DYNAMIC DISCIPLINE OF PARALLEL SERVICE IN CONCEPT FLIGHT AND FLOW – INFORMATION FOR A COLLABORATIVE ENVIRONMENT

Abstract

The International Civil Aviation Organization (ICAO) has published documents regulating the measures aimed to increase the intensity of flights. It is supposed to introduce qualitatively new principles of air traffic management based on the technical achievements in the field of communication, navigation and surveillance. The existing dispatching service technology is based on the principle of regulating the flow of aircraft through the feedback mechanism. The plan of the airspace utilization is used as the model for the management process. Deviations in the measurand of the aircraft movement from the calculated values can create prerequisites for potentially conflict situations and require the intervention of air traffic controller. The adjustment tool is a new distribution of the aircraft in their place, time and height. Following the instructions of the dispatcher, the pilot either proceeds to the bypass route, or changes either the altitude or speed. Minimal interference in the actions of the pilot is one of the criteria for assessing the controller’s work. The essence of ICAO's proposals is in the transition from the "tracking" system which responds to the deviations from the balanced model to the control system which predicts the tendencies to changing the air situation in real time. In order to realize this intention, every ground center and every crew should have consistent information about the real situation in the air and its development, so that each new intention (decision) is modeled, agreed on by the colleagues and fixed in flight plans. To reach the success in co-regulation of the situation it is important to have computer support in the field of aeronautical maintenance of decision-making, as well as high-speed algorithms for assessing the current parameters of the air traffic servicing process, such as handling capacity of aerodromes and terminals related to the changes being prepared. The article discusses the dynamic model of collective formation and flow maintenance using system-wide information. The model is built as a multi-channel system with priorities. Analytical estimates of the throughput are given. Criteria for the assessment are the indicators of the probability of failure and the average waiting time for maintenance by controller (refuses include the direction of the aircraft to the alternate aerodrome, repeated circle of landing, delayed departure, etc.). The proposed formulae are confirmed by the results of simulation computer experiments and statistical modeling.
