I want to know, why AI aircrafts are not landing at one aieport. There are enough parking for them, but they approach above altitude and report go around to the ATC or the ATC tell them to go around. What things can cause this happens? Thanks.

From the FS2002 perspective, there are a couple of common problems. One is the presence of mountains/hills/elevated terrain in the flight path. This will cause AI aircraft to always come in too high in some cases. So, if your airport is nestled in a valley this is a likely source of your problem.If you are seeing this problem within 10 or 20 minutes of pressing the Fly Now! button, or of resetting time or AI traffic level, you may be a victim of the starting altitude problem. When an AI plane starts up in the air, it is always at its cruise altitude as specified in the Flightplan file. So, a plane which is within a few miles of the airport may be at 30,000 feet even though it expects to land in 5 minutes. It simply can't get down to the deck AND get its speed down quickly enough.

Hi,Another reason may be the flight dynamics being not appropriate for FS9. You have to know that Microsoft's FS is never backward compatible with itself, so, in this case the flight dynamics (which are critical) has changed. When FS9 came out most of the Project AI planes didn't land or showed a strange behavior. Only by adjusting the flight dynamics things were right again. For AI planes you can find the new FDE's on the Project AI site. You need to replace the .air file and a large part of the data in the CFG file.CheersRobert
