FSX Scenery--Islamabad International OPIS V6. New Islamabad International Airport V5, Pakistan. Learning is a process, so I learned something and completely rebuilt it to improve frame rates. It's a complete airport; if you have previous version V5 then delete it and add this one. Waiting for your reviews, but please keep in mind that it's a freeware and I have spent a lot of time on it.
