The Military & Aerospace Electronics take:
26 July 2023 - The GHA 15 calculates height AGL by sending radio waves to the ground and determining the time it takes to receive the signals back. GHA 15 processes hundreds of measurements per second and applies advanced digital filters to maintain continuous readings – even over water or in challenging terrain environments. AGL readouts are shown on the G3X Touch display and drawn on the altitude tape or gauge at altitudes as high as 500 feet AGL.
Using the readings provided by GHA 15, G3X Touch flight displays can also provide AGL audio callouts via their audio output to help keep the pilot’s eyes looking outside the cockpit. Beginning at 300 feet, the pilot will hear audible AGL altitude callouts at select intervals down to 1 foot AGL. The pilot can configure the callouts to start and stop at specified altitudes. Knowing precise height AGL can be helpful to pilots during landings and flying in areas where limited barometric altimeter setting information is available – such as backcountry flying.
