MAST-11 Equivalent Altitude Simulator of Radio Altimeter

MAST-09 Radio Altimeter Detection Unit

The MAST-09 Radio Altimeter Detection Unit is a compact, aerospace-grade component that monitors, validates, and processes radio altimeter data for aircraft. It filters interference, cross-references data with other flight sensors, and detects faults (e.g., signal loss, calibration drift) to deliver reliable terrain-relative altitude info—critical for safe takeoff, low-altitude flight, approach, and landing, even in low visibility. Built to meet strict aerospace standards (e.g., DO-160, DO-178), it withstands extreme environmental conditions, suiting commercial and military aircraft.
