SYSTEM AND METHOD FOR GROUND PROXIMITY WARNING WITH ENHANCED OBSTACLE DEPICTION
First Claim
1. A 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 distance between a sensed ground obstruction and the aircraft; 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 display the visual symbol.

Abstract
Systems and methods for displaying ground obstructions on a visual display are disclosed. In an embodiment, a ground proximity warning 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 to process the aircraft data that generates ground proximity warning data corresponding to a sensed ground obstruction. An indicating system including a visual display device then presents an image of a visual symbol corresponding to the sensed ground obstruction. At least one of the computer and the visual display device is controllable to selectively display the visual symbol.

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, altering display of the number of previously displayed visual symbols, and if the range setting is greater than or equal to the predetermined value. - View Dependent Claims (21, 22)

23. A method of display management for an aircraft ground proximity warning system, comprising:
-
displaying at least one visual symbol corresponding to a sensed ground obstruction on a visual display device, the visual symbol having a first portion and a second portion; and
selecting a display mode for the visual display device, wherein a first display mode is operable to display the first portion and the second portion of the visual symbol, and a second display mode is operable to display the first portion of the visual symbol while suppressing the second portion.
