This document contains the Executive Summary of the final report for the USAF Test Pilot School Test Management Project Have Multi-path Escape Decisions Using Sophisticated Algorithms Have MEDUSA. The full report is available under USAFTPS-TIM-18A-02 from the USAF TPS, Edwards AFB, CA. The Have MEDUSA report documents results for testing a system for real-time automatic ground collision avoidance for performance limited aircraft. Testing was requested by the Air Force Research Laboratory, Wright-Patterson AFB, Ohio. The lead developmental test organization was the Air Force Test Center, Edwards AFB, California. The executing test organization was the 412th Test Wing, Class 18A of the USAF Test Pilot School, Edwards AFB. Testing was conducted from 5 to 18 September 2018 and comprised of 2 ground test hours and 11 sorties totaling 19.9 flight test hours. Overall, the Rapidly Selectable Escape Trajectory RSET system was assessed to be MARGINAL. The RSET system performance demonstrated the utility of using a multi-path collision avoidance system for performance limited aircraft. Path prediction error did not meet the specified criteria and was larger than expected for the 30-second path predictions however, at the maximum refresh rate of 12.5 Hz, the RSET system ensured terrain clearance in all cases tested.
