FAA and NASA lay groundwork for Unmanned Aircraft Systems September 6, 2019 The Federal Aviation Administration (FAA), NASA, and their partners in a pilot program that is laying the groundwork for an Unmanned Aircraft Systems (UAS) traffic management system, successfully demonstrated how such a system can work in the future. The demonstrations, conducted at 3 separate test sites selected by the FAA for the UAS Traffic Management Pilot Program (UPP), showed that multiple, Beyond Visual Line of Sight (BVLOS) drone operations can be safely conducted at low altitudes (below 400 feet) in airspace where FAA air traffic services are not provided. As demand for low altitude drone use increases, the FAA, NASA and the UPP partners are working together to accommodate these operations safely and efficiently.
