Your comment points out just how far behind today's capabilities the military is -- mostly due to their antediluvian, slower-than-cold-molasses procurement practices.
My simulator software is so old that it is no longer in production (and the company may be defunct). I run it with three monitors (one for forward/HUD view, and two for side views (of amazingly detailed terrain and target/combat scenarios). You can select a widely varied armament loadout (and experience the matching weight/performance effects). Of course, you can select for time of day, weather, etc.
It even includes the effect of reduced air density near the hot desert surface. The only real effect it lacks is the reverse thrust, smoke, and vibration when the GAU-8 fires.
And it's only a game -- playable on a laptop...
You got the pedals and trim wheels and everything?
