If you need help there's a whole forum dedicated to it here at simV called 'AFCAD and TTools', good luck

.
PS. there's a program called Airextt which finds the planes speed and design name for you, you just copy the information it gathers from the generated Aircraft.txt into the TTools Aircraft.txt and all the infos there for you to make the flightplan. It makes it alot easier. (well it did for me)
