How many engine driven hydraulic pumps are in the Dassault Falcon 7X?

The Dassault Falcon 7X is equipped with a total of three engine-driven hydraulic pumps. These pumps play a critical role in the aircraft's hydraulic system, supplying hydraulic fluid to various systems such as flight control surfaces, landing gear, and brakes. The design includes one hydraulic pump on each of the three engines, ensuring that there is redundancy and reliability in the hydraulic system.

While the other options suggest higher numbers, the Falcon 7X has been specifically engineered with three engine-driven hydraulic pumps to balance efficiency and reliability. This setup provides adequate performance under various operating conditions while minimizing weight and complexity.
