Sponsored by the Federal Aviation Administration (FAA), The MITRE Corporation's Center for Advanced Aviation System Development (CAASD) developed the Relative Position Indicator (RPI) concept. RPI is an automation concept to aid air traffic controllers in coordinating arrival traffic, reducing the need to vector for spacing during merging operations and, thus, retaining the benefits of Area Navigation (RNAV) and Required Navigation Performance (RNP) procedures. Using an RPI research prototype, CAASD has conducted Human-In-The-Loop (HITL) simulations with ATC specialists at Denver Terminal Radar Approach Control (TRACON) facility. Utilizing an eye-tracking capability, CAASD evaluated the change in attentional allocation between scenarios with RNAV procedures utilizing the RPI automation and with RNAV procedures alone. The eye-tracking analysis provides preliminary indications that RPI does change air traffic controller visual scanning patterns, likely resulting from the increased density of desirable information in a smaller region of the surveillance display.
