“…Korn et al [3] and Pütz et al [4] reported on first proof-of-concept simulations. Further simulations were run to investigate different aspects of the concept; Biella et al [5] covered operational feasibility, while Birkmeier et al [6] explored the compatibility with SESAR (Single European Sky ATM Research), priority rules and avoidance maneuvers [7], mental models [8] and controller tasks [9].…”

Today air traffic management divides the airspace into sectors. Controllers are responsible for one of these sectors and all the air traffic within. In a sectorless air traffic management concept the airspace is no longer divided into sectors but regarded as one piece. Controllers are assigned individual aircraft which they are responsible for from their entry into the airspace to their exit. This implies that the controllers have to manage flights which are not in the same geographic region but can be anywhere in the airspace and hence also in different traffic situations. Such a change of concept influences the way controllers work and calls for different support tools. Naturally, the question of safety arises with regard to standard operations as well as special situations. This discussion paper investigates the different safety aspects relevant in a sectorless concept. It highlights the differences between a conventional sectored and the proposed sectorless approach. We argue that most elements of the current safety net in air traffic management can also be applied to a sectorless air traffic management concept. Additional safety net elements are proposed together with examples of their application.

In sectorless air traffic management the airspace is considered as one piece instead of partitioning it into sectors. The air traffic controllers are no longer in charge of sectors but are given responsibility for a certain number of aircraft during their entire flight. This entails that the controller has to keep track of several different traffic situations geographically spread out over a potentially large area. Of course, such a considerable change of concept has implications on the controllers' mental model and the way conflicts are solved. This paper describes the shift of the controller's mental model away from one geographically limited view with long-term planning to several global views with short-term planning. It is illustrated how this altered mental model also implies changes of the controller's tasks and conflict solving. Real-time simulations within DLR's LRM2020 project have shown that working with a sectorless concept is possible and feasible if the co ntroller is supported by suitable conflict detection. The details and results of these simulations are given and the effects of the altered mental model are analyzed. It is furthermore explained how a sectorless concept could change controller work away from controller teams consisting of executive and planner to a one-person workplace supported by a conflict detection. At the same time the principle that two pairs of eyes are better than one is retained. The controller's tasks are not reduced to monitoring jobs but the essential conflict avoidance task remains

“…According to a prevailing opinion, this trend is unlikely to change in the future, although a number of contextual factors, such as political climate, economy, environmental issues, safety issues and security issues may affect its actual rate. Further, according to the 'Free Flight' and the '4D Trajectory Management' concepts, different types of aircraft, such as manned, unmanned, and autonomous aircraft, as well as all kinds of rotorcrafts, will operate simultaneously in a 'structure-less' and 'time based' environment [1][2] allowing for much more direct and continuous trajectories to be used. Also, brand new airspace designs, possibly dynamic, may be required.…”
