ABSTRACT

Purpose Establish evaluation index system and weight determination of fatigue risk factors of civil aviation pilots. Methods Questionnaires of flight pilots fatigue were issued to 291 pilots of an airline company in China and the influencing factors of pilot fatigue were analyzed by single linear regression method. By means of theoretical analysis, expert survey and issuing questionnaires to civil aviation pilots of all ages, various factors affecting the fatigue risk of civilian pilots were summarized. According to the comprehensive analysis of fatigue influential factors, taking 5 factors as the criterions, a pilot fatigue risk comprehensive valuating index system was established. Then order relation analysis method (G1 method) was used to calculate the weights of indexes. Results According to the established comprehensive evaluation index system, influence factors of pilot fatigue from heavy to light are respectively work factors, sleep factors, environmental factors, psychological factors and physiological factors. Conclusion Comprehensive quantitative evaluation system completes the qualitative and quantitative analysis of flight fatigue, which can be used as the basis for further quantification of fatigue risk.
