A320:
From Memory
Don't flame me:
Adjust attitude for 300 KTS for windmill start, IGN, cycle ENG MASTER S/W ON 30 SECS THEN OFF 30 SECS until start.
IF NO WINDMILLING START:
Two VERY important altitudes to remember, FL250 APU START(BATTERY) and FL200 APU BLEED ON for assisted START. Make sure ENG MASTER S/W have been OFF for 30 SECS and start ONE ENG AT THE TIME.
When you do the assited start you can reduce your speed to GREEN DOT for better glide.
It is all on the Airbus QRH.
