Abstract

A system and method are provided for displaying terrain altitudes on an aircraft display that are easily understood by the pilot. A plurality of bands are defined, wherein each band defines a range of altitudes of terrain in the vicinity of the aircraft. A list of altitudes representing each band is displayed in a legend. A band is highlighted when a number associated therewith is selected, and a number is highlighted when the band associated therewith is selected. The band or number may be selected, for example, by cursor, or the band may be selected by position of the aircraft.

Claims

1. A display system for displaying terrain altitudes within an aircraft, the display system comprising:

a system configured to determine a location of the aircraft and altitude data of the terrain in the vicinity of the aircraft;

a processor coupled to the system and configured to;

define a plurality of bands, wherein each band comprises a range of altitudes of the terrain void of a number defining an altitude; and

create a list of numbers of altitudes representative if each band; and

a display coupled to the processor and configured to display the bands and the list, wherein each band is displayed in a different format and each of the numbers in the list are displayed in the format of the band for which it represents.

2. The display system of claim 1 wherein the processor is further configured to:

highlight one of the bands when the number associated with that band is selected.

3. The display system of claim 1 wherein the processor is further configured to:

highlight one of the numbers when the band associated with that number is selected.

4. The display system of claim 1 wherein the processor is further configured to:

select the band or the number by movement of a curser.

5. The display system of claim 1 wherein the processor is further configured to:

select the band when a displayed icon representing the aircraft is positioned over the band.

6. The display system of claim 1 wherein each format comprises a unique color.

7. The display system of claim 1 wherein the processor is further configured to:

display an icon representative of the aircraft within the list at the current altitude.

8. The display system of claim 1 wherein the processor is further configured to:

display an icon representative of the aircraft at the current altitude, and the current altitude within or adjacent the icon.

9. The display system of claim 1 wherein the processor is further configured to:

display the band and the representative number for an altitude in a special format when the aircraft goes below that altitude.

10. A method of displaying terrain altitudes on a display within an aircraft, the method comprising:

defining a plurality of bands, wherein each band comprises a range of altitudes of the terrain in the vicinity of the aircraft and wherein each band is void of a number representative of the altitude;

creating a list of numbers of altitudes representing each band; and

displaying the bands and the list on a moving map, wherein each band is displayed in a unique format or color and each of the numbers in the list are in the format of the band for which it represents.

11. The method of claim 10 further comprising:

highlighting one of the bands and the number from the list representing that band when one of the band or the number are selected.

12. The method of claim 10 further comprising:

highlighting one of the bands when the number associated with that band is selected.

13. The method of claim 10 further comprising:

highlighting one of the numbers when the band associated with that number is selected.

14. The method of claim 11 wherein the highlighting comprises selecting the band or the number by movement of a curser.

15. The method of claim 11 wherein the highlighting comprises selecting the band when a displayed icon representing the aircraft is positioned over the band.

16. The method of claim 11 wherein each format comprises a unique color.

17. The method of claim 10 further comprising displaying an icon representative of the aircraft within the list at the current altitude.

18. The method of claim 10 further comprising displaying an icon representative of the aircraft at the current altitude and the current altitude within or adjacent the icon.

19. A method of displaying terrain altitudes on a display within an aircraft, the method comprising:

defining a plurality of bands, wherein each band comprises a range of altitudes of the terrain in the vicinity of the aircraft and wherein each band is void of a number representative of the altitude;

creating a list of numbers of altitudes representing each band; and

displaying the bands and the list on a moving map, wherein each band is displayed in a unique format or color and each of the numbers in the list are in the format of the band for which it represents;

selecting the band or the number by position a cursor thereover or when an icon representing the location of the aircraft is positioned over the band;

highlighting the band when the number from the list representing that band is selected;

highlighting the number when the band associated therewith is selected; and

displaying an icon representing the aircraft at the current altitude in the list.

20. The method of claim 19 further comprising displaying the current altitude within or adjacent the icon displayed in the list.
