Abstract. Summary data on injuries in Russia and at civil aviation enterprises over the years of the current century are presented. Continuous reduction in injury rates has been shown. Significant actual factors of the working environment that contribute to occupational injuries have been statistically identified, one of the main ones being noisy workplaces. Exposure to noise has a negative impact on hearing and the functional state of the central nervous system thus reducing performance, leading to errors, and contributing to injuries. The possibility to counter the noise effects by otoprotection with an argon-oxygen gas mixture has been experimentally confirmed.

Keywords: injuries, noisy workplaces, human factor, civil aviation enterprises, otoprotection, argon.

Abstract. The present paper delves into the challenge of implementing international flight safety standards into the Russian regulatory framework governing the establishment, application, and refinement of aviation safety management systems (SMS) in the civil aviation sector in Russia. It underscores the reliance of SMS regulatory adherence on the Standards and Recommended Practices (SARPs) set forth by the International Civil Aviation Organization (ICAO). The paper conducts an examination of prevailing discrepancies, indeterminacies, and ambiguities in delineating core terms and concepts within the English and Russian renditions of ICAO SARPs documentation. Furthermore, it offers an evaluation of the implementation hurdles associated with SARPs in regulatory documentation pertaining to civil aviation flight safety in Russia. The deficiencies in the regulatory infrastructure for flight safety in Russia are substantiated. Drawing from practical insights gained in formulating and improving regulatory and methodological support for SMS in prominent Russian airlines, the paper proposes measures to mitigate inaccuracies and uncertainties in the integration of ICAO SARPs editions within the Russian regulatory framework for aviation industry service providers.

Keywords: international standards, regulatory support, implementation, methodological support, aviation safety, risk, factors.

Abstract. The authors propose a method of predicting the probability of occurrence of dangerous gusts of wind in the runway area during landing of an aircraft, based on the use of the distribution of absolute maximum wind gusts during the observation period. The method makes it possible to design an aircraft landing system that allows, depending on the probability of wind gusts, to make various management decisions: permission to land, sending the aircraft on a go-around, or sending it to an alternate airfield.

Keywords: gusts of wind, probabilistic description, flight safety, aircraft, theory of emissions of random processes, recording device on a probing beam.

Abstract. The accuracy of aircraft position measurements directly affects flight safety and is one of the most important tactical characteristics. The introduction of new advanced surveillance tools, such as multi-position surveillance systems (MPSS), can significantly increase the level of flight safety, as well as improve the efficiency of airspace use. The authors consider the task of improving the quality of MPSS functioning and increasing the accuracy of estimating the aircraft coordinates. The accuracy of position-fixing is determined by the error in measuring the time of signal arrival under the influence of noise and interference. Random disturbances must be taken into account to ensure high-quality MPSS operation. This is achieved by applying the methods of Kalman filtration theory. Therefore, to solve the problem of estimating the MPSS state variables, it is proposed to use a Kalman filter (KF). The effectiveness of using the Kalman filter depends on the adequacy of mathematical models and real processes. Model inaccuracies associated with the functioning of navigation systems lead to KF divergence. The paper presents the results of theoretical studies and simulating the MPSS functioning processes based on the implementation of the KF algorithm.

Keywords: Kalman filter, divergence of the filtering process, estimation algorithm, multi-position surveillance system, random disturbances, aircraft.

Abstract. In the first part of the article, the author proposed a modified method for confirming the ADS-B data, which estimates and compares the aircraft flight altitude: barometric altitude (received from a barometric pressure altimeter) and geometric altitude (received from a GNSS receiver). In the presented work, application of the modified technique for confirming the ADS-B geometric altitude data is simulated. When simulating, real data were used which were received from the ADS-B ground station located at the Mezen aerodrome. Real values of pressure and temperature were used. The methodology takes into account the values of quality indicators of ADS-B data. For one flight on local airlines, an excess of the permissible interval was shown (GNSS data, according to the methodology, are not confirmed). The result obtained is consistent with the geometric vertical accuracy parameter GVA. To verify the modified method of the temperature determination according to geometric and barometric altitude, the obtained temperature data are compared with the values of the ECMWF forecasting model. The average RMSE value for 11 flights was 1.58ºС. For climbing aircraft the maximum RMSE value was 1.93ºС, for landing aircraft, maximum RMSE = 2.7°C.

