Closed Center Versus Open Center Hydraulics. If you’ve been working with hydraulics for a while, you probably consider a hydraulic system with a variable displacement pump to be more efficient than its fixed displacement counterpart. As a generalization this is true but like most things in hydraulics, it depends.

Aircraft Hydraulic Systems | AeroToolbox

A hydraulic system allows for forces to be applied, multiplied, and transmitted from one location to another through an incompressible fluid medium. Hydraulics are a critical system on almost all modern aircraft. Light aircraft primarily make use of hydraulics to augment and transmit braking forces from the cockpit to the brake disk or drum.
