My local airfield is not included in FS2004, I presume because it is so small. I would like to include it and upgrade it. By upgrade I mean outright copy another airport and paste it in the location where my local airfield should be. I have Aerosoft
You can't just copy and paste. You'd have to change the geographic locale as well or you'd just be pasting the airport over itself. Probably worth having a browse in the Scenery Design forum for some handy hints
There are two types of aeroplane, Spitfires and everything else that wishes it was a Spitfire!
Actually creating a whole new airport would be better than having to go through the process of moving an airport because that would involve useing AFCAD too. I can make you a the airport with almost anything you want in it.
