There have been recent reports by pilots of apparent visual bending or bowing of instrument horizons during and immediately following ascending rolling maneuvers in the F-14 aircraft. The present study investigates the probability that normal reflex actions may partially account for the illusions cited in these reports. The results of this study suggest that the vestibulo-ocular reflex (VOR) can produce an apparent deflection of the instrument horizon (actually an apparent flicking back and forth) during and after roll maneuvers involving high peak angular velocities. This perceptual aberration could disturb a pilot attempting to use his instrument horizon and could lead him to suspect instrument malfunction. The reported distortions of the instrument horizon could be the result of the VOR, which tends to stabilize the eye relative to the Earth during angular acceleration of the head, and therefore reflexly displaces the eye relative to objects such as flight instruments that move with the head.
最近有F - 14战斗机飞行员报告称,在飞机进行上升滚转机动期间及刚结束后,仪表水平仪出现明显的视觉弯曲或弓形现象。本研究调查了正常反射动作可能部分导致这些报告中所提及错觉的可能性。该研究结果表明,在前庭眼反射(VOR)过程中及之后,当涉及到高峰角速度的滚转机动时,前庭眼反射会使仪表水平仪产生明显的偏移(实际上是明显的来回闪动)。这种感知偏差可能会干扰试图使用仪表水平仪的飞行员,并可能导致他怀疑仪表出现故障。所报告的仪表水平仪失真可能是前庭眼反射的结果,前庭眼反射在头部角加速度期间倾向于使眼睛相对于地球保持稳定,因此会反射性地使眼睛相对于诸如随头部移动的飞行仪表等物体发生位移。
