It is apparent from reading this forum that many of you are wasting time actually *flying* when you could simply don your virtual anorak and go plane spotting instead.As I write this I have my other machine running at x4 rate in slew mode with the viewpoint over Taipei international RCTP, watching the air/ground traffic movements. I have more than 400 aircraft available, so I see a lot of movements.
What do you need to do this?
1. Frame rate friendly aircraft. Lots at www.projectai.com, with a vast range of repaints.
2. Flightplans. Same site. Alternatively, worldai2.zip available at avsim has a lot of flightplans to get you started.
3. Lee Swordy's Traffic Tools to convert the flightplans to the traffic.bgl file that FS2002 needs. Available everywhere.
4. Lee Swordy's Afcad to give aircraft the extra gates they need. Lots of afcad data files available at avsim.
5. Thomas Molitor's AITM tool which among other things makes it easy to see a timetable for the airport you are watching. Available at http://www.molitor-home.de/FS/AITM/
6. The taxispeed utility (forgot the name, sorry) to speed up the rate at which aircraft clear the runway.
7. Lots of patience
In general things run fairly well, although occasionally bizarre things happen: aircraft disappear on landing, disappear just when they are about to leave the gate, do missed approaches for no reason, but hey, it wouldn't be Flight Sim without a few bugs built in.
Give it a try - it beats having to watch Landmark and Orbit all the time.
