What is the primary function of hydraulic systems in aircraft?

• A. To provide electrical power
• B. To operate control surfaces and landing gear
• C. To maintain fuel pressure
• D. To manage environmental controls

Answer: (B)

The primary function of hydraulic systems in aircraft is to operate control surfaces and landing gear. Hydraulic systems utilize pressurized fluid to create motion, allowing for the movement of various aircraft components that require significant force. For example, when pilots input commands to change the position of ailerons, elevators, or rudders, hydraulic systems effectively translate those commands into the necessary mechanical movements. Additionally, hydraulic systems are also responsible for operating mechanisms like landing gear retraction and extension, as well as brakes, flaps, and other critical systems where precise and reliable actuation is essential for safe flight operations. The efficient transfer of force through hydraulic fluids makes these systems an integral part of modern aircraft design, ensuring responsiveness and dependability in critical flight functions.
