仪表飞行条件下飞行错觉与仪表注视的相关分析

目的 分析仪表飞行条件下飞行错觉发生情况与仪表注视的相互关系。方法 对45名飞行员进行仪表飞行试验，记录其飞行错觉情况、仪表扫视情况及眼动情况，并对以上指标进行偏相关分析。结果 飞行员仪表飞行错觉水平与飞行错觉后反应（r=0.620,P=0.000）、升降速表注视时间（r=0.372,P=0.014）呈显著正相关；与高度表反应正确率（r=-0.304,P=0.047）、地平仪反应正确率（r=-0.311,P=0.042）呈现显著负相关。结论 飞行员仪表飞行错觉的发生与高度表、地平仪及升降速表的正确判读具有一定关联，视觉搜索效率较低可能是飞行错觉发生的重要原因或重要中介因素。

The relationship between flight illusion and instrument fixation under instrument flying condition

Objective To analyze the relationship between the occurrence of flight illusion and instrument fixation under the condition of instrument flight. Methods 45 pilots were tested by instrument flight, the flight illusion, the saccade and eye movements were recorded, and above indicators were analyzed by partial correlation. Results The pilot flight illusion level was significantly correlated with the flight illusion reaction (r=0.620, P=0.000) and lifting speed table fixation time (r=0.372, P=0.014); however, the flight illusion level also showed a significant negative correlation with the correct response rate of altimeter (r=-0.304, P=0.047) and indicator (r=-0.311, P=0.042). Conclusion The pilot instrument flight illusion has a certain relevance with correct interpretation and altimeter, horizon and lifting speed table. The low level of visual search efficiency may be an important cause or important mediating factors for flight illusion occurrence.
