Gx accelerations approximating those encountered in aircraft catapult launchings were generated on the human centrifuge Dynamic Flight Simulator at the Naval Air Development Center. Each of four catapult-experienced Naval aviators continuously oriented himself to the gravitational vertical both before and after exposure to the accelerations under two conditions: a) while he sat in total darkness, and b) while he viewed a small target projected at eye level in his mid-sagittal plane. The accelerations produce changes of pitch orientation that were affected by the presence or absence of the target, and the changes of orientation persisted well after the accelerations were terminated. Visual and postural illusions and their contributions to the disorientation are discussed, and the disorientation is related to certain water-collision accidents that have been reported to occur following aircraft catapult launchings at night.
在海军航空发展中心的人体离心机动态飞行模拟器上，产生了接近飞机弹射起飞时所遇到的G值加速度。四名有弹射经验的海军飞行员，在两种情况下，即在暴露于加速度之前和之后，都持续使自己相对于重力垂线保持定向：a）当他坐在完全黑暗中时；b）当他观看在他矢状面中眼平高度投射的一个小目标时。加速度产生的俯仰定向变化受到目标存在与否的影响，并且在加速度终止后很长时间，定向变化仍然存在。讨论了视觉和姿势错觉及其对定向障碍的影响，并且这种定向障碍与据报道在夜间飞机弹射起飞后发生的某些水上碰撞事故有关。
