I am what is called a PS1 pilot so I am a little biased but …
The Aerowinx Precision Simulator (PS1) is not exactly a flight simulator (like the Microsoft flight simulator) but its more a flight trainer.
Only if you want to learn how to operate the B744, this is (and nothing else) the simulator you are looking for.
If you are interest in scenery outside the cockpit, this is NOT what you are looking for (although if you have 2 computers and you can connect them, you can run Microsoft Flight Simulator 2000 on a second computer and have the scenery). I guess you visited the entire Aerowinx web site so you know what is implemented and how it looks like.
Its almost the same thing to prepare the real aircraft for a flight (from the pilots point of view) and the simulator cockpit.
You can work almost an hour before you take off!
More than that, since its very precise simulator, it will take you some time to learn how to fly it (and I’m not talking about a few days), so if you are not MAD about the B744 (like me and others in the Aerowinx forum) you may find yourself frustrated very quickly and disappointment, so think very carefully about it (I thought 3 months about it).
But, after you will learn to fly it, you can go and fly a real full motion simulator (the same one that a real pilots are training on) without any problems. Personally I didn’t do it, yet, but others did (although after the Sep 11th I don’t know if it possible to do it any more).
Long live the B747
