A Rolling Out of a Right Turn The same principle applies when rolling out of a turn.
To begin any rollout, you’ll apply aileron to reduce the

upward decreasing the lift and the drag on that wing). The
nose wants to yaw to the right because of the adverse yaw
produced by the lowered right aileron (Figure 55). To keep
the nose from yawing, you must use left rudder in coordi-

left rudder simultaneously. You’re using just enough left
