See digital AGL advisory readings from 500’ to touchdown1 on select flight displays.

Audio callouts provide landing cues in select intervals from 300’ down to 1’ AGL².

Get accurate radar-based height readings over land or water.

Small and lightweight, the unit is 100% self-contained for easy mounting on your aircraft.

Audio outputs work with any standard audio panel.

Fly with precise AGL reference, especially in areas where current baro altimeter settings aren’t available.

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 your aircraft.

DIGITAL DISPLAY OPTIONS

In experimental and light sport aircraft, the GHA 15 module is compatible with G3X Touch flight displays. GHA 15 is also approved to interface with our GI 275 flight instrument in select class I/II certified aircraft.¹

AUDIBLE HEIGHT CALLOUTS

Starting at 300’ AGL, pilots who have the GHA 15 audio outputs connected² will hear altitude callouts at select intervals down to 1’ above the surface. These callouts are user-configurable as to how low the prompts will go.

ADVANCED PROCESSING

The GHA 15 height advisor can intelligently process hundreds of altitude measurements per second and apply advanced digital filters to maintain an accurate continuous reading of your AGL altitude.

PEACE-OF-MIND TECHNOLOGY

An affordable solution, the GHA 15 height advisor leverages proprietary Garmin signal processing technology to provide a smooth-tracking AGL altitude reference, even in challenging terrain environments.
