Which control is responsible for the yaw motion of an aircraft?

The rudder is the primary control surface responsible for managing the yaw motion of an aircraft. Yaw refers to the rotation of the aircraft around its vertical axis, which allows the aircraft to turn left or right. The rudder is located on the vertical stabilizer at the tail of the aircraft and works by deflecting airflow, which generates a force that causes the aircraft's nose to move in the desired direction.

As the pilot moves the rudder pedals, the rudder pivots to the left or right, effectively controlling the yaw and enabling coordinated turns. This function is crucial for maintaining directional control during flight and is particularly important when flying in crosswinds or during maneuvers that require precise directional control.
