m2f,
Yes, that is the system I am referring to, sorry if my last post wasn't too clear...
The C90A manual does not stipulate turning the generator off for starting the second engine. Indeed, when doing generator cross starts the current limiter is bypassed.
My question relates to generator assisted starts. In The King Air Book, Tom Clements suggests starting the second engine with both generators off, though once the N1 is through a certain value (not a book figure, just suggested) turning on the generator of the running engine. This will provide higher N1 and a cooler start.
He does say that this practice should not be used on the later models with the aforementioned electrial system. It seems a little strange to me that it is ok, as per the AFM, to do a cross start but not an assisted start. Any thoughts?
