EFFECT OF MULTI-SEGMENT FLIGHT ON PERFORMANCE AND MENTAL WORKLOAD OF STUDENT PILOTS: A STUDY ON FLIGHT SIMULATOR
In the world of aviation, sometimes pilots have to do short-haul flight (short distances) that allow pilots to do flight more than once (multi-segment flight) in one duty period. Pilots who carry out multi-segment duty day experience higher fatigue compared to pilots who only do one flight in one du...

| Summary: | In the world of aviation, sometimes pilots have to do short-haul flight (short distances) that allow pilots to do flight more than once (multi-segment flight) in one duty period. Pilots who carry out multi-segment duty day experience higher fatigue compared to pilots who only do one flight in one duty period. Many researches on multi-segment flight has been carried out on airline pilots, but not much research has been done on student pilots. Student pilots have less experience than professional pilots, besides the mental workload perceived by student pilots are higher than experienced pilots. This study aims to look at the effect of the first and second segments of flight on performance and mental workload aspects of student pilots. A total of 20 participants were divided into two groups, namely first-segment flight (FSF) and second-segment flight (SSF), carried out aircraft simulations for 45 minutes. Performance aspects are measured in two ways: subjective flight performance by the instructor and reaction time speed before and after simulation using psychomotor vigilance task (PVT). Mental workload was measured using NASA-TLX to see subjective mental workload, salivary Alpha-Amylase (sAA) enzyme levels to see stress levels, and the Karolinska Sleepiness Scale (KSS) sleepiness questionnaire to see sleepiness level. Based on the analysis using t-test and non-parametric test, the two flight segments did not affect the performance of the student pilots. Mental workload showed a large difference seen from stress indicators, stress levels were 89.5% higher before simulation and 112.2% after simulation for SSF. All performance indicators and mental workloads showed that decreased condition on SSF were worse than on FSF. From this study it can be concluded that multi-segment flights with two flight segments are safe enough to be carried out by student pilots. Further research is needed to determine the effect of flight with more segments. |
