The Innovative Aerosystems (IA) ADAHRS (Air Data, Attitude and Heading Reference System) is a compact, lightweight digital solution engineered to replace traditional Directional Gyros (DG), Vertical Gyros (VG), legacy AHRS units, and standalone Air Data computers.
Ideal for both retrofit and OEM applications, this next-generation ADAHRS intAll aircraft-specific configurations—including DG Mode, Maximum Allowable Airspeed Limit, static source error correction, attitude and MSU calibrations, and temperature probe type—are stored in the Installation Configuration Module (ICM). This allows for quick replacement and minimal reconfiguration when servicing or upgrading Line Replaceable Units (LRUs).
