The FAA has approved a supplemental type certificate for installation of Garmin’s GHA 15 height advisor in a variety of Class I and II aircraft. The height advisor was previously available only for experimental aircraft.

Priced at $2,695, the GHA 15 is not lidar-based like similar devices that give pilots advisory messages about height above ground but uses radio waves. By processing hundreds of measurements per second, the GHA 15 uses digital filters to maintain continuous readings, according to Garmin, “even over water or in challenging terrain environments.”
