The Federal Aviation Administration is developing the En Route Automation Modernization (ERAM) system to replace the legacy en route air traffic control automation system consisting of the Host Computer System, the Display System Replacement (DSR), and the User Request Evaluation Tool (URET). This technical note provides an analysis of major areas where new ERAM features may affect how controllers do their jobs. We describe test methodologies for examining these effects and corresponding metrics. Our analysis examines the following categories of ERAM changes: (a) backup and redundancy capabilities; (b) Areas of Interest (AOIs) that increase flight data capabilities in ERAM; (c) differences between the legacy system and ERAM user interfaces (UIs); (d) the ERAM tracker; and (e) safety alerts. We also discuss two recommended test activities: a usage characteristics assessment and human-in-the loop baseline simulations.
