Fuel System Introduction
Purpose
The purpose of the fuel system is to receive fuel from the aircraft tanks and deliver conditioned and metered fuel into the combustion chamber where it is ignited.
Description
Control of the fuel supply is by the EEC via the Fuel Metering Unit (FMU) which moves the Fuel Metering Valve (FMV), with the assistance of the Pressure Drop Governor and Spill Valve, to give the required fuel flow.
High pressure fuel is also used to provide servo pressure (muscle fuel) for the following actuators:
 ACOC actuator.
 BSBV actuators.
 VSV actuator.
 ACC actuator.
The major components of the fuel system include:
 High and low pressure fuel pumps (dual unit).
 Fuel Cooled Oil Cooler (FCOC).
 Fuel filter.
 Fuel metering unit (FMU).
 Fuel distribution valve.
 Fuel spray nozzle (20 off).
 Fuel diverter and return to tank valve (FDRV).
The fuel system controls are on the centre control pedestal and the indications are in the form of an annunciator light and ECAM messages.

Operation
The aircraft pumps deliver the fuel to the engine LP pump.
The LP pump boosts the initial fuel delivery to a pressure so as to prevent low pressure entry into the HP pump. Nominal pressure 150psi. The fuel flows into the fuel cooled oil coolers for the engine and IDG.
The heat management system’s mode of operation will determine the direction of fuel flow; either within the engine or back to the aircraft fuel tanks.
From the engine FCOC the fuel passes through the LP fuel filter. The filter has a 40 micron filtration capability.
The fuel is received by the HP pump and is boosted to a nominal pressure of 1000 psi. The HP pump has a pressure relief valve set at 1360 psi.
The FMU meters the fuel and the excessive HP fuel is diverted back into the LP supply. The FMU is controlled by signals from the EEC.
The fuel flow meter gives indication to the upper ECAM screen of real time fuel flow in KG/H.
The distribution valve filters the fuel and splits the supply into ten separate outlets.
Each of the ten outlets supply fuel to two fuel spray nozzles. The fuel spray nozzles have small filters within them. These carry out ‘last-chance-filtration’ prior to fuel atomisation.
