Abstract |
This article describes 2 empirical studies?an initial study and an experiment?that investigate the impact of displaying resolution advisories (RAs) issued by the onboard Traffic Alert and Collision Avoidance System to the air traffic controller. The initial study served to assess and refine a method for evoking RA events in an interactive and realistic air traffic control setting. Using this method, an experiment was conducted to systematically assess the operational impact of RA downlink on the controller. The experiment provided evidence for operational benefits, namely a lower number of contradictory clearances to aircraft involved in an RA and a better recollection of RA events caused by pilot or controller error. Furthermore, there was no evidence for negative effects of RA downlink, such as cognitive tunneling on the RA event. |
