I currently have 54,287 flight plans in my Flightplan.txt file (mostly Project Ai). I just finished downloading Ultimate Traffic. Should I delete the current flight plans before activating Ultimate Traffic or leave them in place and activate Ultimate Traffic? I do not want a bunch of duplicate flightplans.Anybody have any cons or pros?

You can post questions at their web page forum. But, UT will generate its own traffic.bgl file. It will not import any of your current flightplans or aircraft. You can do that with the built in features UT has on its GUI. See the forum for more detailed info and don't forget to RTFM!!! Enjoy, I love it!Tony
