What are the primary differences between an automatic and manual start?
- Automatic Start: The FADEC provides full monitoring during start and will provide appropriate ECAM cautions and procedures to follow in the even of a start fault.

- Manual Start: Automatic start interruption and auto-crank are not available
With the ENG MODE selector in the IGN/START what occurs when you press the ENG MAN START pushbutton?
- The start valve opens

- Both pack flow control valves close
Will the start valve then automatically close?
Yes, at 50% N2
When would you use a manual start?
After aborting a start because of:
- Engine Stall

- Engine EGT overlimit

- Low start air pressure

When expecting a start abort because of:
- Degraded bleed performance due to hot conditions or at high altitude airports

- An engine with a reduced EGT margin in hot conditions or at a high altitude airport

- Marginal performance of the external pneumatic power group
