This is an improved AFCAD for Florence Airport(LIRQ) Installation: Simply drop the AF2_LIRQ.bgl file into your Flight Simulator9, Addon Scenery, Scenery folder. FS will automatically recognise the file, and install it. Uninstallation: Delete the AF2_LIRQ.bgl file, and FS will revert to the default settings. Notice This file should not harm your computer in any way. I have all my afcad installed on my own computer and have tested them in Flight simulator 2004 numerous times without any problems. Nevertheless install at your own risk. I don't assume any responsibility for problems with computers.
