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;
identifying at least one alternate flight path, wherein the aircraft possesses suitable performance characteristics to execute the alternate flight path to navigate;
in response to identifying the at least one alternate flight path, continuing a first operating mode that suppresses the ground proximity warning message; and
altering the ground proximity warning message from the suppression state if the at least one alternate flight path comprising an executable aircraft bank angle 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.

10. 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; identifying from a plurality of alternate flight paths at least one alternate flight path, wherein the alternate flight path is identified if the aircraft possesses suitable performance characteristics to execute at least an aircraft bank angle to navigate along the alternate flight path; altering the ground proximity warning message if at least one alternate flight path comprising the executable aircraft bank angle exists that avoids the intersection; in response to failure to identify the at least one alternate flight path, overriding a first operating mode that suppresses the ground proximity warning message; and in response to overriding the first operating mode, issuing the ground proximity warning message, wherein the ground proximity warning message is altered from a suppressed state to an issued state. - View Dependent Claims (11, 12)
