Spatial-D, derived from physical cues sent by the inner-ear, can be a physically overwhelming experience.
Your body screams at you that you are at such-and-such an attitude and your body fights your mind. Your rational mind says one thing (trust the instruments) but your body fights back—hard.
It takes extreme will-power and discipline to trust your instruments and win the fight with your body. That is why an instrument license is issued. . .to certify those that are rated to fly under IMC conditions. Add bad weather and/or an indefinite horizon and other misleading visual cues and you are in for a world of hurt.
Experienced and inexperienced pilots suffer from spatial-d. Not all survive.
(Close your eyes, spin in a circle for a few turns and then open your eyes and try and walk a straight line. Same sort of thing you are dealing with.)
I’ve experienced some of that while flying. Very weird to say the least!
Well said. Who ya gonna believe, your lying middle ear or your own eyes.
