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.

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.

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.

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.

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.

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.

Abstract. The lexicon related to mining and mineral processing is a special segment of the professional language. Both the mining activity itself, which experiences significant changes in the course of technological progress, and the language reflecting this development are in a state of constant transformation. This article is devoted to the study of the thematic corpus of the German mine hoisting vocabulary, which is a narrow segment of mining terminology, while remaining an integral part of it. The subject of the study are terminological units used in the scientific field of mine hoisting and selected as a result of practical translation activity from specialized technical documentation, technological descriptions and guides. The study aims to investigate thematic groups of the German mine hoisting lexicon by using the lexico-semantic field theory. Such a method of analysis has not been used for the investigated professional lexicon before. Thus, the relevance of the study is determined by the insufficient research of thematic corpus of terms functioning in the lexicon of mine hoisting. The study revealed relevant lexico-semantic groups, determined their place in the field structure and elucidated interrelations of the term system in the language.

Key words: professional language, mine hoisting vocabulary, term, terminology, lexico-semantic groups, lexico-semantic field, German.

Abstract. The paper presents a component model of the existential potential of a teacher’s professional development, implemented in the Educational complex “Point of the Future” (Irkutsk), which is a vivid example of an innovative educational environment that supports the existential nature of teachers’ professional development, where self-development acts as a value guideline for both teachers and students. The features of pedagogical work in an innovative educational organization are revealed: “versatility of activity”, “high uncertainty of conditions” and “redundancy of professional opportunities”. Examples of activities contributing to the disclosure of the existential potential of professional development of teachers in the private educational institution “Point of the Future” are given. The tasks of scientific and methodological support are defined as one of the key conditions for actualizing the existential potential of a teacher. The article will be useful for education professionals and heads of educational institutions.

Keywords: existential potential, existential fulfillment, professional identity, reflective culture, professional development of a teacher, innovative educational complex.

Abstract. The study considers the issue of linguocultural types as recognizable images of individuals whose specific verbal and non-verbal behavioral characteristics and value dimensions significantly impact the culture of a particular society.  The background of the research is the theory of linguocultural types proposed by V.I. Karasik. The paper brings into focus conceptual, figurative features and value dimensions of the professional linguocultural type columnist. Of particular concern in the study is the value component of the linguocultural type columnist. The author claims that the core value of the linguocultural type columnist is based on the conceptual properties ‘personality’, ‘individuality’, ‘character’ of the columnist. The linguistic personality of the columnist is viewed as a bearer of personal views, individual opinions and intellectual qualities. The findings of the study can be applied in courses on cultural linguistics, media discourse and pragmatics.

Key words: linguocultural type, linguistic personality, concept, column, columnist, value characteristics, media discourse.
