Well if a metro can take 25kts then thats all it can take airframe. In your previous statement you put less than <5700kg so most types below this wieght can use the unsealed runways subject to the flight man or ops man. Yes i do only fly a piston & im not an instructor. Congrats to ya for flying a turboprop - you are my hero. You can say what ever you like about me only flying in my piston but we all usually fly pistons before turbines. I go by the rules like the most of us, sounds as if you may bend them just to get in, do you go below minimums as well?. Must be a o'connor vs rex thing happening here.
