Hydraulic power for the landing gear in an aircraft is typically provided by an electrically-driven hydraulic power pack. This system enables the efficient and reliable operation of the landing gear mechanism, as hydraulic systems are favored in aviation for their ability to exert high forces with minimal weight.

The electrically-driven hydraulic power pack generates hydraulic pressure by converting electrical energy into hydraulic energy. This allows for rapid deployment and retraction of the landing gear, which is crucial during takeoff and landing. This method is particularly prevalent in modern aircraft, as it contributes to automation and can be integrated with various electronic systems, promoting overall efficiency.

The other options do not represent the standard means of providing hydraulic power for landing gear. Pneumatic actuators would primarily use air pressure, rather than hydraulic pressure, while mechanical linkages would depend on physical connections and would generally lack the efficiency and responsiveness of a hydraulic system. Manual hydraulic pumps involve a direct physical operation by the pilot, which is less common in advanced aircraft where automation and efficiency in operation are priorities.
