The MK-VI version of Honeywell's EGPWS has been optimized for regional aircraft and provides protection against controlled flight into terrain (CFIT). CFIT warnings include excessive rate of descent, terrain closure rate, excessive altitude loss after takeoff or missed approach procedure, insufficient terrain clearance, descent below glideslope, an excessive bank angle. It also provides callouts at 500 feet, 200 feet and minimums during approach. (Note: No windshear information is provided by the Mark VI.) Once in use, customers receive free database updates, as they become available.
