Abstract. One of the most important ways to improve aviation radio navigation systems is to increase the accuracy of aircraft position-fixing. Among the factors affecting the accuracy of radio navigation systems is the signal-to-noise ratio, the magnitude and dynamics of which are the subject of this work. The assessment of the signal-to-noise ratio will theoretically improve the accuracy of aircraft position-fixing by applying adaptive filtering algorithms. The article presents the results of theoretical studies of the signal-to-noise ratio and the factors influencing its absolute value. An experimental installation for monitoring signals from air navigation support facilities is presented. To assess the changes in the signal-to-noise ratio, the results of recording and studying the signal of the Doppler VHF omnidirectional radio range (DVOR) at Irkutsk International Airport and the daily log of the signal-to-noise ratio for various GNSS satellites are presented.

Key words: spectrum monitoring, radio intelligence, signal analyzing, interference detection, cognitive radio, radio monitoring.

Abstract. The article presents a comprehensive analysis of the formation and institutional development of pedagogical expertise in Russia (1920-2020s) as a key mechanism for assessing and regulating teachers’ professional competencies. The specific features of the formation of domestic expert practices are revealed; their interrelation with the socio-political and technological transformations of Russian society is substantiated; the cyclical nature of the problems of the institute of expertise in education (ideologization, formalization, crisis, standardization) is determined. The various innovative approaches for its improvement are being considered. The potential for the development of tools for measuring the effectiveness of pedagogical practice is shown through a multimodal system for evaluating pedagogical effectiveness; a digital ecosystem of expert communities; personalized professional growth trackers, etc. The materials of the article can be useful in developing new criteria for evaluating teachers, taking into account not only formal indicators (length of service, qualifications), but also pedagogical effectiveness, innovative methods.; to create algorithms to reduce the bureaucratic workload during evaluations; to develop educational programs for experts, including courses in pedagogical analytics, as well as to prevent systemic crises and predict risks. The conclusions of the study emphasize the uniqueness of the Russian experience of pedagogical expertise and the need to develop local solutions that take into account the specifics of the national education system.

Key words: pedagogical expertise, expert practice, teacher’s professional activity, professional effectiveness, assessment mechanisms, teacher evaluation criteria, evaluation system reform.

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. A review of publications and research results in the aviation and aerospace industries indicates a lack of development and recommendations for the use of statistical methods to assess the quality and reliability of pyrotechnic devices that are part of such important systems as propulsion systems, separation systems, structural elements of aircraft and other devices. The article presents a methodological approach to conducting a statistical assessment of the quality of pressed parts, as a result of which manufacturers of complex technical units and components will be given the opportunity to reduce the number of defects and alterations, optimize the production process and increase labor productivity. In addition, the stable quality of components confirmed by the results of statistical analysis will ensure reliable operation of finished products extending their service life.

Keywords: tables of classification of controlled parameters, statistical analysis, quality of pressed parts, reduction of the number of defective pressed parts, plans of statistical acceptance control on a quantitative and alternative basis.

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.
