Does anyone know where the list of ATC Call signs that can be used is held in FS2004. I know there is the Airlines file in the FS2004 Aircraft folder , but that seems only to accept certain names e.g. it will accept "Air Force" and "Speedbird" but will not work for say "Military" or "Royal Air Force".
Under [General] in an Aircraft file you can input certain atc types , such as "Supermarine", "Helicopter" and of course "Cessna" etc, but where is the list of atc types kept . How can you add to it or modify it or what are the rules about using a new type?
