The air data attitude heading reference system is a revolutionary, dual-channel system that combines attitude, altitude, airspeed, air temperature and heading information into a single box.
The air data attitude heading reference system (ADAHRS) is a revolutionary, dual-channel system that combines attitude, altitude, airspeed, air temperature and heading information into a single box. Honeywell developed the dual-channel ADAHRS function with state of the art micro-electromechanical sensors (MEMS). This design provides the lowest size and weight solution with the highest reliability available in the business and general aviation and civil helicopter markets.
Additional features include:
Honeywell designed and produced pressure and aviation-grade MEMS sensors for maximum accuracy and reliability – no global positioning system augmentation required
Automated integrity monitor detects and eliminates incorrect attitude information, leading to improved safety and reduced pilot workload
System can re-initialize in flight
Reduced vertical separation minimum (RVSM)-compliant air data computer
Remote-mounted for improved performance and ease of installation
Automated aircraft alignment
ARINC 429 digital output
Airspeed gain scheduling of the flight control system
Redundant sensor set for altimetry and airspeed
Static source error correction (SSEC) for either altitude or airspeed
