The ___ is the only computer that can send signals to the Trim actuators?

• A. #1 FCC
• B. #2 FCC
• C. EGIs
• D. MFDs

Answer: (B)

Trim control signals in the UH-60S come from the flight control system through a dedicated channel that is tied to the secondary flight control computer. The secondary (or second) flight control computer is the one programmed to send commands to the trim actuators, while the primary flight control computer handles the main flight control inputs and does not drive the trim actuators. This separation helps ensure that trim adjustments are processed through a specific path and remain reliable even if other parts of the control system are busy or faulted. Inertial navigation systems (EGIs) and display units (MFDs) don’t send trim signals at all; they provide navigation data and cockpit visualization, respectively. So the only computer capable of sending signals to the trim actuators is the secondary flight control computer.
