The Rockwell Collins AHS-4000 Attitude and Reference Heading System (AHRS) is now certified on the Bombardier CRJ1000 NextGen aircraft.
The AHS-4000 AHRS features a solid-state, gyro-based design that is not subject to magnetic abnormalities associated with flux valves and eliminates the need to perform compass swings. The latest generation embedded sensors ensure low power consumption and high reliability, resulting in a 50% improvement in Mean Time Between Failure (MTBF) compared to previous generation systems.
The Rockwell Collins AHS-4000 AHRS is also certified and available as an aftermarket upgrade for CRJ700 and CRJ900 aircraft.
