  • Abstract:
    Previous research in the domain of air traffic control (ATC) has explored factors that describe the complexity facing a controller.

    Based on this research, new technologies and procedures have been developed that may aid the controller and reduce the complexity in

    ATC. Most of these technologies were designed to reduce ATC complexity associated with air traffic density, identification and

    resolution of conflict situations, and the operational efficiency of the human-machine interface. The purpose of the present study was

    to explore and prototype new display enhancements that may reduce complexity in ATC. A team of researchers from the Human

    Factors Branch (ACT-530) of the Federal Aviation Administration William J. Hughes Technical Center and the Human Resources

    Research Division (AAM-500) of the Civil Aeromedical Institute (CAMI) identified four complexity factors as being suitable for a

    graphical enhancement. These factors were the effects of weather on airspace structure, the effects of active Special Use Airspace

    (SUA), the effects of the number of transitioning aircraft, and the effects of the reliability of radio and radar coverage. We conducted a

    user evaluation of the display enhancements and their possible impact on ATC complexity. Two supervisors and 13 Full Performance

    Level controllers from the Jacksonville Air Route Traffic Control Center participated as observers in this evaluation. The results of the

    user evaluation showed that the controllers supported earlier research that identified weather, SUA, transitioning aircraft, and reliability

    of radio and radar coverage as factors that increase ATC complexity. The controllers favored the proposed display enhancements.

    More importantly, the controllers predicted a substantial reduction in their job complexity from the enhancements. Based on these

    findings, we recommend a formal test simulation of the proposed enhancements to determine their efficacy for reducing task

    complexity in ATC operations. We also recommend further studies to determine the optimal colors for each display enhancement for

    use in operational systems.
