The GHA 15 height advisor offers above-ground-level (AGL) altitude reference at a cost-effective price. It brings radar-based accuracy, aural callouts and visual height indication to pilots of experimental and light sport aircraft equipped with Garmin G3X Touch™ Experimental displays.
Digital Height Advisories: Like other radar-based systems, the GHA 15 height advisor works by transmitting radio waves downward from your aircraft. When the signal is reflected from the surface, the system determines the precise height by using the time delay it takes to receive the signals back.
An All-In-One Module: The compact GHA 15 module is slightly larger than a deck of cards and weighs less than a pound (0.45 kg). The antenna and radar transceiver are built in to the unit, making for easy installation on the underside of you aircraft.
Digital Display Options: The GHA 15 module is compatible with the G3X Touch flight displays to provide visual height advisory readouts.
Audible Height Callouts: Starting at 300 AGL, pilots who have the GHA 15 audio outputs connected will hear altitude callouts at select intervals down to 1 above the surface. These callouts are user-configurable as to how long the prompts go.
Advance Processing: The GHA 15 height advisor can intelligently process hundreds of altitude measurements per second and apply advance digital filters to maintain an accurate continuous reading of your AGL Altitude.
Peace-of-Mind Technology: An affordable solution for experimental and light sport aircraft, the GHA 15 height advisor leverages proprietary Garmin signal processing technology to provide a smooth-tracking AGL altitude reference, even in challenging terrain environments.
