Which component is controlled by the hydraulic fluid supplied by System A?

• A. Flaps
• B. Rudder
• C. Landing gear
• D. Elevators

Answer: (C)

To understand why the landing gear is controlled by the hydraulic fluid supplied by System A, it's important to recognize the role of hydraulic systems in aircraft operations. Hydraulic systems are commonly used in aviation to operate various components that require significant force, such as landing gear, flaps, and control surfaces.

Landing gear systems often rely on hydraulic pressure for their extension and retraction. When hydraulic fluid from System A is supplied, it activates the mechanism responsible for lowering or raising the landing gear. This hydraulic operation provides the necessary power to overcome the mechanical resistance involved in these actions.

In contrast, while flaps, rudder, and elevators may also be controlled by hydraulic systems, they are typically linked to different hydraulic systems or may operate under different control mechanisms depending on the aircraft design. This specificity to landing gear highlights its reliance on System A for hydraulic fluid, emphasizing the unique role this particular system plays in landing gear operation.
