Current state and prospects for development of systems for planning airspace management. Part 1
DOI 10.51955/2312-1327_2025_1_86
Abstract. 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.
Keywords: air situation models, airspace planning, ASP, air traffic safety, fuel consumption, trajectories.

Correlation analysis of technological processes relative to controlled product parameters
DOI 10.51955/2312-1327_2025_1_6
Abstract. The correlation analysis method is not limited to finding the closeness of the relationship between the studied parameters. Sometimes it is supplemented by the compilation of regression equations, which are a description of the correlation relationship between the resulting and factorial features. This approach is called the correlation and regression analysis method.
This article devoted to the study of the processes of manufacturing industrial products shows the expansion of the possibilities and practical applicability of correlation and regression analysis methods to establish the relationship and interdependence of technological process parameters in order to increase quality control of finished products.
Keywords: correlation and regression analysis, quality of finished products, controlled parameters of technological processes.

The analysis of the possibility to use a pyrohydraulic generator in the emergency system of an aircraft landing gear
DOI 10.51955/2312-1327_2025_1_117
Abstract. A number of problematic issues related to the design features and operation of the main and emergency landing gear systems of modern aircraft are considered. Some contradictions have been noted between the necessity to improve reliability and certain difficulties in using additional emergency landing gear systems on military aircraft. As a result of the analysis of various landing gear extension systems, the Yak-130 aircraft was identified as the object of implementation of the authors’ development on the use of a pyrohydraulic generator in the emergency landing gear extension system. The principle of design and operation of the main units of the proposed system is shown. Using the example of the nose landing gear of an aircraft, a schematic diagram of the functioning of the proposed method of extending the landing gear with a pyrohydraulic generator is demonstrated. Based on the results of the study, the feasibility was confirmed and the possibility of using a pyrohydraulic generator in the emergency landing gear system of an aircraft was justified.
Keywords: Landing gear, extension system, pyrohydraulic generator, reliability, flight safety.

Cognitive semantics of the tense-aspect form Present Simple
DOI 10.51955/2312-1327_2025_1_160
Abstract. Despite tireless attention of linguists-theorists and teachers-grammarians to the semantics and functioning of tense-aspect forms in English, theories about the grammar meaning and information in grammar references or textbooks leave much to be desired due to their contradictoriness and weak explanatory clarity. This state of affairs motivates researchers to seek for new, cognitive approaches to studying the semantics of tense-aspect forms. Therefore, the article, on the one hand, provides an overview of traditional interpretations of the Present Simple form available in the research field, and, on the other hand, introduces the reader to a cognitive analysis of the grammar form in question.
Key words: tense-aspect form, grammatical polysemy, prototypical categorization, the Observer, fact.

Unified methodology for planning optimal four-dimensional flight trajectories at the cruising stage in air traffic management
DOI 10.51955/2312-1327_2025_1_22
Abstract. This paper proposes a unified methodology for solving the problems of planning and correcting optimal four-dimensional flight trajectories of an aircraft according to the optimality criteria specified by all participants in the air traffic management (ATM) community, taking into account the influence of wind conditions, no-fly zones, moving zones of difficult weather conditions and other aircrafts. To solve mentioned problems, multilayer neural network models are used to construct user-preferred trajectories based on training the data of completed flights along the corresponding route, the A-star algorithm is used to generate optimal trajectories bypassing stationary and moving zones of dangerous proximity of aircraft, as well as the Bezier curve is used to smooth the piecewise linear trajectories formulated by the A-star algorithm according to the requirements for safe tolerances of aircraft flight trajectories. In order to demonstrate the effectiveness of using the proposed methodology, the authors conducted a series of experiments both when planning optimal trajectories pre-departure and when correcting them in flight, taking into account the presence of danger zones (DZ) in the airspace and without them.
Keywords: optimal four-dimensional flight trajectory planning, optimal four-dimensional flight trajectories correction, multilayer neural network models, A-star algorithm, Bezier curve.

Formation of readiness of specialists of state and municipal administration to use information and communication technologies is a social and pedagogical problem
DOI 10.51955/2312-1327_2025_1_230
Abstract. The article considers readiness to use information and communication technologies in professional activities as a socially significant quality of the personality of state and municipal administration specialists, the formation of which meets the needs of the individual and society. The purpose of the article is to determine approaches to the formation of readiness of state and municipal administration specialists to use information and communication technologies as a socio-pedagogical problem. Readiness of specialists to use information and communication technologies is defined as a stable functional state of the individual, which is manifested in the form of a set of abilities. Contradictions of modern education are revealed, the resolution of which under certain conditions will ensure the formation of specialists’ readiness to use information and communication technologies. Approaches to the study of the formation of specialists’ readiness to use information and communication technologies as a socio-pedagogical problem are determined, which is proposed to be considered in the methodological, scientific, theoretical, methodical and practical aspects.
Key words: readiness to use information and communication technologies, contradictions in higher education.
