Aircraft often rely on complex technology and machinery to operate smoothly, and one of the most crucial aspects in achieving this is the hydraulic system. Hydraulic systems handle tasks ranging from landing gear deployment to the operation of flight control surfaces for many models. Without proper hydraulic fluid levels, such systems would be unable to provide the power for these critical operations to be possible. In this blog, we will explore the importance of hydraulic fluids, notable types, and how they ensure the reliable operation of aircraft systems.
