Background: The pilot's performance cognitive is an important construct that plays a vital role in preventing aviation incidents. Various studies have identified factors affecting pilot cognitive performance, but there is a research gap regarding interaction of these factors and their sequence. Aims: The aim of present study was to develop a structural model for predicting cognitive performance of Iranian airline pilots based on the sources of stress and situation awareness considering the mediating role of mental fatigue and flight factors. Method: The method of present study was descriptive-correlational. The statistical population of study included all male civilian pilots working in Iranian airlines in 2019. Using a convenience sampling method, 310 people participated in the study as the sample. Research data were collected through Occupational Stress Inventory (Osipow & Spokane, 1998), Multidimensional Fatigue Inventory (Smets, 1996), Situation Awareness Rating Technique (Taylor, 1990) and performance evaluation in flight simulation environment and analyzed using structural equation modeling method and bootstrap test in Amos-21 software. Results: The results showed that the hypothetical research model with some modifications had a good fit. The fit indices of the final model included TLI= 0.91, CFI= 0.93, IFI= 0.93, GFI= 0.93, SRMR= 0.056, RMSEA= 0.055. The results also showed that occupational stress affects cognitive performance through mediating role of mental fatigue. Situation awareness also affected cognitive performance by mediating role of mental fatigue and flight factors. Conclusions: Based on the results, it can be concluded that pilots who have less occupational stress and mental fatigue, more situation awareness of and a high level of flight factors show better cognitive performance.
