Aircraft Hydraulic Fluids
Hi
Before i get shot off the moderators i apologise for posting 2 threads next to each other.
My question is about aircraft hydraulic fluids. What types of hydraulic fluids ar ein use today? I have 3 main types in my notes those being Castor Based, Mineral Based and Synthetic Ester Based fluid. Do aircraft still use petroleum based fluid? I thought they were taken out years ago due to their high flamability but am not too sure. Also, another quick question, does anyone knwo what type of hydraulic fluid is used in light aircraft and what different properties light aircraft hydraulic systems require compared to the properties required by larger commercial aircrat.
Thank you for your time
