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 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.

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. 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. The article provides an overview of the applicability of statistical methods for assessing the results of production processes in various industries. The authors emphasize the effectiveness of the system approach implemented in the methods of analysis of variance, which contributes to technology improvement and allows the influence of each factor and their interaction to be studied in detail. In addition, the results of the analysis of variance can be integrated into the quality management system, which makes it possible to continuously monitor and adjust production processes, and prevent deviations in the output parameters of various parts. The paper provides an example of applying the analysis of variance in the study of technological processes of pressing the components from various materials in designing, manufacturing and controlling the quality of defense and industrial products.

Keywords: analysis of variance, statistical methods, experiment, technological process.

Abstract. The article proposes a method for automated high-precision assessment of the danger of approaching aircraft in case of violation of established separation standards on a continuous 100-point scale. The technique is a step-by-step search for the maximum hazard of approaching aircraft from the moment of the beginning of the violation of separation intervals to the end of the conflict situation. The main criterion for assessment is the linear functional dependence of the values of the minimum distances between aircraft, weighted in the established separation standards. A 100-point assessment will allow for the comparison and comparison of potential hazard between different facts of violations of separation standards, the severity of the threats and risks to flight safety contained therein.

Using “perceived hazard” as a reference points allows assessing the level of flight safety even in the absence of violations of separation intervals for the selected reporting period. The analysis of the estimates obtained using the methodology will help to take timely preventive measures to eliminate potential threats even before the occurrence of real aviation events.

It is advisable to use this methodology in solving the tasks of automating the assessment of practical skills of air traffic control personnel and creating an automatic flight safety management system.

Keywords: normalized coordinate system, normalized distance, violation of separation intervals, hazard of convergence, methodology for assessing the hazard of convergence.

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.
