A Comparison of Two Terminal Area Detect and Avoid Well Clear Definitions  (2019)
Abstract Header
Unmanned Aircraft Systems (UAS) Integration into the National Airspace System (NAS) Project.

- Researching how to overcome technical barriers associated with the operation of UAS in civil airspace [above 500ft AGL]
- One emphasis has been on the development of Detect and Avoid (DAA) technologies and procedures

A DAA system would allow UAS to comply with the ‘see and avoid’ requirements [14 CFR Part 91] in manned aviation

- The requirements authorize manned pilots to maneuver off their route to avoid potential/perceived collision hazards; i.e., maintain well clear
