Garmin 400/500 series GPS on Rotorcraft with Aeroplane (fixed-wing) TAWS Function Activated

The FAA Special Airworthiness Information Bulletin SAIB: SW-11-24 addresses the use of Garmin 400/500 series GPS Navigation Systems with the airplane Terrain Awareness and Warning System (TAWS) function activated on rotorcraft. It highlights that these TAWS functions are designed for fixed-wing airplanes and are not approved for rotorcraft, such as helicopters, due to differences in operational altitudes and system algorithms. The bulletin specifically mentions rotorcraft equipped with these Garmin systems and the Bell 206B helicopter model with an approved HTAWS STC.
