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 and then 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, a taxi route segment, a navigation procedure, a navigation point, aircraft data, or aircraft functions.

3. The method of claim 1 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 1 further comprising:

identifying navigation data corresponding to deleted navigation route segments; and

deleting the navigation data corresponding to the deleted navigation route segments, wherein the navigation data corresponding to the first navigation route segment is deleted and the navigation data corresponding to the deleted navigation route segments following the first navigation route segment is also deleted.

5. The method of claim 1 wherein the navigation route comprises at least one of a ground navigation route, a flight navigation route, a taxi-out navigation route, or a taxi-in navigation route.

6. The method of claim 4 wherein the navigation data comprises at least one of a geographic location of points on a taxi route segment, a 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, or an instruction.

7. The method of claim 1 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, or 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.

19. The method of claim 1 wherein the receiving the plurality of delete command entries and then receiving the display line selection further comprises receiving and displaying the plurality of delete command entries, and then receiving a display line selection.

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

a control display unit configured to receive a plurality of delete command entries, and to then receive a display line selection in which a first navigation route segment is to be deleted;

a processor in communication with the control display unit, wherein the processor is configured to determine the number of delete command entries, delete the first navigation route segment, delete navigation route segments following the first navigation route segment in sequential order until the number of deleted navigation route segments equals the number of delete command entries, and 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, a taxi route segment, a navigation procedure, a navigation point, aircraft data, or aircraft functions.

12. The system of claim 10 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 10 wherein the processor is adapted to identify navigation data corresponding to deleted navigation route segments and to delete the navigation data corresponding to the deleted navigation route segments.

14. The system of claim 10 wherein the navigation route comprises at least one of a ground navigation route, a flight navigation route, a taxi-out navigation route, or a taxi-in navigation route.

15. The system of claim 13 wherein the navigation data comprises at least one of a geographic location of points on a taxi route segment, a 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, or an instruction.

16. The system of claim 10 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, or 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.

20. The system of claim 10 wherein the control display unit is further configured to receive and display the plurality of delete command entries, and to then receive the display line selection.
