Which statement correctly matches the primary flight control surfaces with their primary functions?

• A. Ailerons control yaw; Elevators control pitch; Rudder controls roll.
• B. Elevators control pitch; Ailerons control roll; Rudder controls yaw.
• C. Ailerons control roll; Elevators control pitch; Rudder controls yaw.
• D. Ailerons control pitch; Elevators control yaw; Rudder controls roll.

Answer: (B)

The main idea is which control surface moves which axis: roll, pitch, and yaw. Ailerons, located on the wings, move in opposite directions to create different lift on each wing, causing the airplane to roll. Elevators, on the horizontal stabilizer, change the tail’s angle of attack to lift or lower the nose, producing pitch. The rudder on the vertical stabilizer deflects airflow to create a yawing moment, turning the nose left or right. Therefore, elevators control pitch, ailerons control roll, and rudder controls yaw.
