The Federal Aviation Administration (FAA) is deploying the En Route Information Display System (ERIDS) as an interactive electronic information display system to replace the current Air Traffic Control (ATC) information display system that consists mostly of paper materials. The purpose of this study is to research the benefits of ERIDS to controllers in terms of service efficiency and to the FAA in terms of potential cost savings of personnel labor. We visited the Jacksonville Air Route Traffic Control Center (ARTCC) where ERIDS is deployed and the Houston ARTCC where controllers are using paper reference manuals. We observed controllers during live operations, conducted a simulation to collect access times to ATC information, administered a questionnaire, obtained quarterly reports of ERIDS usage, and interviewed staff personnel who support both systems. Thirty-seven supervisors and traffic management coordinators participated in the simulation and provided questionnaire responses. In simulation, participants were generally not faster to access information using ERIDS compared to paper reference manuals. However, our simulation was limited in that all paper reference manuals were within reach of participants. In actual operations, ERIDS can be quickly accessed, whereas, it can take several minutes to find paper reference manuals. Interviews indicated that ERIDS can reduce the labor spent on disseminating paper reference materials.
