Анотація: Purpose: As air traffic of European air space tends to gradually increase, already applied measures for traffic estimation and capacity optimization recede into the background. Accordingly, the aim of this study is to investigate methods, means, methodology and models of European airspace capacity forecasting and provision being used on today’s basis or planned to be used in short-run perspective. Another objective is to prove that air traffic and capacity maximization measures shall be one of the primary considerations during air traffic flow and capacity management activities. Methods: Generalization of pertinent information about existing types of air traffic and capacity forecasts. Theoretical analysis of appropriate literature and Internet resources with the aim of identification of methods, models and other ways of European airspace capacity optimization. Allocation of three major groups of tools directed on air traffic flow and capacity prediction and maximization. Result: Formalization and representation of simplified scheme of main stages of air traffic and capacity forecast creation as well as classification of tools used for traffic and capacity estimation were proposed. An overview of components of above mentioned classification and statistics on the rate of traffic flow and capacity in Ukrainian airspace for the year of 2016 were given. Discussion: The need and approach for air traffic and capacity forecast creation, informational tools, methodology and modeling tools used for capacity enhancement, necessity for air navigation service providers to consider foresaid as a powerful way not only to improve capacity and air traffic flows but also follow Eurocontrol recommendations.
