Afcad has nothing to do with AI except for assigning parking spaces. TTOLS comes with a readme file I suggest you read it.
after you decompile the traffic.bgl file it will make two files one with the aiports & one with the flight plans. You can use the flight plans as a guide to ad your own ai flight plans.Afterwards you will need to recompile them into a new traffic file. Or you can go to
www.projectai.com& there you will find more AI traffic flight plans than you can imagine. I am currently using the delta airlines and luthansa cargo lines & believe me it makes plenty of ai air craft. MIND you though this will not add traffic to every airport in FS esp. the smaller ones 8)
