Man the military has used these for a bit now had a friend when I was in the AF whose job was to maintain and run them. They have them for every aircraft and there is also one for the Abrams MBT saw that one on miliraty channel once for that each memeber of the crew has his own station and they are actualy seprate but linked so the driver drives the loader loads ect. the driver is even in a seprate device apart from the other 3 crewmen just like the real Abrams.
They can link them together too so several of these things can "fly" together.If you think about it even though very high priced a sim machine like that saves a lot of money when you take into account how much it costs to fly a real fighter we would do at the least 4 hours of maintance per 1 hour of flying time and JP-4 aint cheap. Still nothing like the real thing baby! Sometimes the Air Force will give an airman that does something outstanding what they call an "incentive ride" where they strap you in the back seat of a B/D or an older F-15E Strike Eagle model and take you for a ride if your really lucky you'll get to ride when they are running air to air they sometimes go all up to a 8 vs 8 scenario that is the one you want to go on because the pilot is going to pulling the full combat G's that he/she is used to.
