SYSTEMS AND METHODS FOR SELECTIVELY ALTERING A GROUND PROXIMITY MESSAGE
First Claim
1. A method of selectively altering a ground proximity warning message for an aircraft, comprising:
- constructing a suitably configured look-ahead envelope that extends outwardly from the aircraft;
detecting an intersection of the look-ahead envelope with a terrain feature and generating the ground proximity warning message; and
altering the ground proximity warning message if at least one alternate flight path exists that avoids the intersection.

Abstract
Systems and methods for selectively altering a ground proximity warning message. In an embodiment, a ground proximity warning system for a flight vehicle includes a processor that is configured to generate a look-ahead envelope that defines a region extending outwardly from the flight vehicle and to generate a terrain proximity message when the defined region intersects a terrain feature. An interface device is coupled to the processor that is operable to configure the system in a first operating mode wherein the generated terrain proximity message is selectively suppressed, and a second operating mode wherein the terrain proximity message is not suppressed.
