The aim of this project is to justify the necessity of a specific airspace dedicated to drone operations, in particular in the Urban Air Mobility (UAM) field, and to expose which aspects are going to be the most limiting in the design of this airspace for autonomous aircrafts. The commercial aviation case is presented to demonstrate that an effective implementation of the UAM requires the creation of a dedicated airspace as well as international legal harmonisation: a mode of air transportation that carries out thousands of flights every day while ensuring high levels of safety at all times thanks to its defined rules and airspace structure. The different reasons why the aviation airspace cannot be escalated to the UAM are also exposed. Once the necessity for the UAM sector to have its own drone-designed airspace has been justified, the main barriers and potential solutions that the experts and corresponding authorities working on the sector have identified are exposed. These challenges come from fields as diverse as operational security, infrastructure and ground area protection, adverse weather conditions, technological and vehicle limitations, and a factor that is often overlooked but is crucial: social acceptance. The establishment of the UAM airspace will require the development and design of a ground infrastructure capable of ensuring that aircraft can takeoff and land safely in each operation. The main European vertiport guidelines are explained. To conclude the project and use the knowledge acquired in its elaboration, a use case in the UAM sector is briefly designed: the transport of VIPs by drone from different Catalan airports to the ¿Circuit de Montmeló¿ in punctual cases, such as when a Grand Prix is held.
