UTM Technical Capability Level 4 Testing

NASA's UTM project is conducting research on a traffic management concept for small unmanned aircraft systems (UAS) flying in low altitude, uncontrolled airspace. The project started in 2015 and is developing prototype UTM systems of successively complex technical capability levels (TCL) that are tested in the field. To date TCL levels 1-3 have been tested and TCL 4 will be tested in the summer of 2019. Project results are transferred to the FAA and industry to advance the adoption, implementation, and design standards of future UTM systems.
