A Sensitivity Analysis Method of Human Factors Measurement Tools in Pilot Distraction

Abstract

In the process of the pilot executing the flight task, the distraction will cause a decrease in the pilot's situation awareness. Seriously, it may cause an aviation accident. In the paper, based on experiments and statistics, the sensitivity of human factors measurement tools (human performance, questionnaires, and eye movement data) in the pilot distraction is analyzed. It can provide a basis for pilot distraction modeling. Specifically, in the experimental phase, participants are required to complete the flight task with three interference intensities (low, medium, high). In the data collection phase, the data of the human performance, questionnaires, and eye movement has been collected. In the statistical analysis phase, based on statistical methods such as ANOVA (one -way analysis of variance) and post hoc analysis, the sensitivity of the human performance, questionnaires and eye movement data at different interference intensities are explored. Finally, the experimental results shows that human performance, questionnaires, pupil area, PERCLOS (the percentage of eye closure), and fixation duration were sensitive, which are available for the analysis and modeling of pilot distraction.
