The rudder – This is hinged to the trailing edge of the fin. It can move to the right or the left, and is controlled by the rudder pedals:

When the rudder pedal is pushed forward by the right foot, the rudder moves out to the right-hand side, and therefore is reacted on by the airflow. As a result, the tail of the aircraft moves round to the left, the aircraft pivoting on the centre of gravity; the nose thus moves to the right. When the rudder pedal is pushed to the left the reverse happens, the nose moves to left. These movements are in the “yawing plane”. The rudder is normally regarded as a secondary control; it is used to assist the ailerons to perform a correct turn. However, use is made of the rudder in sideslips and in certain unusual conditions of flight.
