Claim 7:
8. A method for suggesting that a pilot switch operation of an enhanced ground proximity warning system installed in a rotorcraft from a normal mode to a desensitized mode, the method comprising the steps of:
supplying a data source that includes terrain data and obstacle data; and
in the ground proximity warning system:
receiving flight data that is representative of at least a current position of the rotorcraft and of a flight path of the rotorcraft,
retrieving terrain data and obstacle data from the data source along the flight path of the rotorcraft,
evaluating the retrieved terrain data and the retrieved obstacle data to determine variations in elevations of terrain and obstacles in a predetermined area at a predetermined area ahead of the current position and along the flight path of the rotorcraft, and
based at least in part on the determined variations, selectively generating an prompt that suggests that the pilot switch the ground proximity warning system to the desensitized mode.
