Abstract. In the International Civil Aviation Organization, an important area is the development of new approaches to constructing and maintaining effective aircraft flight paths. Developing a flight control system capable of not only stabilizing the position, but also accurately tracking the trajectory for an aircraft is a rather complex task. In this paper, an algorithm for generating trajectory tracking control is proposed based on the methods of optimal control theory (OCT) using optimal filtering theory (OFT) approaches to estimate the trajectory motion parameters. The formulation of an autonomous optimal control problem is considered. In the paper, the flight route maintenance quality indicator is formulated as minimizing the deviation of the actual flight path from the specified one. The expediency of implementing the proposed approach is confirmed by the methods of simulation statistical modeling. To test the validity of the proposed approach, a simulation modeling of a typical flight path tracking under expected operating conditions was performed. Analysis of the results obtained during the simulation modeling shows that the deviation of the controlled flight path parameters from the specified values does not exceed 5 m. The results demonstrate the efficiency of the algorithm for tracking a specified flight path and its stability to external disturbances.

Keywords: aircraft, flight path, Kalman filter, optimal control, optimal filtering, global navigation satellite system, trajectory control system.

Abstract. The article considers the urgent task of optimizing the use of the existing and promising fleet of aircraft of domestic production within the framework of the creation of a single Far Eastern airline. The data on the assessment of the required number of aircraft of domestic production through a single consolidated order from all airlines of the Far Eastern region analyzed. It is shown that mathematical modeling and optimization methods play a significant role in the optimal design of the number and nomenclature of aircraft in the region, which are successfully used to select the best parameters and characteristics of aircraft or its subsystems at various stages of design, dividing the task into two interrelated models: parametric and operational. A systematic scientific and methodological approach to the external design of aircraft proposed, so it is possible to generate many design options for aircraft, limiting only those parameters that significantly affect the efficiency of the airline’s operation. The result of the study is the fulfillment of the task of optimizing the aircraft model range for subsequent operation in the conditions of the Far North, the Arctic, Siberia and the Far East. The analytical materials obtained allow us to compare the expansion plan of the route air transport network and the calendar plan for the production of aviation equipment for the united Far Eastern airline based on the produced relationship chart between airlines and aircraft manufacturers.

Keywords: mathematical modeling methods, unified Far Eastern airline, model range optimization, unified consolidated order.

Annotation. The article provides statistical data on passenger turnover of air transport in comparison with other types of transport in Russia, as well as flight safety indicators over the last decade. The leading types of events leading to aviation accidents have been identified. It has been revealed that the cause of many of the negative aviation events that have occurred are violations of the functional state, loss of performance and errors of crew members, which are facilitated by the conditions of the person’s environment.

The authors study the variability of heart rhythms, reflecting changes in the psycho-emotional state of a person during noise. The results of the study confirm that a change in the activity of the sympathetic and parasympathetic parts of the autonomic nervous system of the human operator. This indicates the development of stress under the influence of noise.

The authors demonstrate the importance of counteracting the negative effects of noise on aviation personnel to improve flight safety and reduce injuries and propose to use otoprotection with an oxygen-argon gas mixture to concentrate the attention of the crew in extreme situations.

Key words: air transport, aviation accidents, human factor, noise, otoprotection, argon.

Abstract. Individual non-formal online language learning format is becoming more popular around the world. However, it is observed that the theoretical and methodological foundations are currently not fully developed. The article considers the advantages of non-formal individual online teaching Russian as a foreign language to adult learners under the teacher’s guidance, as well as a set of organizational patterns, approaches, and principles of functioning of this educational phenomenon. We have found out that individual non-formal online language learning is based on the following pedagogical organizational patterns: the management of the pedagogical process, the unity of teacher and learner’s activities, the dynamics of the pedagogical process. Effective organization of learning process is one of the current problems of modern didactics; therefore, it is important to consider the theoretical and methodological justifications of popular educational trends.

Keywords: non-formal online language learning, Russian as a foreign language, online format, methodological justification, synchronous online learning, synchronous and asynchronous modes of communication, online teacher.

Abstract. The article examines the fatigue of flight personnel and members of the air traffic control service as a risk factor affecting flight safety. The proposed software solution based on the random forest method makes it possible to identify the state of fatigue in an aviation specialist after passing a series of tests evaluating a decrease in performance based on existing symptomatic attributes. The introduction of the presented solution into flight safety management systems at aviation enterprises will improve the corresponding reliability indicators of both pilots and air traffic controllers.

Key words: fatigue, assessment, statistics, machine learning, binary classification, random forest, automation, program.

Ekaterina O. Tumanova

Abstract. Historical, cultural, political, economic and sporting events that are significant for a particular linguistic-cultural community are fixed in the linguistic consciousness of native speakers and are reflected in their lexical composition. The article is devoted to the description of semantic and stylistic peculiarities of German eonyms, i.e. lexical units whose semantics include allusions to the events in various spheres of life that gave rise to them. The research material is represented by “epithets of the year”, i.e. adjective names from the rating lists of the annual linguistic campaign of the German Language Society in Germany “Word of the Year” for the period from 1971 to 2023. The author has devoted his study to the description of the main characteristics of the selected units. The special stylistic features of eonyms-adjectives testify to their metaphorical character and the possibility of fulfilling the stylistic function of epithets. The article gives a general characterisation of eonyms-epithets in their diachronic aspect. The approach proposed by the author to the study of the linguistic reflection of historical events in German-language discourse is of interest to specialists in the field of linguistic-cultural studies.

Keywords: eonym, adjective, epithet, linguistic reflection, word of the year, the German language, key words of the current moment, linguistic-cultural studies.
