The rudder controls yaw, or movement of the aircraft about its vertical axis. Similar to the smaller, movable elevator attached to the trailing edge of the horizontal stabilizer, the rudder is attached to the rear of the fixed vertical stabilizer. As with other components we discussed, the rudder is connected to the rudder pedals in the cockpit via various mechanical linkages; pressing on the left or right rudder pedal moves the rudder left or right, respectively. Most of the time, the rudder is used to maintain coordinated flight, especially when banking the aircraft. Moving the rudder creates a larger camber on the vertical stabilizer, which in turn creates a greater sideways force. This force causes the nose of the aircraft to move left and right, or yaw, around the vertical axis (Figure 3.7).
