Methods Firstly, a scenario questionnaire that integrated the index factors influencing the visual judgment and operation deviation of the pilots during the landing was designed. Then the survey was implemented among experienced pilots, and entropy weight method was used to deal with 32 samples. Meanwhile, the questionnaire reliability and validity was analyzed. Results Five important factors affecting visual perception and judgment were visibility, navigation aids, flight experience, flight ability and ground visual references. The top five factors affecting manual operation in landing were flight skill, flight experience, wind speed, gross weight and configuration. Conclusion The most important task in landing for pilots is visually finding the runway and it is influenced more by air visibility and navigation aids. The adverse effects of the flight environment on the manual operation could be decreased through improving the level of the pilots operating skills. Keyword：
