What is the central component of the AFCS?
The central component of AFCS is two redundant FCCs. Each Computer receives signals from the pilots' controls, motion sensors, control panels, avionics systems, embedded GPS/inertial navigation, and air data computers to compute commands which are sent to the cockpit, trim actuators, SAS actuators, and stabilator actuators. The No. 2 FCC is the only FCC that sends signals to the trim actuators for dynamic flight control inputs.
