The engine-driven hydraulic pumps provide continuous hydraulic pressure of how many psi?

The engine-driven hydraulic pumps on the C-17 are designed to generate continuous hydraulic pressure of 4,000 psi. This specification is crucial as it ensures that the hydraulic systems, which control various aircraft functions such as flight control surfaces, landing gear, and brakes, operate efficiently and reliably. The pressure level of 4,000 psi allows for the necessary force to be applied through the hydraulic systems, enabling effective and responsive aircraft performance. Understanding the importance of this pressure helps pilots appreciate the functionality of the aircraft's hydraulic systems and the engineering decisions that went into the C-17 design.
