URClearED a Unified Integrated Remain well Clear concept in airspacE D-G classes

Obiettivo

There is a general consensus among experts in the field of air transport that we will see a growth in the use of certified remotely piloted aircraft systems (RPAS) for civil and commercial purposes.

Safety of these operations will be critical. That is why the URClearED project addresses the 'remain-well-clear' (RWC) function, one of the key technological issues that will allow certified RPAS to safely share airspace with other (manned and unmanned) aircraft at intermediate altitudes. Here we are referring to altitudes below 18,000 feet, well below typical cruise altitudes of commercial airliners which fly at around 40,000 feet. Down there the air traffic is prevalently constituted by small and medium-sized aircraft, like helicopters, General Aviation and even smaller vehicles.

RWC is a 'preventive' function in the sense that its aim is to identify well in advance situations in which two aircrafts would fly too close to each other. Therefore, remaining well-clear is a critical function for keeping a safe distance from other aircraft, avoiding that such situations could become a hazardous mid-air collision.

URClearED aims to define the requirements and capabilities for the RWC function, to be integrated in RPAS vehicles flying IFR into specific parts of the sky that are referred to as airspace classes D-G. These air segments are indeed the most challenging portions of the airspace for the design of such a function for two main reasons:

  • In most parts of airspace (D to G), air traffic controllers provide separation, which means the RWC is considered only as a backup function (for example, in class D with IFR traffic). However, in the case of class G, separation is not provided by the controllers, so the remote pilot must rely on the capabilities of the RPAS, hence the inbuilt RWC function.

  • D to G airspace refers to low altitude portions of the sky, below 18,000 feet, in which small and medium-sized aircraft typically fly. Since these aircraft are possibly not equipped with transponders of any kind, they are only visible to the RPAS through active traffic sensors like radar, which in turn are limited in their range and field of view.


Attività nel progetto CIRA

CIRA coordinates the project and is responsible for the development of the RWC prototype which will implement the requirements derived from EUROCAE-OSED and other relevant documents.

In addition, CIRA will plan and execute within the ISF (Integrated Simulation Facility) real time pilot and controller in the loop validation test of the RWC prototype integrated within a certified fixed wing UAS model.

Furthermore, being also a partner/LTP in other research projects that address similar issues, funded by both SESAR JU, namely INVIRCAT, PJ13-Sol117, and EU, such as EUDAAS, CIRA is exploiting its participation in URClearED to become accredited as an entity capable of proposing innovative technical solutions, specifically for DAA and ATOL systems, to support the full integration of RPAS in the civil airspace that cover almost all the operational conditions. In particular CIRA, as URClearED project coordinator, represents the project within a coordination team of all the running projects belonging to the Advances Air Traffic Services of the SESAR 2020, dealing with the issue of RPAS integration.

Finally, CIRA, as project coordinator, will strongly contribute in collecting results and in deriving recommendations for future more higher TRL activities.
