I'm no expert, but I have taken an airplane (a twin turbo-prop) through the data collection process for stall buffets and taken a simulator through FAA approval (high level, full motion). The aircraft was definitely not stalled, nor does the simulator simulate a stall. Years ago I asked the sim experts (aero engineers) why they didn't model the stall phase. Their short and simple explanation when something like this: If you make a reasonably good paper airplane and throw it in the air, you can reasonably model it's flight. Now try throwing an unfolded sheet of paper in the air. Got any idea where it's gonna go or what it's gonna do? That's what it would be like trying to model a stall.
