The Blue main hydraulic system has the subsequent sub-systems:
- a HP system which supplies the consumers,
- a LP or return system through which fluid returns to the reservoir,
- a suction system.
A. HP System The electric pump 2075GJ usually pressurizes the HP system. The electric pump starts automatically when any one of the engines starts. It then operates continuously until the two engines are stopped. The pushbutton P/B switch 2704GJ in the flight compartment makes it possible for the crew to stop the electric pump. It is also possible to pressurize the system with the electric pump when the engines are stopped. The P/B switch 2703GJ on the maintenance panel 50VU in the flight compartment stops the automatic function and starts the electric pump.
The Ram Air Turbine (RAT) can also supply the Blue hydraulic system with HP fluid. The RAT extends automatically in flight when there is a total AC failure. It is also possible to extend the RAT from the flight compartment with the P/B switches 2805GE or 24XE.

Nov 01/04 CES On the ground, it is possible to pressurize the system from a ground supply. through the self sealing connectors on the ground service panel.
The supply to all of the consumers goes through the HP manifold 2011GM. The HP manifold has pressure switches, a filter, check valves, a transmitter, a solenoid valve and other components which control the system. The supply to all of the consumers other than the slat motor and CSM/G also goes through the leakage-measurement system manifold 2146GM.
B. LP System The LP System returns the fluid from the consumers to the system reservoir 2000GQ. The case drain of the electric pump and the return from the HP manifold are also connected to the LP system. Part of the LP system is also used in the reservoir filling system.
The LP fluid goes through the LP filter 2002GM immediately before it gets
to the system reservoir 2000GQ.
A filter 2084GM is also installed in the case drain line of the electric
pump which goes to the LP system.
