Qualitative Analysis on the Factors Influencing Pilot Functional Status

Objective—When the pilot's function status is low, he can't complete the task effectively, which may cause the whole system to malfunction or even cause serious accidents. So, in order to provide scientific basis for maintaining and improving pilot functional state, this paper studies the concept, connotation and influencing factors of pilot's functional state. Methods—Qualitative research methods were used, including literature analysis, questionnaire survey and expert interview. And 30 pilots were recruited to an in-depth interview. Results—There are three main factors that affect pilots’ functional status: special flying environment, physiological factors and psychological factors. Among these three factors, the perception ability, information processing ability, comprehensive cognitive ability and social psychological state of psychological factors are particularly important for flight function. Conclusions—The pilot's functional state directly affects flight safety. It is necessary to pay attention to the factors that may affect flight functional state, and to monitor the characterization of functional state regularly. Therefore, corresponding preventive measures can be formulated to reduce the potential risk of threat to flight safety.
