What are the computers that provide backup control for the elevators and ailerons called?

• A. SFCCs
• B. ECAM Monitors
• C. FADECs
• D. SECs

Answer: (D)

The thing that provides backup control for the elevators and ailerons is designed to step in when the primary flight-control computers fail, keeping the aircraft controllable in pitch and roll. These standby electronic computers are wired to the control surfaces so pilot inputs still move the elevators and ailerons, even in degraded or failed-electronics situations. They act as a safety net, delivering enough authority to maintain basic control until normal systems are restored or the situation is stabilized. ECAM monitors are just display units that show system information, and FADECs handle engine control, not control surface backup. SFCCs refer to other flight-control computer configurations, not the standby backup path for elevator and aileron control.
