AFCAD files are .bgl files that start with "AF2", they contain airport data like runways, taxiways, etc. Author Lee Swordy created a small program called "AFCAD" that let you edit those files. That's why those files are called "AFCAD files", you can edit an airport like a CAD program.
Downloading new AFCAD files becomes handy when you need more parking space at an airport, or the layout of the taxiways is in inaccurate. Addon AFCAD files should be copied to "\Flight Simulator 9\Addon Scenery\scenery\" . For FS2004, we use AFCAD2 files. For example, a new AFCAD file for the Seattle Tacoma Airport could be named AF2_KSEA.bgl. When you've copied the new AFCAD file to the scenery folder in the Addon Scenery folder, the next time you start FS, the new airport data is loaded. Just remove the file if you want the default airport layout back.
