In the ARJ21 Rockwell Collins has found the first regional jet application for its ProLine 21 avionics suite. Chinese airframer ACAC specifically selected the package because it wants the new model to boast flight deck commonality with larger airliners. The U.S. avionics house is now testing the kit in its ARJ21 configurations and expects to complete integration of the first version of this by year end.

The suite includes the following elements: five 10-inch by 8-inch high resolution displays; Ethernet-based integrated processing and local area network; communication, navigation and surveillance radars and sensors to support the transition from voice to data links between air and ground; the FMS-4500 flight management system; solid-state weather radar; AHS-3000 attitude heading reference system; engine indication and crew alerting system; full-function autothrottle controls; and a traffic collision avoidance system.
