Seeing and avoiding are among the primary concerns surrounding unmanned aircraft systems (UAS), or drones. The JUATT system is similar to how air traffic control (ATC) currently service visual flight rules (VFR). Each UAS operator would file a proposed flight plan that requests permission to occupy an area of airspace up to 400 ft. above ground level using the grid system. This plan is reviewed by an unmanned controller who will either approve or deny the requested airspace. UAS operators then communicate with the unmanned controllers via text chat which helps reduce the cost of operations and allows ground based operators to communicate easily without radio interference.
According to the team, nothing like this currently exists. "Our system is different because it uses a grid reference system instead of fixes, waypoints, ground navigation aids, or latitude and longitude," said Jennah Perry, Professor of Air Traffic Management.
The JUATT system would allow for commercial UAS flights to be approved in a much more traditional manner by allowing UAS operators to contact the controlling agencies directly, while at the same time ensuring that manned aircraft are given the proper separation from UAS.
The team acknowledges that FAA ATC facilities are understaffed and overworked. JUATT proposes that with Flight Service Station hub facilities currently housing experienced air traffic control specialists already familiar with unmanned operations, a mere software upgrade to the FS21 system could allow commercial unmanned aircraft operations to be safely integrated and separated in the National Airspace System.
"The JUATT method combined with the Flight Service concept would essentially solve all problems the FAA faces with respect to integrating commercial unmanned aircraft into the National Airspace System," added Perry. "Instead of trying to 're-invent the wheel,' perhaps we should be looking at ways to economically and feasibly transform it into what the users need today."
The JUATT team will present their research on Nov. 7 at the Arizona UAS Summit & Expo in Mesa, Ariz.
