Which component converts pilot input to rotor movement in UH-60 primary flight control?

Which component converts pilot input to rotor movement in UH-60 primary flight control?

• A. Hydraulic actuators.
• B. Electronic flight computer sensors.
• C. Tail rotor gears.
• D. Swashplate only.

Answer: (A)

In the UH-60, pilot inputs are turned into rotor movement by the hydraulic flight control system. When you move the cyclic, collective, or pedals, signals are translated into hydraulic pressure that drives servo actuators. These actuators apply precise linear motion to the swashplate assembly. The swashplate then distributes that motion to the rotor blades, changing their pitch and tilting the rotor disk to produce the commanded movement. Without the hydraulic actuators providing the actual push and pull, the swashplate cannot move and the rotor would not respond to pilot inputs. The other components don’t perform this conversion: tail rotor gears handle anti-torque and yaw, electronic flight computer sensors provide data but don’t directly move the rotor, and the swashplate needs actuators to create the movement.
