500TT and 55ME I'm not sure how comfortable I would be at 300 hours hopping into a 1900. At 450 hours when I started flying a King Air I was overwhelmed, but I had a great instructor who mentored me through the beginning hours. Looking at myself now I'm still a tad nervous with only 500 hours to be hopping into a 19 seat turboprop. I'm very thankful I was able to fly the King Air around as the two planes are nearly the same. In fact I don't know how I would have done in the sim eval had I never been exposed to that type of environment.
