Abstract: This paper presents an enhanced method for detecting critical edges in spatial-temporal route networks based on complex network analysis. Unlike previous models, the proposed approach accounts not only for the topological characteristics of routes but also for their dynamic variability through a composite weight that includes the average travel speed and its variance. Additional metrics, such as load centrality and robustness of connectivity, are introduced. Critical edges are automatically identified via percolation analysis, without the need for manual threshold adjustment. For criticality prediction, a gradient boosting model is employed, using a set of structural and temporal features. The proposed approach ensures more accurate, reproducible, and adaptive identification of vulnerable segments in route networks and can be applied in real time to support air traffic management.

Key words: air transportation, airway network, complex networks theory, spatial-temporal network, critical link detection, network centrality, percolation theory.

Abstract. The paper discusses value dimensions of the linguocultural regulative concept SUSTAINABLE FASHION. The research objective of the paper is to explore the cognitive basis of the evaluative aspect of the concept under consideration. The study of the value potential of the concept SUSTAINABLE FASHION is viewed from the theoretical perspective of axiological linguistics. Of particular concern in the study is the linguoaxiological analysis of the evaluative language units verbalizing aesthetic value, environmental and ethical value, social value, hedonistic value of the concept SUSTAINABLE FASHION in English media discourse. The results obtained suggest that these value dimensions ensure a more responsible approach to fashion, shaping ethical and conscious consumption behavior.

Kew words: concept SUSTAINABLE FASHION, values, evaluation, evaluative statement, linguoaxiological analysis, media discourse.

Abstract. The safety of ground traffic on the airfield movement area is largely determined by the effectiveness of airfield surveillance systems. Currently, radar surveillance systems are used to solve the tasks of monitoring and controlling ground traffic at the airfield. Despite their high technical and tactical characteristics, these systems are subject to the influence of natural and artificial radio interference, which can significantly limit their application for surveillance and traffic control, to the point of making the information unusable. A promising development is a vibroacoustic monitoring system, the functioning of which is based on other physical principles. However, vibroacoustic surveillance systems also have disadvantages, the main of which is the inability to observe a stationary object with the engines turned off. The urgent task is to combine existing and promising surveillance systems into a single integrated system in which the disadvantages of one surveillance system will be compensated by the advantages of another surveillance system. This article discusses the problem of synthesizing algorithms for complex information processing of object movement in the airfield movement area, with the possibility of reconfiguring information channels.

Keywords: integrated processing algorithm, ground movement, airfield movement area, mathematical model, airfield survey radar, surveillance system, multi-position surveillance system, vibroacoustic surveillance system.

Abstract. The article presents the results of developing a method for determining the optimal route for bypassing an aircraft (AC) of a temporally constant (stationary) zone of thunderstorm activity and heavy rainfall. The method is based on finding the shortest path on a graph. It takes into account the geometries of hazardous meteorological phenomena and the minimum safe distances to them. The authors compare strategies based on the use of convex and concave hulls in the formation of thunderstorm bypass zones. The analysis reveals a statistically significant difference in the central tendencies of the corresponding route lengths. It demonstrates that routes using concave hulls are on average 2% shorter, with possible absolute differences in lengths of up to several hundred kilometers. The main practical result of the work is that the proposed method for determining the optimal route to avoid a thunderstorm can be used as a tool to increase the situational awareness of aircraft pilots and optimize crew operations when flying in adverse weather conditions. It allows automatic thunderstorm avoidance using an autopilot and contribute to improved economic efficiency of flights by reducing fuel consumption through the selection of the optimal bypass routes.

Keywords: aviation, flight safety, optimization, thunderstorm avoidance, shortest path on a graph, Dijkstra’s algorithm, minimum envelope.

Annotation. The federal project of the Ministry of Education and Science of Russia «Advanced Engineering Schools», launched in 2022, aims to provide sectors of the economy with qualified personnel to achieve technological independence for the country. Strengthening fundamental training in higher education depends directly on the level of applicants’ knowledge formed at school. There is a decline in students’ interest in engineering and an analysis of school programs in mathematics, mechanics within the framework of physics, and technology revealed inconsistencies in the study of these subjects, which breaks the logical and content lines between theoretical knowledge and practice. The aim is to stimulate schoolchildren’s interest in engineering and technical activity, which will subsequently contribute to the increase of their learning activity in higher education. It is proposed to introduce interdisciplinary project activities for students in grades 7-11 aimed at forming holistic ideas about the world of technology and general engineering culture, mastering scientific knowledge and practical ways of action, developing key mathematical and natural science concepts reflecting the unity of the world and related to fundamental educational objects (concepts, symbols, models). ). A well-designed process of working on engineering projects will contribute to the formation of such skills as building logical and content lines between the sections of mathematics, physics (mechanics) and technology. For first-year university students, it will be a deep understanding of the logic of creating mathematical and physical models of natural processes and technical phenomena.

Key words: education, activity, interdisciplinary integration, mathematical models, project activity.

Abstract. The article presents a theoretical model of the professional development of a transport security employee’s personality who performs screening, additional screening, and secondary screening for the purpose of ensuring transport security. The model reflects three consecutive stages of personal formation in professional activity: professional training, professional adaptation and development, professional implementation and potential decline. Each stage is described through a set of behavioral characteristics formed in the course of performing official duties. The model is based on empirical observation and relies on regulatory requirements and the professional standard. The results make it possible to trace the dynamics of forming and developing professionally important personal qualities and to use the model for the analysis and improvement of the training system for transport security personnel.

Keywords: professional development of personality, transport security, screening officer, professionally important qualities, stages of professional development, participant observation, professional adaptation, personal qualities, model of professional development.

Abstract. Fairy tale is constantly changing during cultural evolution and technological progress adapting to the new realities through embracing many modern discourses. As a result, a new (hybrid) discourse is being formed, characterized by certain style and plot features. In this article, we make an attempt to analyze one of these hybrid discourses: namely fairy tale film discourse. Taking into account that the main representative of the fairy tale film discourse is a screen adaptation of a magical folktale, the analysis is carried out by studying lexical, semantic and stylistic features of its film dialogue (verbal component). The analysis reveals factors that can influence the relationship between the film version of the fairy tale and its literary basis. The preservation of the main conflict, basic values and main characteristics of the classic fairy tale in the film text as well as the creative development of the original are elucidated. Additionally, some ways of creating a comic effect in fairy tale film discourse are highlighted.

Keywords: discourse, discourse analysis, fairy tale film discourse, film text, film dialogue, screen adaptation, German folktales, Grimms’ fairy tales.
