Rockwell Collins AHS-4000 Certified on CRJ1000 NextGen

Rockwell Collins has announced that its AHS-4000 Attitude and Reference Heading System (AHRS) is now certified on the Bombardier CRJ1000 NextGen aircraft. The announcement was made at the 36th Annual Regional Airlines Association (RAA) Convention in Nashville, Tenn. The Rockwell Collins 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 reliability, resulting in a 50 percent improvement in Mean Time Between Failure (MTBF) compared to previous generation systems, according to the company.
