The Rudder primarily controls which axis movement?

• A. Pitch
• B. Yaw
• C. Roll
• D. Altitude

Answer: (B)

The main concept here is how the rudder affects aircraft rotation. The rudder primarily controls yaw, which is the rotation about the vertical axis. Deflecting the rudder creates a side force that makes the nose point left or right, changing the aircraft’s heading without changing its bank angle. Pitch is controlled by the elevator and tilts the nose up or down, affecting angle of attack and altitude. Roll is controlled by the ailerons and tilts the wings side to side. Altitude isn’t a rotational axis; it changes with pitch and thrust. In practice, you use the rudder to coordinate turns and maintain balanced flight, but its primary action is producing yaw.
