What is the primary purpose of a hydraulic system in an aircraft?

The primary purpose of a hydraulic system in an aircraft is to operate flight control surfaces and landing gear. Hydraulic systems are vital for transmitting power in various systems throughout the aircraft, enabling the effective movement and control of components like ailerons, elevators, rudders, and flaps, which are essential for flight maneuverability and stability. Additionally, hydraulic systems manage the operation of landing gear during takeoff and landing, as well as the deployment of brakes.

The effectiveness of hydraulic systems in generating the necessary force to operate these components makes them an integral part of modern aircraft design and functionality. They allow for smooth, reliable actions that ensure safety and performance during various flight operations.
