Objectives

To prevent conflict situations in the air, remain-well-clear (RWC) determines the appropriate distance between aircraft. It is a key safety feature in aviation.

The EU-funded URClearED project will build on current research into a detect-and-avoid (DAA) system like that of the RWC. It will define and analyse operational scenarios that are suitable for integration of an IFR RPAS into Class D-G airspace by considering current requirements and assumptions as defined in the EUROCAE OSED.

The project will advance a full RWC functionality of a DAA system that supports estimation for the operational conditions, defining scenarios for verification operations and implementing fast-time simulation and real-time simulation-human in the loop, which permits the analysis of such scenarios and the assessment of performance and safety requirements.

In short, the project aims to support current study activities on the RWC functionalities by defining and analysing operational scenarios which allow to assess requirements and assumptions made in current standards and applicable documents, and then paving the way to future industrial level activities on such system.
the above overall objective will be pursued through:

• define a set of operational scenarios which are peculiar to integration of remotely-piloted aircraft (IFR RPAS) into Class D-G airspace, by taking into account current assumptions and requirements as defined in the EUROCAE-OSED [REF-1] (but also draft OPA, OSA, MASPS under development), also analysing input from all other relevant focus groups and projects;
• develop a full remain well clear (RWC) functionality of a DAA system, which supports evaluation for the operational conditions in integrating RPAS in Class D-G airspace;
• define a set of scenarios for verification activities;
• carry out both fast-time simulation and real-time simulation-human in the loop (both remote pilots and air traffic control officers) which allow to analyze such scenarios and provide validation and possible enhancements/amendments to EUROCAE OSED, as long as performance, safety (including human factors) and interoperability requirements;
• assess Surveillance Sensors performance requirements;
• Integrate the most advanced CA system available, as developed in relevant European projects (MIDCAS, MIDCAS SSP, SESAR PJ10-05 Wave 1, SESAR Solutions 111 & 117 Wave 2) for the full evaluation of the DAA system.
• Dissemination to the relevant stakeholder groups, including participation to standardisation activities.
