'Jaba dabba do' yr too clever for us buddy
All combustion donks don't enjoy excessive heat especially during the start phase & a T/W strong enuf on a fan donk can actually turn the big fan up front backwards, not a good start to a start. As long as N2 is rotating/motoring max rpm & the big fan is going the right way then all things being = a good start should result:-)
All good answers here from those in the know but remember guys rather than bag the guy how about we all help, now wouldn't that be a novelty for pilots
None of us where born with any answers to any Q's, we learn & not just from the text books either
