Abstract:This report presents the second part of our analysis of color use in Air Traffic Control displays. Part I of the study focused on operational displays, while this investigation focuses on auxiliary information displays with which controllers acquire additional information to make decisions. We chose three frequently used decision-support displays for the analysis. Those are: User Request Evaluation Tool (URET), Traffic Management Advisor (TMA), and Integrated Terminal Weather System (ITWS). For each display, we documented the background and default colors, color-coding, color usage, associated purposes of color use, and color complexity. With this systematic documentation, we were able to assess compatibility across displays. Using the color checklists we developed earlier, we also analyzed the effectiveness and shortcomings of color use in these displays. The results revealed a number of instances where the use of color might not be effective for its given purpose and where a color could have potential negative effects on task performance. The results of this study can benefit design prototypes and acquisition evaluation for new Air Traffic Control technologies.
