ARJ-21 Flight Deck

ARJ-700 Flight Deck (COMAC)

The flight deck is fitted with five Rockwell Collins 10in x 8in high-resolution liquid crystal adaptive flight displays. Honeywell is supplying the fly-by-wire flight control system. The avionics suite is based on the Rockwell Collins Pro Line 21 system, including a VHF-4000 voice and data transceiver and an IRU-4000 digital data and audio processor.

The system supports current VDL Mode 2 communications and also has the capability to support controlled pilot data link communications.

A Rockwell Collins FMS 4200 flight management system provides multiple wavepoint vertical navigation, flight time and fuel planning and prediction, standard instrument departures and standard terminal arrival routes and approaches (SIDs and STARS).

A Kaiser Electroprecision throttle control module interfaces with the Collins autopilot, autothrottle and the engine’s FADEC. The avionics suite also includes a fully integrated engine indication and crew alerting system (EICAS).


The navigation systems include Rockwell Collins solid-state weather radar, a Rockwell Collins AHS-3000 attitude heading reference system, a traffic alert and collision avoidance system (TCAS) plus an air data system.

The integrated cockpit panel assemblies and the cockpit lighting control are supplied by Eaton Corporation.

Sagem is providing the flight deck control system which interfaces with the fly-by-wire system, including columns, pedals and a central console.

The aircraft carried out its first commercial flight two years ago with the launch operator Chengdu Airlines and the regional jet is mainly intended for the remote destinations in Northern and Western China.
