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 at least one visual display device is controllable to selectively display the visual symbol,wherein at least one of the computer and the at least one visual display device is further operable to display terrain elevations, and at least one of the computer and the at least one visual display device is controllable to suppress the terrain elevations while displaying 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.
