This study was conducted to support the development of Minimum Operational Performance Specifications for UAS Detect and Avoid traffic displays being developed by RTCA Special Committee 228.The experiment tested four different display configurations. Thesewere a baseline display, an indication of Closest Point of Approach (CPA), an avoidance area (blob) indication, and a banding display. Also manipulated in the study weretwo levels of pilot experience and two types of control interface.Analysis of the well clear violations showed a significant effect due to display type. Individual comparisons revealed that both the avoidance areaand banding displays significantly decreased the likelihood of violating well clear relative to the baseline display. Performance with theCPA display was not significantly different from the baseline display.
