This study was a human factors evaluation of collocating User Request Evaluation Tool (URET), Core Capability Limited Deployment, Traffic Management Advisor, and Controller Pilot Data Link Communications (CPDLC), formerly Build 1A. Human Factors Specialists conducted the evaluation in two phases: a “paper and pencil” study - Phase 1 and a modified cognitive walkthrough - Phase 2. They examined the tools from existing documentation and system design in the context of human factors best practices. Four primary human factors issues emerged from this analysis: 1) Computer-Human Interface (CHI) inconsistencies; 2) Radar Associate (RA)-side collocation and timely access to information; 3) Communication of information between the RA-side and Radar-side controllers; and 4) National Airspace System updates from the different tools. Results include recommendations for human factors engineering for integrating the URET, CPDLC, and Computer Readout Display information on the RA-side, as well as working toward improving CHI consistencies.
