Designed for aircraft equipped with digital avionics, the Mark V enhanced ground proximity warning system (EGPWS) exceeds Class A terrain awareness and warning system (TAWS) requirements and provides protection against controlled flight into terrain (CFIT) and windshear.

The Mark V accepts a variety of aircraft parameters as inputs, applying proprietary alerting algorithms to provide the flight crew with aural alert messages, visual annunciations and terrain display of terrain or obstacles in the flight path.
