Not sure if this belongs in the AFCAD /TTools forum but here goes:I am having a great time with the new AFCAD and TTtools for FS2004, all the small airfields can now have AI traffic, circuits etc. (even when they are surrounded by hills!) a great improvement on 2002.Now here's the problem, I have a runway which is about 200ft longer than the stock item, its a small strip and the AI planes have no problem backtracking and taking off properly (better than 2002), but I cannot persuade them to turn at the new longer runway, they still turn where the old runway finished.Tried exclude files (Defarea from Christian Fumey doesn't list a layer for runways) and moving start points etc etc, nothing seems to work.I think this is an exclude problem...Any ideas?Geoff

I found the problem, here's how it seems to work.If you do not make a turn around at the end of the runway the AI planes will make a very nice left turn and back on the runway, but at the location of the original runway end. To make a turnaround at the end of the new runway you must make a loop using "normal" taxiway links and nodes. (not a "apron" links - my problem!)Geoff
