  flight deck—if something is dropped, retrieve it with minimal head movement and be alert for the coriolis illusion. Graveyard Spiral As in other illusions, a pilot in a prolonged coordinated, constant-rate turn may experience the illusion ... nose-low or dive attitude. A rapid deceleration by quick reduction of the throttle(s) can have the opposite effect, with the disoriented pilot pulling the aircraft into a nose-up or stall attitude. Figure 17-5.
