INTRODUCTION
Applicable to: ALL
Engines usually start using the Automatic Starting function. The Full Authority Digital Engine Control
(FADEC) systems control this engine Automatic Starting function, and takes appropriate action, if
engine parameters are exceeded. This function extends significantly the duration of engine life.
The thrust levers must be confirmed at "idle" before engine-start. If the thrust levers are not at "idle",
the thrust increases above idle after engine-start, and can result in a hazardous situation. However,
an ENG START FAULT ECAM warning triggers, to indicate that the flight crew must set the thrust
levers to "idle".
AUTOMATIC STARTING SEQUENCE
Criteria: A340
Applicable to: , , , , , , , , , , , ,
The APU bleed allows to start two engines simultaneously. However, the ENG MASTER switches
have to be set ON with a certain delay (Delta N2 about 10 %), in order to allow a proper functioning
of the NO Break Power Transfer function of the electrical generators, and therefore, avoid electrical
transients on computers and display units.
Engine 1 and 2 should be started first, in order to pressurize the blue hydraulic system, that supplies
the parking brake accumulator.
When the ENG START selector is set to "START", the FADECs are electrically-supplied. When there
is sufficient BLEED PRESS, the PF begins the start sequence by setting the ENG MASTER switches
to ON, one after the other with a slight delay (N2 about 10 %). The flight crew should monitor the
start sequence:
• Start valve opens
• N2 (or N3 for Rolls-Royce engines) increases
• IGN A(B)
• Fuel flow
• EGT
• N1
• Oil pressure increases
• Start valve closes
• IGN indication off (Refer to FCOM/PRO-NOR-SOP-08 AUTOMATIC ENGINE START ).
When engines 1 and 2 are at idle, or when AVAIL is displayed, the PF can start engines 3 and 4.

The engines are started in sequence, preferably engine 1 first, in order to pressurize the blue
hydraulic system, that supplies the parking brake accumulator.
When the ENG START selector is set to "START", the FADECs are electrically-supplied. When there
is sufficient BLEED PRESS, the PF begins the start sequence by setting the ENG MASTER switch to
ON. The flight crew should monitor the start sequence:
• Start valve opens
• N2 (or N3 for Rolls-Royce engines) increases
• IGN A(B)
• Fuel flow
• EGT
• N1
• Oil pressure increases
• Start valve closes
• IGN indication off (Refer to FCOM/PRO-NOR-SOP-08 AUTOMATIC ENGINE START ).
When the engine is at idle, or when AVAIL is displayed, the PF can start engine 2.
AFTER ENGINE START
Applicable to: ALL
The flight crew should check the relative engine vibration level.
When the ENG START selector is set to NORM, the packs return to the OPEN position. APU Bleed
should immediately be turned off, to avoid engine ingestion of exhaust gas.
If the start is not successful, the flight crew must use the ECAM as usually done, and avoid
instinctively selecting the ENG MASTER switch to OFF. This would interrupt the FADEC protective
actions (e. g. cranking after hot start).
AVERAGE IDLE ENGINE PARAMETERS

As soon as the engine-start is complete, the flight crew should check the stabilized parameters. At
ISA sea level:
EPR about 1.015, EGT about 380 °C, N1 about 23 %, N2 about 47 %, N3 about 63 %, FF≈ about
820 kg/h-1 800 lb/h.

As soon as the engine-start is complete, the flight crew should check the stabilized parameters. At

ENGINE START MALFUNCTION
Applicable to: ALL
Following an aborted engine start, the crew will consider an engine dry cranking prior resuming a
new engine start attempt. Starter limitations, Refer to FCOM/LIM-70 STARTER, must be observed.
