The simulator does not produce the physiological disorientation that a real aeroplane does. Until this can be simulated accurately, instrument flying and unusual attitude recovery exercises in a simulator are a waste of time.
It is the lack of instrument pure flying skill in IMC that has caused the vast majority of loss of control from unusual attitudes. Physiological disorientation has nothing to do with it. If it were, there would hundreds of crashes every month from aircraft carriers on catapulted take off's.
