Secondary flight controls include which components?

• A. Flaps, Slats, Spoilers, and Trim.
• B. Ailerons, Elevator, and Rudder.
• C. Nacelle anti-ice components.
• D. Wingtip fuel tanks.

Answer: (A)

Secondary flight controls are surfaces that adjust lift, drag, and stability to manage the airplane’s behavior beyond basic attitude control. They let the aircraft fly efficiently at different speeds and configurations with less effort from the pilot. Flaps and slats increase wing camber to boost lift at lower speeds, which is crucial for takeoff and landing. Spoilers disrupt the wing’s airflow to reduce lift and add drag, and they can also help with roll control or act as speed brakes. Trim surfaces hold the aircraft in a desired attitude with reduced control effort from the pilot. In contrast, nacelle anti-ice components and wingtip fuel tanks are systems and storage, not control surfaces, and the primary flight controls—aileron, elevator, and rudder—are the ones used for direct attitude control.
