Hi AirRabbit,
Anyone not located at either of those pilot positions ... may, at times, find that their inner ear (subject to the motion cues provided by the motion system) may not be completely “in-sync” with what images are transmitted from the eyes to that portion of the brain that is processing those external cues .... nonetheless, quite rare that a person occupying either of the pilot seats will experience any such anomaly...
There is very limited rotation of the simulator cabin in the horizontal plane (constant heading). During any taxiing where the visual and instruments show we've just completed say a 180 degree turn, even with a latency well within 100 ms, my inner ear tells me we have not turned and I feel nauseous.
Am I really "quite rare" or are there a lot more of us out there.
