Hydraulic System Failure and Aircraft Performance
The Hydraulic system on an aircraft is very important, as it allows the operation of various aircraft components. A failure of the hydraulic system in the aircraft can have catastrophic consequences and it is one of the most feared events of a pilot when operating a plane. But, there are multiple separate hydraulic systems, usually three, typically installed on an aircraft. The hydraulic system is used on both small and large aircraft. For small airplanes, it is used to operate wheel brakes, retractable landing gear, and constant speed propellers. On other larger planes, it is used for flight control surfaces, spoilers, wing flaps, and other systems (PHAK, 2016). A basic hydraulic system consists of a reservoir, pump (either hand, electric, or engine-driven), a filter to keep the fluid clean, a selector valve to control the direction of flow, a relief valve to relieve excess pressure, and an actuator (PHAK, 2016). "T he hydraulic fluid is pumped through the syste...
