Introduction. An essential feature of the professional activity of pilots of civil aviation aircraft is the high intensity of work due to pronounced emotional, intellectual, and sensory loads, unique work modes. The study aims to assess the intensity of work and the prevalence of factors affecting fatigue among civil aviation pilots according to an anonymous online questionnaire. Materials and methods. Experts surveyed 667 members of the flight crews in remote anonymous online questioning. We developed the questionnaires under the criteria for assessing the intensity of work, assessing the risk factors for fatigue development according to the ICAO recommendations, and analyzing the pilot's activity algorithm. The researchers used descriptive statistical methods to analyze the survey data. Results. The working conditions of pilots according to 7 indicators of tension correspond to class 3.2: a high level of intellectual loads (72-100% of pilots), a large number of overlapping time zones (18%), the maximum duration of concentrated observation (70.7%), a high density of signals and messages (29.9%), a significant number of objects of simultaneous observation (18.9%), a high degree of risk to one's own life and responsibility for the safety of others (98%), as well as a rough working day (79%). According to the totality of indicators, the general class of labor intensity corresponds to the highest degree (class 3.3). The factors affecting the fatigue of pilots include rare rest between flights (44.6% of respondents), intermittent sleep (59.9%), not always a full sleep before the night flight shift (85.9%). According to the survey results, the share of pilots who have spontaneous sleep during the flight is 74.3%, and frequently delayed reaction to usual, non - standard, or extreme stimuli and signals is 12.3%. Conclusions. The obtained data of the questionnaire survey confirm the results of psychophysiological studies that have shown that the level of the labor intensity of pilots is "super-intense or extreme." Therefore, considering the prevalence of factors affecting fatigue among the crew members, and based on the understanding of the fundamental problems noted by the pilots, it is necessary to develop measures and management solutions to minimize the risk factors for fatigue development.

Introduction. The analysis of working conditions of pilots of civil aviation aircraft has been carried out according to the data of sanitary and hygienic characteristics (SHC). The non-compliances with hygiene standards for several factors have been established at the same time in all SHC. Materials and methods. The 220 SHC of pilots, who had been examined in the clinic of FSBSI RIOH due to suspicion of occupation disease from 2015 to 2019, conducting flights by plane (49%) and helicopter (51%) were analyzed. The methods of account of acoustic load, hygiene assessment and classification of working conditions, peer review methods, and statistical treatment methods have been used. Results. The working conditions, according to the criteria of the Guide R 2.2.2006-05, are assigned to the following classes: 3.2 - in 26%; 3.3 - in 41%; 3.4 - in 33%. Exceeding the permissible equivalent noise levels was recorded at 92% of workplaces. According to SHC, the exceedances were from 1.2 dB to 34.5 dB (class 3.1-3.4). In assessing the work intensity in 83% of cases from 5 to 11 indicators of class 3.2 were recorded. It has determined class 3.3 of work intensity. The levels of general vibration exceeded hygiene standards in 48% of cases (class 3.1- 3.2), local vibration - in 8% (class 3.1-3.2), microclimate parameters - in 67% (class 3.1-3.2), labour severity - in 22% (class 3.1-3.3), less often there were discrepancies in light (6%) and chemical factor (2%). Conclusion. According to a combination of factors, the overall assessment of working conditions of the pilots of civil aviation aircraft in 74% of cases is assigned to classes 3.3-3.4. However, the disadvantages and errors in filling out the SHC can underestimate the degree of harmfulness of the work. To improve the procedure of establishing the connection between the disease, and the profession it is necessary to amend the legislative framework to obtain objective information about the levels of factors affecting pilots, develop a separate form of SHC of working conditions of pilots, detailed instructions about the rules of filling out SHC.

OBJECTIVE: Analyze the association of work organization and sleep aspects with work ability in regular aviation pilots. METHODS: This is a cross-sectional epidemiological study with 1,234 regular aviation pilots who worked domestic and international flights, affiliated with the Brazilian Association of Civil Aviation Pilots. Data collection employed online questionnaire. We compared proportions using Pearson’s Chi-squared or Fisher’s exact hypothesis tests. Then, we conducted Poisson analysis, with robust variance, to test factors associated with moderate or low work ability. RESULTS: The prevalence of moderate or low work ability was 43.3%. We found that selfperception of insufficient sleep (PR = 1.29; 95%CI 1.06–1.57), increased perception for fatigue (PR = 1.51; 95%CI 1.24–1.84), more than 65 flight hours per month (PR = 1.22; 95%CI 1.01–1.46), less than 10 days of time off per month (PR = 1.27; 95%CI 1.04–1.55), and frequent operational delays (PR = 1.23; 95%CI 1.02–1.48) were factors associated with moderate or low work ability. CONCLUSIONS: Work organization was a determining factor for decreased work ability, especially concerning aspects related to rest and its influence on the sleep of pilots.

