What pressure is the hydraulic system pressurized to?

The hydraulic system in the T-6 is pressurized to 3000 psi, with a tolerance of plus or minus 120 psi. This specification ensures that the hydraulic system operates effectively within a predetermined range, allowing for reliable performance of the aircraft's hydraulic components, such as the landing gear, flaps, and control surfaces. Understanding this pressure range is crucial for maintenance and safety, as both under-pressurization and over-pressurization can lead to malfunctions or failure of the hydraulic system.

The other pressure options provided do not align with the T-6 aircraft specifications and could potentially indicate incorrect operational knowledge or practices regarding the hydraulic systems in this aircraft.
