Which component provides the alternate hydraulic pressure source to extend the landing gear after a secondary system malfunction?

• A. Electric pump
• B. Engine-driven pump
• C. Hydraulic accumulator
• D. Manual pump

Answer: (A)

In the MH-65E, landing gear extension relies on hydraulic pressure, and there is an alternate hydraulic system specifically to provide pressure when the normal (secondary) system isn’t available. The electric pump serves as this alternate source, powered by the aircraft’s electrical system, so you can still extend the landing gear even if the engine-driven or secondary hydraulic pumps are malfunctioning. The engine-driven pump is the primary source under normal operation, not the alternate. The hydraulic accumulator stores pressurized fluid for brief relief but doesn’t actively provide the extended pressurization on demand. The manual pump isn’t the standard source for this function on the MH-65E.
