URClearED (A Unified Integrated Remain Well Clear Concept in Airspace D-G Class)

In aviation, "Well Clear" refers to a state in which a pilot considers the situation of the aircraft to be safe in relation to the surrounding traffic. The SESAR project URClearED is concerned with a formally precise definition of a Well Clear concept in airspaces D to G, particularly involving drones. Automatic systems that can determine the "well-clear state" of a drone are still the subject of research.

URClearED aims to support ongoing study activities by defining and analysing functionalities and operational scenarios for drones, and evaluating requirements and assumptions in order to incorporate them into current standards. This paves the way for future activities with such unmanned systems on an industrial level.

In URClearED, the Institute of Flight Guidance is primarily responsible for the simulation activities. It coordinates the activities for the definition of the test plan, identifies test facilities, plans the integration and conducts test campaigns. Furthermore, results are analysed and performance parameters are derived from them. The Institute is also involved in the definition and implementation of RWC (Remain Well Clear) requirements in the application tool and in the definition of deployment scenarios. The Institute's expertise gained from previous projects and its participation in international working groups and standardisation committees helps in this process.

This project has received funding from the SESAR Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 892440.
