A320 starter limitation
 

Hi
Lets say the fadec turns the engine for two and a half minutes with the starter valve open due to a hot start as ive seen on the simulator. In such a case how do we continue to deal with the remaining start attempts?
Thanks

IAE 2527 A5 i think

The starter limitation was exceeded by 30 sec, what do we follow now. Is it ok to split the 4 minutes of continous cranking and use them for another start attmpt?
Why is the fadec exceeding the starter limitation to perform a dry crank.

Hi
Probably to protect the engine.

After a hot start, the FADEC will crank the engine until the EGT is below a certain threshold. If it requires a slightly longer cranking time than the starter motor limitation, then it is still the cheaper option. (Life of starter motor has probably been reduced).

In your example, I'd pause for at least 20 secs before the next start attempt, and limit myself to only 3 consecutive cycles before the 15 mins cool down. I'd make a tech log entry "starter motor cranking limit exceeded by 30 secs on first attempt" or something like it.
Edit (CFM engine limitations - don't have IAEs)

The way I would interpret it-
You have one last attempt left after 15 secs of pause- (max 1min 30 secs cycle).
If no joy, 30min cooling, call up maintenance.
Good thing not to interrupt FADEC even it exceeds crank limit.

I see

Well our IAE's are

2min on 15sec off / 2min on 15 sec off / 1min on 30mins off
Or 4 min continuous cranking 30 mins off
