SYSTEM AND METHOD FOR MANAGEMENT OF A GROUND OBSTACLE DISPLAY
First Claim
1. A ground proximity warning system for an aircraft, comprising:
- at least one aircraft sensor system operable to acquire aircraft data;
a ground proximity warning computer coupled to the at least one aircraft sensor system that is operable to process the aircraft data to generate ground proximity warning data corresponding to a sensed ground obstruction; and
an indicating system including at least one visual display device that is configured to display an image of a visual symbol corresponding to the sensed ground obstruction, wherein at least one of the computer and the visual display device is controllable to selectively alter an appearance of the visual symbol.

Abstract
A system and methods for managing a visual display in a ground proximity warning system is disclosed. In one embodiment, a system includes at least one aircraft sensor system operable to acquire aircraft data and a ground proximity warning computer coupled to the aircraft sensor system that is operable to process the aircraft data to generate ground proximity warning data corresponding to a sensed ground obstruction. An indicating system including at least one visual display device that is configured to display an image of a visual symbol corresponding to the sensed ground obstruction is coupled to the computer. At least one of the computer and the visual display device is controllable to selectively alter an appearance of the visual symbol on the display.

20. A method of display management for an aircraft ground proximity warning system, comprising:
-
displaying terrain elevations on a visual display device;
displaying a plurality of visual symbols corresponding to sensed ground obstructions on the visual display device;
selecting a range setting for the visual display device; and
if the range setting is less than a predetermined value, displaying the plurality of visual symbols, and if the range setting is greater than or equal to the predetermined value, displaying at least one of a selected portion of the visual symbols or alternate symbols. - View Dependent Claims (21, 22, 23)
