Objective: The main purpose of this study is to determine the fatigue symptoms of pilots and to show how these symptoms trend according to flight types.Methods: Using a quantitative research design, the study collected data from 161 pilots working at three airlines in various regions of Turkey using a survey. Cross-tabulation analyses were conducted to examine the trend of fatigue symptoms across flight types; correlation analysis was performed to investigate the relationships between variables; and the Mann-Whitney U test was conducted to assess whether safety behaviour differs in terms of perceived adequacy of fatigue strategies.Findings: The results revealed that pilots most frequently experienced symptoms of sleeplessness and reduction of attention and concentration, with short-medium-haul pilots experiencing these symptoms more frequently depending on the type of flight. In addition to these findings, significant differences were found in safety behaviour averages scores depending on whether they perceived the organizations where pilots work's fatigue management strategies as adequate.Conclusion: Pilot fatigue has been found to manifest through a variety of symptoms, including sleeplessness, reduced attention and lack of concentration, small mistakes, difficulty perceiving messages from the tower, difficulty in decision-making, delays in response times, hormonal disorders, irritability, and decreased social communication, mini drops asleep. These symptoms are known to adversely affect critical human factor competencies. Given this established relationship, developing fatigue management strategies regarding flight planning are considered to be of great importance in mitigating such risks.
