DESCRIPTION
Applicable to:
The fuel system :
‐ Stores fuel.
‐ Controls and monitors the correct quantity of fuel.
‐ Supplies fuel to the engines and the Auxiliary Power Unit (APU).
‐ Controls the transfer of fuel to maintain the Center of Gravity (CG) within limits.
‐ Circulates fuel to cool the Integrated Drive Generator (IDG).
‐ Maintains fuel in the outer tanks for wing bending relief.
‐ Allows fuel jettison for rapid weight reduction.
‐ Controls refueling and defueling.

GENERAL
Applicable to:
Fuel is stored in the :
‐ Wings
‐ Trimmable Horizontal Stabilizer (THS).
DESCRIPTION
Applicable to:
The wings have inner and outer tanks. Each inner tank contains two collector cells that :
‐ Maintain a fuel reservoir for the fuel booster pumps and provide negative 'g' protection to feed the
engines.
‐ Are maintained full and contain about 1 000 kg (2 200 lb) of fuel.
Each inner tank is divided into two parts via a SPLIT valve that normally remains open. The inner
tank is used as a single tank and, if tank damage is suspected (i.e. FQI data is lost or there is a rapid
FQI decrease following an engine failure), the SPLIT valve can be manually closed by using the
dedicated pushbutton on the overhead panel.
In each wing, and on the right of the THS trim tank, there is a vent surge tank outboard of the outer
tank.
After refueling to maximum tank capacity, fuel can expand by 2 % (20 °C temperature increase)
without spillage.
There is an overpressure protector in each wing surge tank, in the trim surge tank, and between the
center and each inner tank.
