how about the addon static or dynamic aircraft because the pics doe show like lots of american airlines or other airlines parked of taxing at jfk.
Screenshots shows the scenery with a Traffic package addon installed, which is how most of the people use FS with anyway. The scenery itself doesn't come with any included aircrafts parked, not static nor dynamic, it doesn't really make any sense to include static planes that take valuable parking spots, when most of the users would get rid of them anyway, to use it with a proper traffic package.
You can find plenty of traffic addons, both commercial, like Flight1's Ultimate Traffic, Aerosoft MyTraffic, Justflight's Traffic, or free like WorldOfAI. We are quite happy with the free WorldOfAI, although it can be complex to install, because you need to download separately all the arlines you are interested to. Commercial package usually are much easier to install.
