Abstract

Observations of air traffic controller operating practices suggest that controllers operate in distinct operating modes in response to changes in the cognitive demands of the air traffic situation. These modes appear to correspond to differences in the use of structure-based strategies and abstractions identified primarily from rich but uncontrolled settings. In order to investigate the effects of manipulating traffic levels on controller use of structure, a part-task human-in-the-loop experiment was conducted. Participant actions are examined for changes in the use of standard flow and critical point abstractions and transitions between controller operating modes. The results provide evidence of transitions between distinct operating modes as participants modified their use of standard flows as traffic levels increased.
