The SFCCs are responsible for controlling which surfaces?

• A. Flaps and Slats
• B. Rudder and Spoilers
• C. Landing Gear
• D. Elevators and Ailerons

Answer: (B)

SFCCs handle surfaces that influence yaw and roll, namely the rudder and the spoilers. The rudder provides yaw control and coordination, while the spoilers assist in roll control (spoilerons) and can also function as speed brakes. These surfaces are commanded by the SFCCs as part of the flight control laws to achieve the commanded turning and rolling behavior, with stability and redundancy built into the system. The other surfaces—flaps/slats, landing gear, and elevators/ailerons—are managed by different control pathways or systems, not by these computers.
