I used to be really into downloading every single airplane I could. But lately, I've been enjoying the stock airplanes greatly - particularly the Orbit 737, and the Emerald Harbor Air Caravan. I took the Caravan out the other night, and used it to ply through overcast stratus with moderate icing. And I set visability to minumus and made it snow. Perhaps it's my own perverse sense of "what instrument flying really should be," but I had a lot of fun doing it. And the FS2k2 stock airplanes are so well done (I only have a few gripes - Caravan missing the OAT gauge, and no virtual cockpit for the Learjet, and a few others) that I'm finding that I am ignoring the airplanes that I've downloaded, and that includes a fleet of beautiful ERJs. Plus, it's nice that every airplane has a real checklist. It reminds me of flying the real things, which I suppose is the point.
Anyone else want to join the Orbit/EHA fan club?
