The Trim actuators are controlled by which Flight Control Computer?

The Trim actuators are controlled by which Flight Control Computer?

• A. No. 2 FCC
• B. No. 1 FCC
• C. Pilot assist servos
• D. Tail rotor control

Answer: (A)

The trimming function is handled by the second Flight Control Computer. When you select trim, signals from the cockpit trim controls are processed by the second FCC, which computes the required adjustment and commands the trim actuators to move the cyclic inputs to hold the desired attitude. This arrangement gives the aircraft stable, low-workload trimming and keeps primary control processing separate for reliability. Pilot assist servos are not used for trim, and tail rotor control operates through the tail rotor servo system and pedal inputs, not the trim actuators.
