DREAMS (DRone European AIM Study), is one of the several projects financed by SESAR Joint Undertaking to start developing and implementation of U-Space in the early future. The purpose of DREAMS is to define the European UTM Aeronautical Information Management operational concept and the project is focused on solutions for the drone aeronautical information management.
The Project is developing through four main steps:
1. The UTM information and service requirements – gathering needs from all UTM stakeholders and all relevant projects;
2. The UTM Information Management (Preliminary) Safety and Regulatory Assessment – that completes the previous point by taking into account its safety and regulatory compliance aspects;
3. The U-AIM CONOPS – providing a reference model for information exchange in the UTM context;
4. The UTM validation platform – used to exercise the information exchange model coming from the previous point.
Main point of the DREAMS Project is the development of a Safety Risk Assessment allowing to determine a set of performance (transaction time, continuity and availability) and safety requirements (technical mitigations) that have to be considered in the planning of an RPAS operations. Also an assessment of regulatory compliance was carried on, focusing on the definition of requirements for service providers in the U-Space and highlighting possible gaps with existing EU (e.g. Regulation 373/2017, 73/2010) and ICAO regulations.
Differences between traditional ANSP (Air Navigation Service Providers) for manned aviation and U-Space providers are underlined. In some cases, completely new definitions are proposed. It also emerged the necessity to adapt classical aeronautical concepts, such as “meteorological minima” or “safe separation”, to drones specific features.
In any case, to demonstrate compliance of U-Space service providers with new requirements, authorities could be supported by competent third parties (e.g. Qualified entities) in training or auditing processes. This need is even more relevant in the U-Space context where the risk level of most operations is high. The allocation of certification tasks to Qualified Entities also represents a means of reducing the burden on authority.
The task assigned to EuroUSC Italia was to perform a preliminary risk assessment of the scenarios identified in the U-Space context and to verify the regulatory compliance of these scenarios where U-Space services are applied, in particular, regarding technical and service providers’ aspects.
The risk assessment was performed using both SORA (Specific Operations Risk Assessment) methodology and a classical risk-matrix based approach. The latter was needed to complement SORA in the Air-Risk evaluation (in particular the possible interactions of several UAS in the same area) and to perform a failure conditions analysis for the U-Space services.
