failure, the start valve can be manually operated by a handle.
AUTOMATIC STARTING
Applicable to:
This sequence is under the FADEC’s full authority, which controls the :
‐ Start valve
‐ Igniter(s)
‐ Fuel HP valves.
It provides:
‐ detection of hot start, hung start, stall or no light up, and protection for starter reengagement speed
and time.
‐ FAULT announcement with specific ECAM message.
‐ Start abort on ground (high pressure valve closure, start valve closure, ignition stopped) and
automatic engine crank after start abort and control of any additional start attempts.
In flight, the FADEC will select a starter assisted airstart if N2 is below 16 %.
This sequence may be interrupted by selecting the engine master switch to OFF.
AUTOMATIC STARTING
Applicable to: ,
This sequence is under the FADEC’s full authority, which controls the :
‐ Start valve
‐ Igniter(s)
‐ Fuel HP valves.
It provides:
‐ Detection of hot start, hung start, surge, no light up or N1 rotor locked.
‐ FAULT announcement with specific ECAM message.
‐ Start abort on ground (high pressure valve closure, start valve closure, ignition stopped) and
automatic engine dry crank after start abort.
One further automatic start attempt will be initiated by the FADEC after cranking, except in case of
N1 rotor locked. If this start attempt fails, the start will be aborted.

In flight, the FADEC identifies the windmilling or starter-assisted airstart conditions, according to
engine parameters and the flight conditions.
This sequence may be interrupted by selecting the engine master switch to OFF.
Automatic start abort is inhibited on ground, when N3 is above 50 % or in flight.

Note: (*) If after 30 s the engine master switch is not ON, the pack valves will reopen.
(**) At first engine start, if after IGN/START selection no further action is applied, the ECAM
ENG page will automatically disappear after 30 s.
(***) If ENG START selector is not switched to NORM, the ENG page is automatically
replaced by the WHEEL page 15 s after 4th engine start.

MANUAL STARTING
Applicable to:
Manual starting is under limited authority by the FADEC which controls :
start valve opening when the ENG START selector ‐ is set to IGN/START and the MAN START
pushbutton is depressed
‐ high pressure fuel valve and operation of both igniters when the engine master switch is set to ON.
start valve ‐ closure and, on ground, ignition cut off at 50 % N2.
The FADEC provides a passive survey of the engine during the starting sequence.
On the ground, it will automatically abort the starting sequence in case of starting EGT limit
exceedance or starter reengagement speed exceedance.
The sequence may be interrupted :
‐ before engine master switch set to on by selecting MAN START pushbutton to OFF.
‐ after engine master switch set to on by selecting it back to OFF. In this case a dry crank shall be
selected by the crew.
Note: When the engine master switch is set to on, selecting the MAN START pushbutton to off
has no effect.
In flight, the FADEC always commands a starter assisted airstart.
MANUAL STARTING
Applicable to: ,

‐ start valve opening when the ENG START selector is set to IGN/START and the MAN START
pushbutton is depressed
‐ high pressure fuel valve and operation of both igniters when the engine master switch is set to ON.
