I am trying to modify the student pilot lessons to simulate pilot training at NAS Pensacola. I know how to open the .flt files and .abl files and have the ABL SDK which to some degree I understand. I also understand how to link the files. My question is and I have searched here and online. Is there an explanation of each category of the .flt file?...specifically what is [Track]? I understand just about all of the other areas. I am an accomplished FS9 commercial pilot and am sharing my knowledge with 3 students at my grand daughter's school 3 times a week. I have modified the [Tower] and put the Cessna on our OWN untowered airport. I am changing the aircraft to the T-6a in the Lessons and I am tweaking the aircraft parameters to exactly reflect the aircraft. Please help with .flt file.
