The aircraft has three main hydraulic systems. They are identified as the Green, Blue and Yellow systems. Together they supply hydraulic power at 3000 psi (206 bar) to the main power users. These include the flight controls, landing gear, cargo doors, brakes and thrust reversers. Services which are not used during flight (cargo doors, brakes, landing gear and nosewheel steering) are isolated from the main supply. (Ref. Fig. 003, 004)
The three systems are not hydraulically connected. Where possible they are kept apart to keep to a minimum the effect of engine or tire burst, or other damage. There are no hydraulic pipes in the passenger cabin or flight compartment. (Ref. Fig. 005)
High pressure (HP) pipes which are not in fire zones are made of titanium alloy and are not painted. HP pipes in fire zones are made of stainless steel. Low pressure (LP) pipes are made of light alloy and are painted for protection against corrosion. In certain special areas (landing gear bays), the LP pipes are made of stainless steel or titanium alloy. Stainless steel and titanium alloy pipes are electrically bonded with bonding leads and clips. It is not necessary to bond light alloy pipes. Flexible pipes are used where it is necessary because there is vibration or movement between components. (Ref. Fig. 006)
Manifolds are used where possible in both the HP and LP systems. The maximum quantity of components are installed on the manifolds to prevent damage to or movement of the pipes when components are replaced. The manifolds have bobbin type connections for some components.
