In recent years, the widespread use of drones for the transport of people and cargo in and between cities has become increasingly considered. From the point of view of airspace organization, world capitals with high potential for this operation mostly have one common parameter - airspaces defined as controlled zones are established above them, as an integral part of airspace around large international airports. Given the current state of knowledge and the global degree of implementation of unmanned traffic management, it is necessary to solve how to integrate the operation of drones alongside aircraft with crew on board, for which the current rules are defined. On the other hand, the rules for the joint operation of manned and unmanned aircraft, have not yet been sufficiently defined. The aim of this paper is to present the needs for individual solutions for this dedicated part of integration at the European Union member states level and to define the sub-areas that need to be defined and put into operation by regulators and interested institutions. This is achieved through analysis and a specific case study that identifies individual needs and helps to classify them. The combination of identified needs allow the creation of a flowchart showing the logical procedure for the gradual adaptation of Beyond Visual Line of Sight traffic in controlled zones.