Introduction. Performing flights on modern types of aircraft is accompanied by an increase in the role of process automation, changes in the structure of the pilot’s information field, an increase in the number of controlled indicators throughout the flight time and, as a result, an increase in sensory loads that contribute to the development of chronic depletion of functional reserves of the body and fatigue of the pilot, which can cause accidents and plane crashes.The aim of the study is to assess the sensory loads of members of flight crews of civil aviation aircraft when they perform regular operating procedures in a Training center on fully functional complex simulators for training cadets, flight, dispatcher and technical personnel of civil aviation.Materials and methods. A hygienic study was conducted to assess the sensory loads of pilots in the framework of performing simulation flights on full-featured complex simulators in strict step-by-step accordance with the manual for flight operation of the aircraft (33 flights were performed with the participation of 66 pilots aged 30–55 years).Results. The data obtained indicate high levels of sensory loads in pilots, which are 9.5 times higher than the maximum values set by the Management of R 2.2.2006–05 and MI NTP. INT–17.01–2018. For 4 of the 6 evaluated indicators, sensory loads corresponded to class 3.2.Conclusions. The general assessment of the labor intensity class for members of flight crews of civil aviation aircraft on the set of sensory loads corresponds to harmful strenuous work of the 3rd degree (4 indicators of sensory loads with class 3.2). The results of the study are the basis for the approval of new hygienic criteria for establishing a class of working conditions for certain indicators of sensory loads for members of flight crews of the aircraft of the civil aviation (CA) with the addition of their class 3.3. A real assessment of the pilot’s labor intensity should be obtained only on the basis of time-based measurements performed as part of a step-by-step analysis of the aircraft’s flight operation manual.

Background: Analysis of aviation accident investigations indicates that one of the main causes of accidents is a decrease in the level of stress resistance of the crew during extreme flight situations, which in turn can lead to a crash. The study of the problem of the negative impact of stressors on the effective operation of the flight crew, indicates that there is a need to form stress resistance in future pilots of civil aviation in the training process. This quality will reduce the threat to flight safety due to human error. Purpose: To characterize publications that actualize the issues of professional stressors in the activities of civil aviation pilots, because their activities are constantly accompanied by many specific stressors, most of which are long-term. Materials and Methods: In the process of research general scientific methods were used – abstract-logical, theoretical generalization, comparison, analysis and synthesis, system analysis. Results: The problem of the impact of stress on the professional activities of pilots is considered, which in modern conditions becomes especially relevant, because the number of air traffic is growing every year. The main four types of general stress that occur in professional flying, as well as the consequences it leads to, are analyzed. Groups of stressors acting on pilots during professional activity are considered and analyzed. An explanation of the psychological mechanisms (aggression, irritability, dogmatism and frustration) that may be involved in trying to cope with a stressful situation. Conclusions: The practical importance for further research in improving the training of future pilots of civil aviation to reduce the impact of the human factor on flight safety was substantiated, as evidenced by the direct impact of stressors on flight safety and the number of extreme flight situations.

Abstract Trying to forecast the human behavior involves acts and knowledge of motivational theories, applicable to profile of each organization and in particular to each individual’s style. The anticipation of personal attitudes has not the only aim for a passive monitoring of professional activity, but also wants to increase performance of risk avoidance, in acordance with a specific organizational environment. The emergence and development of motivational forms and values, whose projections determine social crimes, are risk factors, affecting the professional activity of the person, but also affecting the performance and stability of the institution. Moreover, if the motivation determines attitudes aimed at compromising classified information, the resulting actions may be considered as threats to national security. The prevention of such threats can only be achieved by understanding motivational mechanisms and external conditions for the perssonel that make it possible to transform some intentions into real actions.

Distance learning (DL) changed the work-rest balance of teachers, increased risks of deterioration of their health and emotional burnout (EB). This study aimed to investigate the prevalence of risk factors affecting health and emotional state of teachers engaged in DL, as well as subjective assessment of the significance of these factors by teachers. We have surveyed teachers during traditional, in-person learning (TL) period (n = 224) and DL (n = 619), and took anthropometric measurements of 45 teachers during TL and 72 teachers when DL ended. EB was studied in 72 teachers with the help of V.V. Boyko questionnaire. Statistical processing was enabled by the Statistica 13 PL package, Student's t-test, χ2 test; to identify the relationship between indicators, we relied on regression analysis, effect occurrence probability calculation. Less than half of teachers are aware of the health risk factors (low level of physical activity — 36.1%, poor nutrition — 29.2%, lack of knowledge on disease prevention — 6.9%). After DL ended, only 30% of teachers considered themselves healthy; 13.1% reported lack of EB symptoms. An increase in the average body mass index value was established. Teachers underestimating EB and health risk factors were 2.3 times more likely to grow obese (OR = 0.40; 95% CI = 0.22–0.70). The study highlights high hygienic value of physical activity as a controllable health risk factor. Raising teachers' awareness of health preservation practices will help prevent deterioration of their health, development of EB and increase the efficiency of their professional activity.
