MANUAL ENGINE START
Applicable to: ALL
The flight crew should only perform a manual start if:
? The EGT margins are low
? The residual EGT is high
? A dry crank is performed.
It may be appropriate to perform a manual start in high altitude operations, or after an aborted engine start.
The MANUAL ENGINE START procedure is a "read and do" procedure.Refer to
FCOM/PRO-SUP-70-A MANUAL ENGINE START - MANUAL ENGINE START PROCEDURE before starting a manual engine start.
The FADEC has limited control over the manual start process. It ensures that the engine start valve closes at 50 % N2. It monitors engine parameters, and generates an associated warning when necessary.
It is recommended that the flight crew use the stopwatch to ensure that the starter engagement time remains within the limits.

TAILPIPE FIRE
Applicable to: ALL
An engine tailpipe fire may occur at engine-start, and may be the result of either excess fuel in the combustion chamber, or an oil leak in the low-pressure turbine. A tailpipe fire is an internal fire within the engine. No critical areas are affected.
If the ground crew reports a tailpipe fire, the flight crew must perform the following actions:
? Shut down the engine (MASTER switch set to OFF)
? Do NOT press the ENG FIRE pushbutton
? Crank the engine, by using either the bleed of the opposite the engine, the APU bleed, or external pneumatic power (Set ENG START selector to CRANK, then set the MAN START switch to ON).
Do NOT use the ENG FIRE pushbutton, this would stop power to the FADECs, and would stop the motoring sequence. The fire extinguisher must not be used, as it will not extinguish an internal engine fire. As a first priority, the engine must be ventilated.
If the ground crew reports a tailpipe fire, and bleed air is not readily available, a ground fire-extinguisher should be used as last resort: Chemical or dry chemical powder causes serious corrosive damage to the engine.
ENGINE WARM-UP PERIOD
Applicable to: ALL
After engine-start, and in order to avoid thermal shock of the engine, the engine should be operated at idle or near idle (Refer to FCOM/PRO-NOR-SOP-09-A AFTER START - ENG START SELECTOR) before setting the thrust lever to high power. The warm-up can include any taxi time at idle.
AFTER START FLOW PATTERN
Applicable to: ALL
When the engines have started, the PF sets the ENG START selector to NORM to permit normal pack operation. At this time, the After Start Flow Pattern begins.
