AirSport Corporation is the only manufacturer of Altitude Alerters that work by listening to everything your transponder and encoder are reporting to ATC, both Mode A (squawk code) and Mode C (altitude). This gives you a double benefit! Our instruments are completely portable and do not require permanent installation into your airplane.
