Evaluation of NextGen Air Traffic Control Alarms and Alerts Using Cognitive Walkthrough Method

摘要

In the air traffic control domain, there are no clear distinctions in the definition of critical safety messages,rnsuch as alarms and alerts. We therefore created a categorization scheme to distinguish alarms from the alertsrnand applied it to NextGen air traffic control systems: Standard Terminal Automation Replacement Systemrn(STARS), En Route Automation Modernization (ERAM), and Data Communications. Controllers thenrnevaluated the effectiveness of the alarms and alerts of these NextGen systems. We used CognitivernWalkthrough method with the “thinking aloud” procedure to collect their spontaneous and immediate evaluation.rnBased on these evaluations, we present recommendations for the future NextGen air traffic controlrnalarm and alert design.
