Development of an Algorithm to Determine the Attention Required by Aircraft Under Control Using Fuzzy Logic

In this paper we discuss an algorithm to determine the level of attention which an aircraft under control requires in a sectorless ATM environment. Data were gathered by means of an experiment in which air traffic controllers from Hungarocontrol were tasked with evaluating scenarios within a sectorless airspace. These controllers were asked how much attention an aircraft under control requires, as well as the influence of the surrounding traffic on it. With this data a set of rules was developed, using the principles of fuzzy logic, which will form the basis of the algorithm. On the basis of this algorithm several tools for the sectorless ATM concept can be developed like a priority list of the aircraft under control, a filtering algorithm for the radar display and a heat map showing expected critical points on the trajectory of an aircraft.
