As part of the EUREKA SESAR3 Fast Track project, we successfully hosted an Expert Judgement Workshop at Rome Fiumicino Airport, focused on Solution 4: Network Flow, Capacity, and Operational Management. A diverse panel of experts explored how vertiport networks can be effectively integrated with U-space to ensure safe and efficient operations. A key highlight was the introduction of the Vertiport Network Manager—a new stakeholder concept driving coordination across the network.
