Internal and external risk factors analysis on pilot precondition in Indonesia.

Background: Pilot errors and preconditions are major concerns that affected by multiple factors physiologically, psychologically and psychosocially. This study aimed to analyse the correlation between the internal and external risk factors, and pilot preconditions in Indonesia.

Methods: A cross-sectional study design with purposive sampling, directed to male pilots who had flight duty in the past seven days, underwent medical examination at the Aviation Medical Center, Jakarta, August 12-16, 2024. The data were collected through a self-report questionnaire, Trail Making Test A and B, laboratory tests (plasma lipid, fasting blood glucose), and physical measurements (height, weight, waist circumference, and blood pressure). The independent variables divided into internal factors (Age, Burnout, Metabolic Syndrome parameters); and external factors (Flight Time, Duty Time, Unscheduled Flight Duty, Number of Sectors, Sleep Duration). The dependent variables were pilot preconditions based on the Human Factor Analysis and Classification System (HFACS).

Results: A total of 122 participants participated and 28.7% had an Unscheduled Flight Duty in the last 30 days. Significant correlations were found between Adverse Mental State and HDL-Cholesterol (95%CI=1.52-5.80), Adverse Physiological State and Burnout [Personal (95%CI=0.005-0,04), Work-Related (95%CI=0.009-0.042)], Physical Mental Limitation and Fasting Blood Glucose (95%CI=(-0.479)-(-0.071)), Number of Sectors (95%CI=0.022-3.001). For Personal Readiness (PR), significant correlation was found between PR-Psychological Demand and Flight-Time One Year (95%CI=(0.000-0.001), Sleep Duration (95%CI=(-0.137)-(-0.013)), Waist Circumference (95%CI=(-0.014)-(-0.002)), PR-Social Support and Sleep Duration (95%IK=0.018-0.207), Client-Related Burnout (95%IK=(-0.011)-(-0.002)).

Conclusions: The internal factors that correlated with pilot preconditions in Indonesia were Waist Circumference, HDL-Cholesterol, Fasting Blood Glucose, Personal Burnout, Work, and Client-related burnout. External factors that correlated with pilot preconditions were the Number of Sectors, Flight-Time One Year and Sleep duration. These findings emphasize the need to address physical and mental health aspects of pilots to enhance aviation safety.
