Classic British Flight Sim

I'm wanting to put a few helo spots on the scotflight version of prestwick airport & rename it, so it becomes HMS Gannet.
Is it possible to do that, as well as create an AFCAD so its a totally independant place?
What would i need to do?

Hi Mate,

I'm assuming this is for FS9? If so you can't overlay airports ontop of eachother which is a pain. You may get away with editing the existing Prestwick AFCAD so that it doesn't cover the area of Gannet. Then create a separate Gannet one and make sure they don't overlap. I don't know that it will work, but its the only way I can think of doing it. Make sure you back up the existing AFCAD before changing it ;-)
