Abstract:
Objective To investigate the fatigue status and its characteristics and influential factors of military pilots. Methods Questionnaire survey was conducted on 924 military pilots by using Fatigue Assessment Instrument (FAI) and Fatigue Scale (FS-14), χ2 test and Pearson correlation analysis were performed on the data results with SPSS 17.0 software. Results The findings of fatigue status indicated 343 subjects (37.1%) with positive fatigue symptoms and 581 subjects (62.9%) with negative fatigue symptoms. FAI factor 1 (severity of fatigue), factor 2 (mental fatigue factor), factor 3 (consequence of fatique) and the total score, FS-14 factor 1 (physical fatigue factor) and the total score in fatigue-positive group were all higher than those in fatiguenegative group, and the differences were all statistically significant (P<0.01). The possibilities of developing fatigue symptoms for the subjects with different ages and flight time were statistically different (P<0.01, P<0.05); however, there was no statistically significant difference (P>0.05) in the possibility of developing fatigue symptoms between subjects with different aircraft types. Age and flight time were positively correlated with factor 1 and total score in FAI and factor 1, factor 2 and total score in FS-14. However, the aircraft type was associated with neither the individual factors and total score in FAI nor the individual factors and total score in FS-14. Conclusion It is common for military pilots to develop fatigue symptoms, characterized by obvious manifestations of severity, environmental specificity, consequences of fatigue and physical fatigue, and the possibilities of developing fatigue symptoms for different ages and flight time were different.
