Goal: Reduce likelihood and severity of runway incursions and collisions • Enhanced Traffic Situational Awareness on the Airport Surface with Indications and Alerts (SURF IA) application established by RTCA Special Committee 186 • Safety, performance, and interoperability requirements (SPR) published 2010, DO-323 • Identifies potential runway conflicts within 3 nm of the runway threshold and 1000 ft above field elevation • Utilizes traffic surveillance information from ADS-B In • Generates indications and alerts for a Cockpit Display of Traffic Information (CDTI) • Same runway, very closely spaced parallel runway, and intersecting runway operating configurations • To prevent inappropriate crew responses during departure, indications and alerts inhibited above 80 kt
