GA to heavies...

The Flight 1 ATR is an absolute favorite of mine. It looks intimidating with such a busy overhead panel, but you don't mess with any of it during flight, unless you need icing or to adjust the lights. I'm not one to start cold very often since it just takes time and isn't very interesting, however, the cold start on the ATR is easy, plus you have two ways to do it. The FMC on the ATR is very simple too. If you can learn the PMDG FMC, you can learn the ATR. I find very little difference. The nicest thing the ATR FMC has is the option for two flight plans, it comes in handy sometimes. Out of all my payware, I have to say the ATR is one of the best. It banks very well in a turn without pitching all over like some do. The Aeroworx King Air you mentioned is another one that allows a bank that's manageable in pitch. The ATR is a little easier to land though, as it's doesn't float as bad as the King Air.The PMDG 737, 747 and LDS 767 are obviously the best of the best Heavies for FS9. All have excellent flight dynamics and a easy to land, IMO. I find the PMDG 747 the easiest to land (I never use AP for approach) or at least control for ILS. For some reason it's really responsive without sensitive like a default Cessna ;) The 737 is a great aircraft, and the easiest of the three to learn. All good choices no matter what.
