Enhancing NextGen RNAV Capabilities: Human Performance Evaluation of NRS Waypoint Nomenclatures

As part of the Next Generation Air Transportation System (NextGen) initiative, a redevelopment of the high-altitude airspace is underway to realize the benefits of area navigation (RNAV) capabilities. Three nomenclatures were evaluated as possible alternatives to the current waypoint nomenclature used in the Navigation Reference System (NRS). A part-task study was conducted to assess if speed of NRS waypoint location on an en route chart, speed of flight management system (FMS) entry, number of FMS entry errors, and NRS waypoint reroute use were different among the nomenclatures tested. Overall preference was also assessed.
