Engine Start Flashcards
Use the automatic engine start procedure in:
Most circumstances.
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 of the automatic procedure.
AUTOMATIC ENGINE START.
ONE ENGINE TAXI PROCEDURE:
APPLY.
Apply the one engine taxi procedure from the QRH for all departures unless operational requirements or regulations dictate the use of both engines.
AUTOMATIC ENGINE START.
ENGINE MODE selector:
IGN/START.
The lower ECAM displays the ENG SD page.
AUTOMATIC ENGINE START.
ENGINE 2 START:
ANNOUNCE.
Engine 2 is usually started first. It powers the yellow hydraulic system, that pressurises the parking brake.
AUTOMATIC ENGINE START.
ENG MASTER 2:
ON.
- Do not set the ENG MASTER 2 lever to ON before all amber crosses, except on N1 and N2, and messages, have disappeared on the engine parameters (upper ECAM display).
- Parameter fallouts are not mandatory.
- In case the electrical power supply is interrupted during the start sequence (indicated by loss of ECAM DUs), abort the start by setting the ENG MASTER 2 lever to OFF. Then perform a 30s dry crank.

Bleed pressure indication green.
Oil pressure increases.
ON ECAM UPPER DISPLAY:
30s after ENG 2 MASTER sw is ON, FF increases.
ON ECAM LOWER DISPLAY.
Indication of the active igniter (A or B).
ON ECAM UPPER DISPLAY.
20s (maximum) after fuel is on:
- EGT increases.
- N1 increases prior to 34% N2.
ON ECAM UPPER DISPLAY.
At 43% N2:
ON ECAM LOWER DISPLAY:
Igniter indication off.
ON ECAM UPPER DISPLAY.
Slightly above 43% N2:
ON ECAM LOWER DISPLAY:
Start valve crossline.
When the FADEC detects an impending hung start or hot start, the FADEC applies an automatic recovery sequence without an ECAM message.
Th crew will notice:
That dual ignition (A+B) is applied, and that fuel will be commanded OFF, and then re commanded ON within 0.5s.
It is not necessary for crew to shutdown the engine.
When idle is reached (AVAIL indication is displayed).
ENG IDLE PARAMETERS:
CHECK.
At ISA sea level: EPR 1.01 N1 about 21.4% N2 about 57.8% EGT about 414 C FF about 350 kg/h
A PTU FAULT is triggered:
If the second engine is started within 40s following the end of the cargo doors operation.
