Limited Delegation of Separation Assurance to Aircraft: The Freer Flight Evolutionary Air Ground Cooperative ATM Concepts

Air traffic management (ATM) concepts of the future are committed towards significantly enhancing the capacity and making flying even safer. Since, these new ATM concepts will change the roles and responsibilities of pilots and the air traffic controllers, it is important that their impact on safety be evaluated. Many proposed schemes includes shifting the separation assurance function (maintaining safe distances between aircraft) to the cockpit from ground based air traffic control, and to assign a supervisory role to the air traffic controller, who would make decisions in exceptional cases. Some initial research in this direction has shown that controllers cannot intervene effectively without decision support tools like "conflict probes". Furthermore controllers and pilots have different strategies for resolving conflicts about separation and airspace. Accordingly, there is a need to better understand and classify the decision-making behavior of different agents in the future proposed ATM system. This paper presents a theoretical discussion outlining the application of the Lens Model of Brunswik to provide insight into some of the research questions posed in conflict detection and resolution by future ATM concepts. We illustrate the approach through an example case study.

The current concept of air traffic control based on human work was created many years ago and is now approaching the limit of its performance. Therefore, new concepts for air traffic control are being sought. One of the ideas is to delegate the responsibility for ensuring separation between aircraft to aircraft crews. The issue of self-separation is quite a difficult task. Analysis of the literature concludes that the transition from one phase to another will occur in stages. This paper focuses on the transition period. The concept of a method of ensuring separation when changing traffic organization was proposed. A vital element of the separation method in the transition period is to define the negotiation and communication process between aircraft, which was presented in this paper.
