Fluid reservoirs are crucial for the proper functioning of hydraulic systems in aircraft because they provide the necessary hydraulic fluid that powers the system. These reservoirs ensure a sufficient supply of fluid is available for the operation of hydraulic components, such as brakes, landing gear, and flight control surfaces. The hydraulic fluid transmits force and helps control various motions within the aircraft, creating a system that can efficiently manage mechanical tasks with precise control and low effort.

While manual overrides, mechanical linkage systems, and pressure gauges can play important roles in certain contexts, they are not the primary components that enable the hydraulic system to operate effectively. Manual overrides provide a backup for the system, mechanical linkages connect components, and pressure gauges measure system pressure but do not directly contribute to the hydraulic fluid's availability or functionality.
