Which control surface is primarily responsible for pitch motion?

• A. Rudder
• B. Aileron
• C. Spoilers
• D. Elevator/Stabilator

Answer: (D)

Pitch is the rotation about the aircraft’s lateral axis, which changes the nose’s up-or-down attitude. The elevator on the horizontal stabilizer (or a stabilator, where the entire horizontal tail moves) is the surface that directly creates this pitching moment. By moving up or down, the elevator changes the tail’s aerodynamic force, which tilts the nose accordingly. That makes it the primary control for pitch. The rudder controls yaw (left-right), the ailerons control roll (tilting the wings), and spoilers mainly reduce lift and add drag for descent or rapid speed control, not for steering pitch.
