____________________________________
 1. General
_______
 A. Nose Wheel Steering
 (Ref. Fig. 001)
 Nose wheel steering is possible from the cockpit as follows:

 (1) During taxi, and more generally at low speed, through action on a handwheel. There are two identical handwheels: one for the Captain, one for the First Officer. In the event of simultaneous operation, the orders that the handwheels give are algebraically added. The maximum travel of the wheels is plus or minus 74 deg. The maximum corresponding travel of the handwheel is plus or minus 75 deg. However, the law between these two travels is not linear.
