Sorry, blaming the victim is not an effective support strategy for your proposal
. What you really need to do instead is support it with some kind of evidence for its efficacy. I don't mean to be quarrelsome, but the problem here is you're advocating an unusual shutdown procedure without also showing how/why it's better than the normal procedure that's been in use on these engines for decades already with no known ill effects.
If you can provide that support or even show how the normal procedure is defective compared to it, I'll be more inclined to look at it. But until then I continue to express skepticism that it's of any additional value.
The other problem is that it clearly introduces additional hazards that a normal shutdown doesn't, due to the skill and good timing with the throttle and ignition switch that seems to be required to carry it out. If it weren't for that, I wouldn't really be too concerned about it and probably wouldn't have ever typed anything.
But at 20 grand a pop, we need to experiment with our 912's only very carefully
Good luck with it tho. I'd be interested in what results you're getting 1500-2000 hours or more down the road.
