Starter
Hi
How does the starter attach to N2 during flight, when N2 is rotating but not enough to proceed with a windmilling start?
I am talking about restarting an engine with pneumatic air from the APU.
I thought the starter would fail to attach to the high pressure section, because N2 is still rotating. (At low speed, but still rotating)
Do we have the risk to break the starter by doing this procedure?
Thanks!
