Popis:	There is a growing consensus concerning the negative consequences of inappropriate workload on employee’s health and the safety of persons. In a simulator study, we focused on air traffic controllers during arrival management tasks. Our aim was to find out if the number of aircraft or the occurrence of an exceptional event added load to the subjectively experienced workload. The workload was assessed using the NASA-TLX, instantaneous self-assessment (ISA) questionnaire, and expert ratings. Our sample consisted of 21 subjects. According to standard ANOVA procedures, controllers’ subjective ratings showed a high-significant discrimination between the different air traffic demands but only a weak-significant discrimination between sessions with and without event. In particular, we were not able to obtain a significant interaction effect between traffic volume and event. However, the examination of between-subject factors could reveal additional information about controller’s rating behavior. We currently conclude that while the effect of the number of aircraft was evident, the impact of an exceptional event remained doubtful.
