Thanks MX Trainer. There is very little technical information about the PW100on the internet(hint hint).
I am curious what PWC did to make the PT6-28 engine different from the -27for the high altitude capability.
Hope I am not asking too many questions. It is just that I flew the DHC-6 with the -27 and the King Air with the -28(I think out BE-99 had it as well) and always wondered what the real difference was internally.
