Effects of Fatigue and Tension on the Physical Characteristics and Abilities of Young Air Traffic Controllers

The purpose of this study was to analyze the effects fatigue and tension on physical characteristics abilities air traffic controllers (ATCOs) determine their influence mechanisms. A simulated experiment designed evaluate responses ATCOs in four states: alertness, fatigue, tension, tension. Thirty young male participated experiment. Fifteen parameters were collected analyzed estimate decreasing order indicators. results showed that most significantly affected by attention, perception, reaction time, decision-making ability, comprehensive performance adversely had negative performance. Fatigue impair ATCOs. Both states initially then impaired abilities. However, mechanisms involved different. primary effect state slowing down, whereas tense instability. These provide a reference for evaluation management
