Initiate the subsequent start after the engine has completely spooled down. Do not complete
subsequent starts, until the vibration level is below 5 units. It is anticipated that the second start will
fall within the 5 units limit. This procedure may be repeated a maximum of three times.
In the log book report any N2 vibration advisory condition.
Use the automatic engine start procedure in most circumstances. However, if the start aborts due
to insufficient starter inlet air pressure (e.g. on high airfields, or in case of low pressure from an
external pneumatic power group), it is recommended to use the manual start procedure, instead the
automatic procedure.
If, during the engine start, the ground crew reports a fuel leak from the engine drain mast, run the
engine at idle for 5 min. If the leak disappears during these 5 min, the aircraft can be dispatched
without maintenance action. If the leak is still present after 5 min, maintenance action may be
required before the flight.
ENG MODE selector........................................................................................................... IGN/START
The lower ECAM displays the ENG SD page.
START ENGINE 2..............................................................................................................ANNOUNCE
Engine 2 is usually started first. It powers the yellow hydraulic system, that pressurizes the parking
brake.
ENG 2 MASTER sw..........................................................................................................................ON
Do not turn the ENG 2 MASTER sw ON before all amber crosses, ‐ except on N1 and N2, and
messages, have disappeared on the engine parameters (upper ECAM display).
‐ The N1 and N2 indications show amber crosses until the actual N1 and N2 reach about 3.5 %.
‐ Parameter callouts are not mandatory.
‐ In case the electrical power supply is interrupted during the start sequence (indicated by the loss
of ECAM DUs), abort the start by switching OFF the ENG 2 MASTER sw. Then, perform a 30 s
dry crank.

Note: When the FADEC detects an impending hung start or hot start, the FADEC applies an
automatic recovery sequence without an ECAM message. The crew will notice that dual
ignition (A+B) is applied, and that fuel will be commanded OFF, and then re-commanded
ON within 0.5 s. It is not necessary for the crew to shut down the engine.
�� When idle is reached (AVAIL indication is displayed):
MAIN AND SECONDARY ENG. IDLE PARAMETERS...................................... CHECK NORMAL
At ISA sea level : N1 about 21.4 %
N2 about 57.8 %
EPR about 1.01
EGT about 414 °C
FF about 350 kg/h (775 lb/h)
Grey background on N2 indication disappears.

Same procedure as for engine 2.
Both pack valves reopen with 30 s delay after the second engine N2 is above 50 %.
Note: A PTU FAULT is triggered, if the second engine is started within 40 s following the end
of the cargo doors operation.
