3. System Description
__________________
A. Tanks (Ref. 28-11-00)
The aircraft has three fuel tanks and two vent surge tanks. The vent surge tanks are temporary tanks for fuel that can get into the tank venting system. The tanks are as follows:
-
a LH and RH surge tank in the wings
-
a LH and RH wing tank in the wings
-
a center tank in the center wing.
B. Tank Venting System (Ref. 28-12-00)
The tank venting system makes sure the air pressure in the fuel tanks (and the surge tanks) keeps near to the ambient air pressure. This prevents a large difference between these pressures, which can cause damage to the fuel tank/aircraft structure. If a fuel tank overflows during a refuel or a fuel transfer, the tank venting system can contain this fuel. If the fuel flow is more than it can contain, the tank venting system lets this fuel go overboard.
C. Center Tank External Venting System (Ref. 28-13-00)
The fuel or the fuel gas that comes out of the center tank is externally vented to make sure that it does not go into the aircraft structure.

D. Intercell Transfer System (Ref. 28-15-00)
The intercell transfer system controls the movement of fuel from the wing tank outer cell to the wing tank inner cell. The intercell transfer system has two valves in each of the wing tanks that open and close to control the movement of the fuel. The valve position is automatically controlled by the Fuel Level Sensing Control Unit (FLSCU) (Ref. 28-46-00).

E. Fuel Recirculation For Cooling (Recirculation System) (Ref. 28-16-00)
Some of the fuel supplied to the engine is used to cool the oil of the Integrated Drive Generator (IDG). The recirculation system connects the hot fuel output from the IDGs to the wing tanks.
