13 wherein the wherein the navigation route comprises at least one of a ground navigation route, a flight navigation route, a taxi-out navigation route, and a taxi-in navigation route.

15. The system of claim 14 wherein navigation data comprises at least one of a geographic location of points on a taxi route segment, taxi route segment heading, a length of the taxi route segment, a distance to an end of the taxi route segment, a time remaining until an end of the taxi route segment is reached, a speed limit, and an instruction.

16. The system of claim 15 wherein the processor is adapted to receive the plurality of delete command entries and display line selection by at least one of manual keypad entry, touch screen entry, verbal entry, datalink entry, and stored and recall entry.

17. The system of claim 16 wherein the processor is adapted to automatically insert delimiters between the plurality of delete command entries.

18. The system of claim 17 wherein the entry field is a scratchpad.
