Data indicates that over time, general aviation operators with Traffic Alert and Collision Avoidance Systems (TCAS) have consistently had a higher Resolution Advisory (RA) rate – an indicator of midair collision (MAC) risk – as compared to commercial (Part 121) operators. This report documents the methodology used to identify MAC risk areas within the National Airspace System. The results are intuitively displayed over sectional charts to help depict the particular locations or routes where collision risk may be more likely, along with a graph to illustrate the proximity of aircraft involved in these events. The GAJSC has made the report publicly available for awareness throughout the aviation community.
