Dan you have the advantage on me having flown the jetstream but i have flown two turboprop transport types and have to say that when an engine fails on a light twin it takes much more skill to fly as the performance is so marginal.
This course can only teach the basics of multi engine flying and the military flying would have to be on another type ,my comments on improving training standards are only based on the asumption that the more types that one has flown the deeper your knowlage and experience it was not ment as a slur on the RAF multi engine training system.
