What is the maximum allowable psi difference for the hydraulic systems?

The maximum allowable psi difference for the hydraulic systems in the T-6A is indeed set at ±120 psi. This specification is crucial for maintaining proper system performance and ensuring safety during flight operations. The hydraulic systems are designed to operate effectively within this pressure differential to guarantee that both systems can function without compromising the overall aircraft control and performance.

When the psi difference exceeds this limit, it could indicate an underlying issue, such as a malfunction or leak in one of the hydraulic systems, which could potentially lead to failure during critical flight operations. Keeping the psi difference within the ±120 psi range ensures that the hydraulic systems remain balanced and responsive, which is essential for maneuvers, landing gear operation, and flight control surfaces. Understanding these parameters is vital for pilots to ensure they can maintain aircraft integrity and safety.
