What is the MIL-SPEC for hydraulic fluid in Naval Aircraft?

The standard for hydraulic fluid used in Naval aircraft is established by MIL-PRF-83282. This specification provides the requirements for a phosphate ester-based hydraulic fluid that is designed to operate in the demanding environments of aviation applications. MIL-PRF-83282 is particularly crucial because it is formulated to resist thermal degradation, provide excellent lubrication, and maintain stability across a wide range of temperatures, making it suitable for the various systems in naval aviation.

The importance of MIL-PRF-83282 also extends to its compatibility with seals and materials commonly used in aviation hydraulic systems, ensuring that it won't cause damage or degradation over time. This contributes significantly to the overall safety and functionality of the aircraft operations.

Understanding the properties and specifications of MIL-PRF-83282 is essential for maintaining aircraft readiness and performance, as utilizing the correct hydraulic fluid is vital in ensuring the reliability of hydraulic systems critical to flight operations and overall aircraft safety.
