Honeywell pioneered the first Terrain Awareness and Warning System (TAWS) over 30 years ago. Today, we offer Enhanced TAWS protection in our "EGPWS" for thousands of aircraft of all types around the world. EGPWS is already credited with 30 documented aircraft saves, including the first helicopter / obstacle save with our MK XXII.

General Information

EGPWS uses aircraft inputs such as position, altitude, airspeed and glideslope, along with an internal terrain / obstacle / runway database, to predict potential conflicts between the aircraft's flight path and terrain or an obstacle.
