SYSTEM DESIGN PHILOSOPHY
GENERAL
The fuel system stores fuel in 5 tanks. It supplies
fuel to the engines and APU and recirculates fuel to
cool the oil of the IDGs (Integrated Drive Generators).
A vent surge tank is fitted in each wing.
FEED CONCEPT
Engines are supplied by the center tank fuel via the
center tank pumps.
When the center tank fuel has been used, engines are
supplied by the wing tank pumps, first with the inner
cell fuel and then with the outer cell fuel which flows
to the inner cell.
MANAGEMENT
The different functions of the system are:
- Fuel level and temperature sensing, fuel
transfers, fuel recirculation, refuel/defuel
control and monitoring, indications, warnings
and test.
The fuel quantity indicating system comprises:
- 1 Fuel Quantity Indicating Computer (FQIC).
- 2 Fuel Level Sensor Control Units (FLSCUs).
