I've got a manual for TRACON here.
If you e-mail me at
[email protected] with your address, I'll try and scan in the bits you need and send them back.
We don't rate TRACON very highly, and chucked it in a cupboard. Ditto ATC SIMULATOR, which has a pants 'Voice recognition' feature, which only recognises US citizens.
TOWER was a reasonable attempt at aerodrome control, which doesn't give you a true impression of controlling airport traffic, but does give you an idea of how busy life can get. There are a few sites offering it as a download, but I don't know if they will include manuals or not.
ATC is a good place to work [even allowing for some of the issues with 'company stuff'], so follow all the advice given in the links at the top of the forum, and maybe you'll be doing it for real sometime soon.
