Where are the engine-driven hydraulic pumps located?

The engine-driven hydraulic pumps are strategically located in the respective engine accessory gearboxes. This placement is essential because it allows the pumps to be directly driven by the engine, ensuring a reliable and continuous supply of hydraulic power necessary for various aircraft systems, such as flight controls, landing gear operations, and braking systems.

This configuration also minimizes the complexity of the hydraulic system, reducing the number of required components and the overall weight of the aircraft while enhancing efficiency. By integrating the pumps into the engine accessory gearboxes, they can respond immediately to engine power changes, providing hydraulic pressure as needed during different phases of flight.

In contrast, the other locations mentioned, such as the right aft gear pod, wheel wells, and cargo compartment, do not provide the same level of accessibility, efficiency, and reliability for the hydraulic pumps. These locations might hold other equipment or systems but are not suitable for the placement of engine-driven hydraulic pumps due to operational demands and design constraints.
