My Own Recent Experience
I have recently been transitioning from the Cessna 421 up to the Beechcraft King Air, at Flight Safety International, where I am an instructor. Even though I have previous experience flying turbine powered aircraft, it has been a few years. I have become comfortable with the Cessna 421. Now I am once again stepping out of my comfort zone in one aircraft and stepping into another aircraft. I have had to go back and get re-acquainted with turbine procedures I have not used in a few years.
