I am about to re-install fs9 because I was having problems with FSDT KORD, the dreaded ctd involving G3D.dll and mfc70.dll. I believe the ctd was caused by an overlap of AFCAD and ADE that I tried to use to get ai aircraft off the runway quicker at departure. I had read a post somewhere that upgrading AFCAD would reduce time ai spent getting off the runway. Too often an ai would get clearance for takeoff, taxi onto the active runway, and then creep....creep....creep....until finally stopping, then begin the takeoff roll. Of course the aircraft arriving, who was 9 miles out on final now has to go around because it took this departure so much time to get going. I see it most with the heavier aircraft, not so much with ERJ or CRJ. Questions:1. Should I use ADE or AFCAD to for airport changes? I am using fs9...2. Will ADE reduce the creeping of departures, or is this a problem solved in the braking section of the aircraft.cfg file?3. By exclusively using either AFCAD or ADE will this eliminate the ctd of G3D.dll and/or mfc70.dll?Thanks in advanceJohn
