2 BRAKESH ydraulic systemOverviewThe airplane has three hydraulic systems: A, B and standby. The standby system is used if system A and/or B pressure is lost. The hydraulic systems power the following systems: FLIGHT controls leading edge flaps and slats trailing edge flaps LANDING gear wheel brakes nose wheel steering thrust reversers autopilotsEither A or B hydraulic system can power all FLIGHT controls with no decrease in airplane hydraulic system has a fluid reservoir located in the main wheel well area. System A and B reservoirs are pressurized by bleed air. The standby system reservoir is connected to the system B reservoir for pressurization and servicing.
