To validate the FF2020 solutions and approach, tests will be conducted in 10 demonstrators in collaboration with 5 Living Labs across Europe (Eindhoven, Milan, Tartu, Oulu, Zaragoza). The Living Lab partners will provide high-impact demonstrators, and specify their needs and requirements to ensure compliance with regulations, in terms of non-functional properties, safety, tools and processes. We have defined three stages of development in order to reach our full potential. The three stages are:

• Stage 1: Regulatory, governance and technology R&D as well as technical integration (M3-M12). On the first iteration, we will research, develop and integrate regulatory, governance and technology frameworks based on demonstrators’ concepts and users’ requirements and needs. Within this phase, the focus will be on R&D of the regulatory, governance and technical development to deliver a first integrated MVP (based on test data) in M12 to be validated in Living Labs.
• Stage 2: Experimentation and validation (M13-M24). On the second iteration, we will focus on cross-disciplinary R&D by integrating and validating the MVP results deployed in a test environment (lab and field) in the 5 Living Labs. At this stage, Living Labs will prepare the infrastructure and start piloting the different proposed demonstrators. As a result, we will validate operational procedures and mechanisms for an effective interface with U-Space service providers.
• Stage 3: Regulatory, governance and technology integration propel scalability and sustainability (M25-M33). A third iteration will be done with an updated methodology and technological innovations. As the main outcome, we will provide a TRL6 solution for safe UAM operations in urban environments. We will provide proposals for potential regulatory changes and recommendations as a means of compliance. For this, a close coordination with EASA is pivotal to ensure complementarity and consistency within EASA activities.
