In a hoist system, hydraulically operated components receive power from which system and how are they controlled?

• A. Utility hydraulic system; electrically
• B. Battery electrical system; manually
• C. Pneumatic system; remotely
• D. Manual pump; mechanically

Answer: (A)

Hydraulically operated hoist components get their energy from the aircraft’s utility hydraulic system, and they are controlled electrically. The utility hydraulic pump pressurizes fluid that powers the hoist actuators, while electrical control signals drive valves (often solenoids) to direct that fluid to move the hoist up, down, or hold position. This arrangement allows remote or cockpit control and integrates with safety interlocks, rather than relying on a battery, pneumatic system, or manual pumping.
