I've got 2002...was thinking about upgrading to X for my birthday in a few weeks, but I'm gonna get a new camera instead.
I've only just started to land 747's - I started to use the speeds that were written just above the gear - but they were a bit slow - so you gotta watch it as you come into land, as you'll drop like a bloody stone if you're too slow.
Enjoyable. I only wish that add-on a/c had the full 360 flight deck like the ones which came with the game itself - and that they were the right ones...they use a 737 cockpit for an MD11...highly doubtful in real life, I'm guessing.
I was also told by somebody who's only ever piloted a glider that the control matrix was different to that of the real thing...but that might be because he's used to non-powered flight.
