If one was to just start out with AI (have UT already)for when Vatsim has the vacancy sign out, what AI utilities/enhancements are a must have? I found AI Smooth to help with go-arounds but what other stuff is out there? Thanks

There is a feature of Ken Salter's FS9 Configurator that I found even more helpful that AISmooth for preventing go arounds. It provides a means to increase the AI aircraft rollout speed and taxi speed. This is great. The configurator is freeware (actually donationware, as I recall) and is available at www.kensalter.comYou may also wish to download Lee Swordy's Traffic Tools and AFCAD2 programs to finetune your traffic files. Those are available in the AVSIM library. R-
