Current state and prospects for development of systems for planning airspace management. Part 1

In the general air traffic management system, one of the main functions is performed by the airspace planning (ASP) subsystem, which carries out preliminary (strategic), daily (pre-tactical) and current (tactical) planning with the required quality indicators, the values of which depend on the location and tasks of the aerodrome.The paper is the first part of the review of existing airspace planning systems. The purpose of the study is to review and comparatively analyze existing air traffic models. Currently, the following air situation models are known: network, probabilistic, load dynamics, expert, air situation development, potentials, entropy. The paper provides an overview of them, identifying their advantages and disadvantages. These models are used to predict air traffic intensity, calculate the shortest routes, form the order of departures and arrivals of aircraft. However, the increase in requirements for airspace capacity and the need to ensure a high level of air traffic safety, with restrictions on aircraft flight parameters, fuel consumption and other indicators of air traffic service quality creates a problematic situation, which, at present, has not been resolved in the existing airspace planning systems. The use of existing models in high-intensity air traffic leads to a significant increase in average fuel consumption, which is why they need to be improved.
