Doubling the task - Effects of task switching during simultaneous control of multiple airports

Schneider, Norbert and Möhlenbrink, Christoph and Andrea, Kiesel (2011) Doubling the task - Effects of task switching during simultaneous control of multiple airports. HFES 2010, 13.-15. Okt. 2010, Berlin.



Research on remote tower control solutions for small airports raised the question whether it is possible for an air traffic controller to control multiple airports simultaneously. This simultaneous control would require the air traffic controller to switch between task sets of two airports. Therefore it is important to analyse the factors influencing task switching in these dynamic multiple task environments and how they are affecting the air traffic controller. A human-in-the-loop microworld simulation was conducted (N = 24, student sample). In the experimental conditions the task set was either the same (two airports with the same layout, global task repetition) or different (two airports, different layout, global task switch). It was expected that global task switch would lead to a decrease in task performance and increase of workload compared to global task repetition. Performance data, ECG data, eye data and questionnaires were analysed. Analysis revealed no significant influence of global task switching on dependent variables compared to global task repetition. However, local task switches (i.e. switches from one airport to the other) revealed a significant influence on mean reaction times. Participants responded slower when they switched between the two airports independent of the experimental condition. Additionally the analysis revealed a significant influence of training on dependent variables.
