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.

Denis A. Evsevichev

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.

Abstract.Β Problematic issues related to the operation of the landing gear system of modern aircraft are considered. Some specific requirements for similar systems used on military aircraft are indicated. A constructive solution is proposed in the form of an original development for the use of the energy of powder gases in the emergency landing gear system using the example of the Yak-130 aircraft. The author carried out an analysis of the additional equipment necessary for the operation of the proposed method of extending the landing gear, as well as its impact on the flight performance of the aircraft related to a possible increase in weight as well as changes in the dimensions of the aircraft. Based on the results of the study, a conclusion was made about the possibility of using powder charges in the emergency system of an aircraft landing gear.

Key words: Landing gear system, powder charge, extension cylinder, reliability, flight safety.

Abstract. Communication between an aircraft and ground services is the main means of organizing air traffic control and providing the safety and regularity of air transportation. In order to maintain the operability of radio communication channels is to perform radio monitoring. This article considers a radio monitoring algorithm. It makes possible to classify amplitude-modulated signals by modulation depth, to show the possibility of detection of overmodulated oscillations and to restore the initial information message with sufficient accuracy for its perception.

Abstract. Air traffic management (ATM) in regional air traffic control centers is determined by the availability of surveillance equipment that uses the radar principle of determining the coordinates of aircraft. The responsibility zones of the airspace are vast territories where the placement of radar surveillance equipment forming a single control field is not economically feasible. The presence of local areas of space with no air traffic surveillance significantly reduces the safety, regularity and efficiency of flights. The introduction of new technologies that require significantly lower economic costs needs an assessment of the possibility to use them in the relevant regional ATM centers. Therefore, an urgent scientific task is to study the possibility of using multi-position surveillance systems (MPSS) as an assessment of the accuracy characteristics and locations of system elements. The obtained research results can be applied when placing MPSS ground stations to achieve high performance indicators of the surveillance system and air traffic management as a whole.

Keywords: multi-position surveillance system, multilateration, receiving station, working area, location.

Abstract. The article considers the method of synthesis of an optimal UAV flight path and an algorithm of the flight control system. The system and algorithm are designed for four-dimensional (4D) trajectory-based operations (TBO) in the context of the CNS/ATM and PBN concepts, which will increase the operational efficiency of the UAV navigation and piloting processes. The paper presents a mathematical model of the control object and algorithms for forming a time-optimal flight path. An assessment of the proposed methodology is also presented by verifying and validating the system software using simulation modeling. The results obtained demonstrate the functional capabilities of the control system to create time-optimal profiles of trajectories that meet operational requirements.

Keywords: unmanned aerial vehicle (UAV), control system, optimal flight path.

Abstract. Assessing the technical condition of glazing elements in the cockpits of operational-tactical aircraft still remains the most important task in ensuring flight safety. To increase the efficiency of operations for non-destructive testing of glazing elements using the speckle structure method of optical radiation, the authors propose to use neural network technologies to automatically identify controlled areas in the cockpit. Artificial intelligence technologies have been used to realise this task. They are based on algorithms of semantic segmentation, classification and detection of monitored areas according to the established markers on the cabin due to the application of convolutional neural network on YOLOv8. The application of machine vision technology have made it possible real-time measurement of the glazing exit from the termination when overpressure has been created inside the cabin. This reduces the time for technical condition assessment by at least 10 times. The use of machine vision technologies have made it possible to measure the value of the glazing outlet from the sealing in real time when creating excessive pressure inside the cabin and thereby reduce the time to assess the technical condition by at least 10 times. The authors have established the reason for the discrepancy between the results of using the speckle-structure method of optical radiation in determining the value of glazing yield from the termination and the “tape” method and developed recommendations to reduce measurement errors.

Keywords: non-destructive testing, optical-electronic systems, speckle, semantic segmentation, convolutional neural network, YOLO, glazing.
