Spins and stalls are modeled correctly. As for the exterior, proper paint, reflections on all metallic surfaces and lens flares create a very immersive environment. I've never flown planes, but I drive cars. I expect the same would be true for flight simulations. Force feedback support.
Lets talk about a concrete example.
You are planning on including detailed scenery for the Dallas area. One of the tricky things, weather-wise, around that airport is wind sheer. Cross wind landings are definitely tricky, in all cities. You can adjust up to 3 cloud layers at varying altitudes and densities. Also, wind and wind gusts, variable directions, barometric pressure, dew point and other aspects of the weather that affect piloting are open to your input.
