What is the function of an aircraft hydraulic system?

The function of an aircraft hydraulic system is to provide power for various aircraft mechanical systems. Hydraulic systems are essential in aircraft design as they use fluid pressure to transmit force and perform work. This allows for the operation of critical components such as landing gear, flaps, brakes, and flight control surfaces, making the aircraft more manageable and responsive.

Hydraulic systems are favored in aviation due to their ability to handle high power loads with relatively small and lightweight components. The fluid used in these systems is incompressible, allowing for effective force transmission, which is crucial for the precise operation of various aircraft functions. This ensures better control and safety during operation, particularly during critical phases of flight like takeoff and landing.
