No matter what the folks at microsoft say, PC-based flight sims will never be that realistic.
Fortunately, however, Flightsim 2000 has a lot of hidden features and settings, and supports more realistic a/c. There are several sites on the net, notably <A HREF="http://www.flightsim.com" TARGET="_blank">www.flightsim.com</A> , which help you make FS2000 (and other) sims more realistic.
Hope this helps somewhat!
