- Glare is a threat to aviation safety, as it can changed the adaptation status and visual function of pilots during nighttime flying. The evaluation of discomfort glare has been hotly debated in the past decades. This article presents two experiments, with three visual task involved, i.e. reaction time, detection threshold and discrimination threshold, to inspect Lin-Liu model’s predicting effect of discomfort glare pilots encountered during nighttime flying, and also to explore how the discomfort glare affect the visual performance of the pilots. The results were analysed using repeated-measures ANOVA. It was confirmed that glare has a significant influence on the pilots’ visual performance: under harsh luminous condition, visual performance got worse significantly. The evaluation result using Lin-Liu model, which expresses the perceived discomfort glare by means of deBoer rating (RdeBoer), showed a regressive relationship between deBoer rating and visual performance, which indicated a good prediction capability of Lin-Liu model in the influence of discomfort glare.
