What is the central component of the AFCS systems?

• A. 2 redundant FCCs
• B. 1 FCC
• C. 3 FCCs
• D. 4 FCCs

Answer: (A)

The automatic flight control system centers on two redundant Flight Control Computers. These two FCCs act as the brains of AFCS, taking in pilot inputs and sensor data, applying the flight control laws, and sending commands to the control actuators. Having two in a redundant arrangement ensures that if one FCC fails, the other can continue managing the system, preserving control and allowing a safe continuation of the flight. The rest of the AFCS components—sensors, actuators, and trim functions—rely on these FCCs, so they form the essential backbone of the system.
