Abstract: To reveal the correlation between fatigue, workload and human errors in the context of air traffic control, empirical study is conducted in simulated tower control environment, in which subjects are selected and observed. Two levels are set for fatigue and workload, and errors of each subject are acquired in observation. Results show that the amount of human error increased in high level of fatigue and workload, there is no interaction identified between fatigue and workload; and the chance of making errors increased in high level of workload. It is concluded that human errors are associated with fatigue and workload. Fatigue and workload should be properly controlled as for seeking the best performance.

Key words: air traffic controller, human factor incident, fatigue, workload, ANOVA
