Integrating Unmanned Aerial Systems into Slovenian civil airspace

Until recently, airspace was reserved only for manned aircraft, in which the crew operates the aircraft when the systems supporting autonomous flight or collision avoidance fails. With the availability of modern technologies to a wider audience, Unmanned Aerial Systems have also become a new reality in the airspace, first as toys and later as means for various commercial services.

The European Union has responded to this new challenge both in the regulatory field through the implementation of new European legislation and in the technical and technological field through the U-Space project. Despite considerable progress, there are still many uncertainties about how to safely integrate Unmanned Aerial Systems, especially in autonomous flight mode, into real airspace that is also used by many other incidental users.

This article presents the concept of integrating unmanned aerial systems as envisioned by the U-space project and provides an overview of the progress and situation in Slovenia. Using the Slovenian airspace as an example, analysis and assessment of the risks associated with tactical airborne collision avoidance by unmanned aerial systems, especially when flying in autonomous mode, was performed.
