ooops, meant to say TTools........Seriously, what is this stuff about? Is this a way to control AI aircraft kind of like what FSTraffic used to do?

Yes. You can read the very complete manual for the details. You can also alter the routes AI traffic takes at airports using AFCAD and AddaGate. AFCAD comes with a very complete manual as well.Hope this helps,-- Tom GibsonCalifornia Classic Propliners: http://members.aol.com/tgfltsim/index.htmlAlcoHauler Locomotive Page: http://members.aol.com/alcohauler/home/alcohaul.htmlFreeflight Design Shop: http://www.freeflightdesign.com/ San Diego Model RR Museum: http://www.sdmodelrailroadm.com/Drop by! ___x_x_(")_x_x___
