Florida NextGen Test Bed UAS Project Uses Conflict-Probe Software

Adacel, a provider of air traffic automation, says it recently participated in a trajectory-based operation (TBO) and unmanned aircraft systems (UAS) integration demonstration project at the Florida NextGen Test Bed at Embry-Riddle Aeronautical University in Daytona.

According to Adacel, the project, sponsored by the Federal Aviation Administration, serves to further mature TBO concepts through research and development efforts aimed at identifying the functional capabilities for integrating four-dimensional trajectory operations in the National Airspace System (NAS). This was done so by using UAS as a platform within Class A airspace.

One of the objectives of this segment of the project was to investigate trajectory negotiation processes/concepts to resolve conflicts by focusing on the en-route phase of flight. Working as part of a team of industry partners, Adacel adapted its Aurora conflict-detection software – which uses communications, navigation and surveillance/air traffic management technology – to work in a flight information exchange model (FIXM) environment. FIXM is a data interchange format for sharing flight information.

Adacel says its Aurora technology is currently in operational use in airspaces controlled by Fiji, France, Iceland, New Zealand, Norway, Portugal and the U.S.

The outcome of the project will include recommendations on updates to concepts, standards and benefits of the future integration of UAS into the NAS. The recommendations can then be provided to key stakeholders, explains Adacel.