Key words: flight safety, ADS-B, model, local airlines, barometric altitude, geometric altitude, TAS, IAS.

Abstract. The paper provides an overview of the components of the pilot model used to design the flight control system which focuses on the physiological aspects and aspects of manual control. The structure of a multi-element system is used which allows the authors to reveal the totality of interaction between the pilot and the aircraft during the implementation of manual control. Manual control is the most difficult process when performing an aircraft flight and requires a lot of experience and high pilot skills. The sensory and intersensory models of the pilot–aircraft system are considered. The application of these models requires knowledge of the mechanisms and processes that are directly involved in the development of the pilot’s spatial orientation when controlling the aircraft manually. The development of a method and a mathematical model for the formation of spatial orientation skills is an urgent task of scientific research.

Keywords: pilot, model, spatial disorientation, aircraft, sensory organs, human factor.

Abstract. The results of an analysis of the influence of pilot age on injury statistics in civil aviation are described. The proportion of aviation accidents caused by human actions remains the same and even tends to increase. Workers continue to get injured during ground handling operations for aircraft. The authors’ assessment of the various risk factors contribution to ongoing negative events confirms the human factor prevalence. Statistics on the activities of civil aviation was analyzed. Examples of aviation accidents involving general aviation aircraft and medical aircraft transporting patients who required emergency medical care were considered.

It has been shown that there is a peak in the aviation accidents for pilots aged 50-59 years, and this peak is observed among experienced pilots with more than 5,000 hours of flight time. For pilots aged 40-49 years, half of the accidents occurred among aircraft commanders with 1,000 … 5,000 hours of flight time, and about one third among pilots with less than 500 hours of flight time.

It was revealed that for domestic general aviation in 2020, the main causes of aviation accidents were such elements of human factor as piloting errors associated with deficiencies in training and little flight experience; loss of spatial orientation in weather conditions that do not comply with visual flight rules, when the underlying surface is white, when caught in a snow whirlwind, as well as a collision with power line wires.

Keywords: aviation, flight safety, industrial safety, human factor, pilot age.

Concerning the aberration law application in radio navigation and aircraft surveillance

Abstract. The author analyzes the potential use of the aberration law which describes the deviation of measured parameters of an observed object as it changes its position relative to the observer. The law was studied in terms of its application in radio navigation and aircraft surveillance. During research the author obtained dependences of deviations of observable and real (true) characteristics of an observed object for such aids of radio-technical support of flights as a primary radar, distance measuring equipment (DME) and a ground station of automatic dependent surveillance. In doing so, the speed of the observed object was set equal to 250 m/s (typical for existing airplanes) and 600 m/s (specific for perspective supersonic airplanes). It follows from the calculations that the aberration effect cannot be detected for determining slant range or pulse duration tasks due to the imperfection of the existing measuring instruments. However, the aberration effect can be detected in the tasks of determining the time interval between probing pulses of the primary radar or automatic dependent surveillance messages, as well as in the determination of the frequency of the DME signal. This is achieved due to a sufficiently large dynamic range of the measured values. For the method of evaluating the aberration effect given in the paper the author performed estimation of the sensitivity to the errors of the measured value and the velocity of the observed object. The research confirmed possibility to apply the law of aberration in practice for radio navigation aids and aircraft surveillance, which can increase accuracy of position-fixing and determination of aircraft movement parameters as well as to expand capabilities of the available equipment.

 Key words: aberration, true parameters, observed parameters, radio navigation aids, aircraft surveillance aids.
