Frequently Asked Questions
1. What are the aircraft hydraulic fluid types?
There are three aircraft hydraulic fluid types. Mineral oils provide a common base for aircraft hydraulic oil and are the most common. However, they are known for causing oxidation in high temperatures. Synthetic hydrocarbons are for high-performance aircraft, including military aircraft. Phosphate esters offer better fire resistance compared to other aircraft hydraulic fluids. It’s common to use phosphate ester fluids with high-pressure hydraulic systems.
2. What color is aircraft hydraulic fluid?
Aircraft hydraulic fluid can come in a variety of colors based on its specific purpose. However, most fluid is nearly colorless to amber in color.
3. Is aircraft hydraulic fluid flammable?
Yes, most aircraft hydraulic fluid is flammable and should be treated with care.
