The engine-driven pump pressurizes the hydraulic system to which of the following pressures?

The engine-driven pump in the T-6 aircraft is designed to pressurize the hydraulic system to a nominal pressure of 3000 psi with a specified tolerance of plus or minus 120 psi. This means the operational pressure can vary within the range from 2880 psi to 3120 psi, which ensures that the hydraulic system can function effectively while accommodating variations in performance and environmental conditions.

The choice of 3000 psi as a nominal value is significant because it provides sufficient hydraulic pressure to operate essential flight control surfaces and system components to ensure safety and responsiveness in flight operations. Maintaining this specific pressure is crucial for the system's efficiency and reliability in the dynamic environment of flight.

Understanding this pressure range is essential for any maintenance, troubleshooting, or operational considerations regarding the hydraulic systems in the T-6 aircraft. It highlights the importance of the engine-driven pump's role in managing hydraulic power effectively.
