-
Electric Pump, Blue System
-
Electric Pump, Yellow System
-Power Control Unit (PCU), Slats
-
Air Relief Valve, Green System Reservoir
-
Air Relief Valve, Yellow System Reservoir.
The AFT collector tank is in the main hydraulic compartment. It is attached to the right side of the keelbeam, forward of FR46. The components which drain into it are:
-
Power Control Unit (PCU), Flaps
-
Power Transfer Unit (PTU)
-Constant Speed Motor/Generator (CSM/G)
-Air Relief Valve, Blue System Reservoir.
The components of the system are connected with silicon hoses and aluminium pipes. The system is designed so that fluid drains into the collector tanks under the influence of gravity.
