Effect of Aircraft Cabin Low Illumination on Visual Ergonomics of Pilots

目的研究飞机座舱低光照度对飞行员视觉工效的影响,确定飞行员视觉工效最佳的低光照环境。方法采用客观实验与主观量表相结合的方法对12名被试进行试验。结果被试在视觉实验过程中,实验结果受光照环境的影响。反应准确率最高、平均注视时间最短、主观评价得分最高的均为50Lux的光照环境,反应时间最短的是10Lux的光照环境,眼跳速度最快的是30Lux的光照环境。视觉工效综合评价的结果表明50Lux时视觉工效最佳。结论飞机座舱不同的光照度对飞行员视觉作业的结果存在一定的差异性,相对而言,50Lux的光照环境对飞行员的视觉工效最佳。

Objective To study the effect of low illumination on the visual ergonomics of pilots, and to determine the optimum low illumination environment for the pilot~ visual ergonomics. Methods 12 subjects were tested by the method of objective experiment and subjective scale. Results the process of visual experiment, the experimental resuits were affected by the light environment. It was the 50Lux light environment that the accuracy rate of reaction was the highest, the average fixation time was the shortest and subjective evaluation score was the highest. The shortest reaction time was the 10Lux light environment. The fastest saecade speed was the 30Lux light environment. The re- suits of the comprehensive evaluation of visual ergonomics showed that 50Lux was the optimum low illumination envi- ronment for visual ergonomics. Conclusion There were some differences in the results of different illumination on the pilot＇s visual work. In contrast, the light environment of 50Lux was the optimum low illumination environment for the pilotvisual ergonomics.
