TAXIING TO RUNWAY 23L
Hint: If you have assigned the front wheel steering via a separate axis assignment on your available hardware
control, this will allow you to steer the CRJ on ground in a realistic way. In addition, this will allow you to
execute the flight controls check in a realistic way during taxi time. If you have not, you need to do the check
during standstill which is the preferred SOP anyway..
Before taxiing out you will be setting flaps to position 8° and check the functionality of the controls. This is
done by moving all three control axes to their endpoints and check their movements in the EICAS display.
The intention to start moving is acknowledged by turning on the TAXI LIGHT. The CRJ starts rolling with just a
bit of power to overcome the inertia and can easily be controlled. If light on weight it may be necessary to
softly brake to avoid exceeding speed limits. Typically, 7 to 10 kts are used on apron areas and 20 to 30 kts on
a free taxiway. This depends very much on weather, taxiway conditions and other traffic. And any instructions
from ground control.
Before reaching the holding point of the departure runway the “Taxi Checklist” must be completed and only
when everything is normal you signal your readiness by switching the transponder code to ON. Some airports
do request to be ON when rolling on the Apron but latest at lining up on departure runway.
