I have been wrestling with a minor problem for a few weeks now. I have been trying to get FS2K4 to drop the individual TRACONS (Approach/Departure centers) around the SFO area, and others - Bay, Sacramento, etc in favor of the new Norcal Approach/Departure, but have been so far unsuccessful. I have tried changing the callsigns in AFCAD, but it still insists on using Bay (or whatever). Is there anyway to get MSFS to use the changes, or am I just trying for too much realism (otherwise known as wasting my time)?

Hi,I think this would be a very difficult things to achieve. Do I understand it correct that you want to change the ATC center itself? These are defined somewhere in a default BGL file and can not easily be changed with AFCAD.Besides that you would probably get a problem with the sounds if you start new names not there in FS.
