An aileron roll is similar to the slow roll, and the two maneuvers are often confused with each other. However, unlike a slow roll, an aileron roll is performed at the maximum roll rate, and is uncontrolled in the pitch axis. It consists of a constant attitude change during the maneuver; from the initial pitch-up to the plane following a slight corkscrew path as the nose drops, followed by the final pitch-up. If the pilot picks a reference point on the horizon, directly ahead of the plane, the nose will actually appear to trace a shape similar to the letter "D" above this reference point.
