Which computer is the source of trim actuator signals?

Which computer is the source of trim actuator signals?

• A. #2 FCC
• B. #1 FCC
• C. EGIs
• D. Trim Actuators

Answer: (A)

The signals that drive trim actuators come from the Flight Control Computers. In the UH-60S, there are two FCCs, and the trim reference that moves the trim actuators is produced by the second Flight Control Computer. It processes pilot trim inputs and the flight control laws, then sends the appropriate trim command to the actuators to adjust rotor blade pitch and hold the desired attitude. EGIs provide attitude data to systems but do not generate trim commands, and the trim actuators themselves are the recipients of the signal, not the source. So the second FCC is the best answer because it is the unit that generates the actual trim actuator commands.
