What hydraulic oil type is identified for use?

The correct answer is MIL-PRF-83282, as it specifies the particular type of hydraulic fluid employed in certain military aircraft, including the MH-60S. This hydraulic fluid is formulated to operate effectively across a wide temperature range and provide excellent anti-corrosion and anti-wear properties, which are crucial for the reliability and longevity of the hydraulic systems in aircraft.

MIL-PRF-83282 is also designed to meet the rigorous performance standards set by military specifications, ensuring that it can withstand the demanding conditions encountered during flight operations. This specification is important in maintaining the safety and performance of the hydraulic systems used in aircraft like the MH-60S.

In contrast, the other options refer to different types of fluids not suited for the hydraulic system. ISO VG 32, for instance, relates to a specific viscosity grade of lubrication oils but does not encompass the necessary military-grade properties required for aircraft hydraulic systems. ATF Type III is an automatic transmission fluid which does not meet the specifications for aircraft hydraulics. SAE 30 is a standard engine oil that lacks the necessary performance characteristics to function as hydraulic fluid. Therefore, MIL-PRF-83282 is the appropriate hydraulic oil type for the MH-60S, ensuring reliable operation within its
