Abstract
A method of controlling a yawing movement of an aircraft running along the ground, the aircraft comprising at least one first landing gear with a steerable bottom part bearing wheels. The method comprises the steps of (1) on the basis of a yaw rate setpoint {dot over (φ)}, determining a wheel-steering prepositioning angle θ; and (2) using closed-loop control which as its input has the yaw rate setpoint and which generates a command to steer the bottom part in order to steer it through a steering angle θequal to the sum of this prepositioning angle θand of an angle θwhich is determined taking account of an error between the yaw rate setpoint {dot over (φ)}and the measured yaw rate {dot over (φ)}when the steerable bottom part is steered by the steering angle θ.
