Fuel System

The A330-200 has one center tank, one tail tank, and on each wing half, an Inner and outer tank.

The inner tank is further divided into the inner tank and a collector tank.

The fuel capacity of the aircraft is approx. 110,000 kg or 90,000 liters of fuel.

The fuel is stored in the wing, tail and center tanks. The fuel system ensures supply of fuel to the engines and the APU.

The fuel system moves fuel from Outer to Inner wing tanks and from Tail to inner tanks for wing bending alleviation and for Cg control.

The fuel is also used to cool the IDG on each engine.

CG Control

The FMGCs mange the CG of the aircraft during flight.

For moving the CG aft, the FMGCs provide an Aft Transfer signal that causes the fuel to be transferred from the inner tanks to the tail tank.

For moving the CG Foward, the FMGCs provide an Fwd Transfer signal that causes the fuel to be transferred to the inner tanks to the tail tank.

These transfers start occurring after the aircraft has climbed through FL255

During descent, the FMGCs command a forward transfer.
