The Airbus A320 has 3 different hydraulic systems called GREEN, BLUE and YELLOW system. Each system has its own Reservoir and the normal system pressure is 3000 psi.
Hydraulic Distribution Chart
|GREEN||Is being pressurized by an Engine Driven Pump (EDP) which is connected to Engine N1. Hence the Green EDP can only produce pressure when the engine is running.|
|BLUE||Is being pressurized by an Electric Pump. In an emergency the blue system can also be pressurized by the RAM Air Turbine (RAT).|
|YELLOW||Is being pressurized by an Engine Driven Pump (EDP) which is connected to Engine N2. As a backup power source, an electriv driven pump is also available on the ground and is used for short term usage only. If this pump fails, there is a handpump with which the cargo doors can be opened.|
|PTU||Power Transfer Unit. Is built in to allow system pressure transfer (not fluid transfer) from the yelow to green system and vice versa.|
In this video I am talking about the Hydraulic System of the FSLabs A320-X.
