On the Airbus A320, control involves action on the side‐stick position, but the movement is only of the order of centimeters. The A320 flight controls can be described as being electrically signaled, controlled by full authority digital computers and hydraulically supplied, some of them having hydromechanical backup. In normal mode, all the flight control setpoints are set by the digital computers and transmitted from the cockpit to actuators in analog electrical form. Much less covered than electrical flight controls, the functions of main landing gear braking and auxiliary landing gear steering of the Airbus A320 are also realized by suppressing the mechanical signaling to the benefit of SbW. This chapter presents the architecture of the hydraulic generation/distribution of the A320. It examines aircraft hydraulic pumps in detail, in particular those driven by motors that demand specific rotation speeds.
