The Effects of Phases of Time on Pilot Mental Workload in Terms of the Differences Pilot Age

Abstract

The difference of phases of time condition can affect a pilot's mental condition. Regardless of the factors which the human body has a habit of working time and rest so that will affect the physical condition, and ultimately also affect the mental condition and vice versa. The study was conducted to determine whether such a difference in mental workload on the pilot to fly a different phases of time when operating the aircraft in terms of differnces pilot age. Mental workload measurements performed using the Subjective Workload Assessment Technique (SWAT) method, this method using combine of three dimensions with their levels. The dimensions are time load, mental effort load, and psychological stress load. The results of studies shows that the condition of mental workload experienced by pilots refers to phases of time (on average) is in the high category (overload). While the overall showed that more pilots emphasize time factor in considering the factors of mental workload. The most burdensome conditions of a flight for group one consist of 26 respondent (pilot age < 30 years) when the pilot was conducted in the morning, on weekends and during peak seasons, while for group two consist of 26 respondent (pilot age ≥ 51 years) is when the pilot was conducted in the early morning, on weekends and during peak seasons.
