The airstairs in the RJ Professional can be deployed under their own weight by first setting the STAIR RETRACTION switch to the extended position, then opening the passenger door and left-clicking on the airstairs’ handrail.

The airstairs are retracted hydraulically and require pressure from the Yellow hydraulic system, or from the airstairs accumulator (if fitted). To retract the airstairs, ensure the airstairs have sufficient hydraulic pressure either via the airstairs accumulator or by turning on the AC Pump on the overhead panel in the cockpit, then set the STAIR RETRACTION switch to retract. Once the stairs are in the vertical position, left click on one of the airstairs’ handrails to stow them in their compartment. 

An AIRSTAIRS ACCUMULATOR can be fitted to the aircraft via an option on the EFB Aircraft page. With this option enabled, the airstairs accumulator stores enough pressure to facilitate two full retractions of the airstairs without requiring the Yellow hydraulic system to be pressurised. Once pressure in the airstairs accumulator has been depleted, they will fall under gravity and will require Yellow system hydraulic pressure to retract and to recharge the accumulator. 

Integral AIRSTAIRS LIGHTS can also be fitted to the aircraft via an option on the EFB Aircraft page. With this option enabled, the airstairs lighting will be lit whenever the STAIR RETRACTION switch is not in the retracted position. The lights are powered from the 28 volt AC ground service busbar.
