What is the function of the rudder on an aircraft?

• A. Attached to the rear of the vertical stabilizers and used to control motion of the aircraft from left to right.
• B. Controls the aircraft's pitch (up and down).
• C. Provides the main lift force for sustained flight.
• D. Helps stabilize the aircraft during takeoff.

Answer: (A)

The function being tested is yaw control: the rudder is a movable surface on the tail’s vertical stabilizer that deflects air to push the nose left or right. This lets the pilot steer the aircraft horizontally, coordinate turns, and counter effects like crosswinds or engine asymmetry. It isn’t responsible for lifting the aircraft (that’s the wings), nor for controlling pitch (that’s the elevator), and while it can help with keeping the nose aligned in some takeoff situations, its primary role is managing left-right direction.
