| Abstract | Disorientation caused by 'Coriolis' vestibular reactions has been cited frequently as a significant factor in flying safety. In addition, personnel who maintain rotating radar towers may also be adversely affected by 'Coriolis' problems. In the study, the direction, extent and intensity of the illusions produced by 'Coriolis' vestibular stimulation were investigated with subjects (a) in total darkness, (b) viewing simulated wing-tip lights and a rotating beacon in an otherwise totally dark room, and (c) viewing the simulated aircraft lights through a window in a luminous 'cabin' in an otherwise totally dark room. During 72 deg/sec rotation about the yaw-axis, lateral head movements of 30 deg produced mean verbal estimates of apparent 'diving' and 'climbing' sensations between 33.8-87.2 deg. Intensity ratings of the sensation of apparent displacement were greatest for the 'simulated aircraft lights' condition, and the relative intensity of sensation between one type of head movement as compared with another appeared to be affected by the visual surrounds. |
