"The lateral axis, or pitch, runs across the tips of each wing. This axis is controlled by the elevator on the planes tail and controls the nose up and down positions of the aircraft. The longitudinal axis, or roll, runs from the nose of the aircraft to the tail and is controlled by the ailerons on each wing. Movement of the ailerons causes the craft to roll over in the air. The final axis is the vertical, or yaw, axis. This is controlled by the rudder on the tail and is used to keep the nose and tail of the plan pointing in the same direction."
