Chelton Flight Systems’ air data and attitude heading reference system (ADAHRS) has been added as an approved sensor on the FlightLogic EFIS supplemental type certificate (STC) for the Bell 206 and 407. Chelton’s ADAHRS is designed for fixed- and rotary-wing aircraft. The system interprets information from the pitot-static system and an outside air temperature probe to generate altitude, vertical speed, airspeed and air temperature.
