FSX Deluxe includes over 24,000 airports across the globe and features 45 “high-detail” airports that are spectacularly detailed. Users will recognize the trademark features at these high-detail airports and, having visited quite a few of them in real life in my flying career, I was suitably impressed with the attention to detail. Although they don’t approach the extreme level of detail of payware add-on airports that have been made for FS9 by companies like Imagine Simulation, they are quite good and many users might be completely satisfied enough to not add-on 3rd party environments (though the quest for add-ons is a bit of an addiction). The buildings and terminals at the high detail airports are pretty good, but even at the highest detail level the textures are a bit blurry, so I’m sure the 3rd party development world is safe.
