Human-in-the-loop experimental research for detect and avoid

This paper provides an overview of a Detect and Avoid (DAA) concept developed by the National Aeronautics and Space Administration (NASA) for integration of Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS), and provides results from human-in-the-loop experiments performed to investigate interoperability and acceptability issues associated with use of the concept with these vehicles and operations. The series of experiments was designed to incrementally assess critical elements of the new concept and the enabling technologies that will be required.
