AUTOMATIC MODE
Applicable to: ,
In the autothrust mode (A/THR function active), the thrust is computed by the FMGC and is limited to
the value corresponding to the thrust lever position (except if the alpha-floor mode is activated).
INDICATIONS ON FMA
The FADECs monitor the positions of the thrust levers, and trigger appropriate indications on the
FMA :
LVR ASYM : Appears in amber (third line on the FMA) if, with A/THR active and both engines
running, one thrust lever is set out of CLB detent.
LVR CLB : Flashes white (3rd line on the FMA), if the thrust levers are not in the CL position,
while the aircraft is above the altitude of thrust reduction with both engines
running.
LVR MCT : Flashes white (3rd line on the FMA), if the thrust levers are not in the MCT
position, after an engine failure (with speed above green dot).

GENERAL
Applicable to:
The fuel system supplies fuel to the combustion chamber at the required flow rate, pressure, and
temperature.
The fuel flows from the tank, via the fuel pump unit and the fuel/oil heat exhanger, to the
Hydromechanical Unit (HMU) and to the fuel nozzles.

Applicable to: ,
The fuel system supplies fuel to the combustion chamber at the required flow rate, pressure, and
temperature.
The fuel flows from the tank, via the Main Engine Pump and the fuel/oil heat exhanger, to the Fuel
Metering Unit (FMU) and to the fuel nozzles.
Control of fuel supply is made by the FADEC via the FMU. High pressure fuel is also used to provide
pressure for some engine component actuators.

FUEL PUMP UNIT
Applicable to:
The HP compressor shaft drives the HP fuel pump assembly. Fuel flows through the LP pump, then
through the fuel/oil heat exchanger and the HP pump (gear pump).
The fuel then divides into a filtered flow for the servo fuel heater and the servo valves of the
hydromechanical unit (HMU), and an unfiltered flow for the metering valve of the HMU.
MAIN ENGINE PUMP
Applicable to: ,
The HP compressor shaft drives the HP fuel pump assembly. Fuel flows through the LP pump, then
through the fuel/oil heat exchanger, a filter, and the HP pump. Fuel then divides into two flows, one
for the servovalve actuators, and one for the FMU’s metering valve.

SHUT-OFF VALVES
Applicable to:
Setting the ENG MASTER switch to OFF directly commands the closing of the LP and HP fuel
shutoff valves for that engine’s fuel system.
It also closes the fuel return valve and opens the bypass valve.
SHUT-OFF VALVES
Applicable to: ,
Setting the ENG1 (ENG2) MASTER switch to OFF directly commands the closing of the LP and HP
fuel shutoff valves for that engine’s fuel system.
Upon closure of the HP fuel shutoff valve, the dump valve opens, which enables any remaining fuel
