In this study, a total of 2,584 domestic research papers with the keywords "Aviation Safety" and "Aviation Accidents" were subjected to Text Mining analysis. Various text mining techniques, including keyword frequency analysis, word correlation analysis, network analysis, and topic modeling, were applied to examine the research trends in the field of aviation safety. The results revealed a significant increase in research using the keyword "Aviation Safety" since 2015, with over 300 papers published annually. Through keyword frequency analysis, it was observed that "Aircraft" was the most frequently mentioned term, followed by "Drones" and "Unmanned Aircraft." Phi coefficients were calculated for words closely related to "Aircraft," "Aviation," "Drones," and "Safety." Furthermore, topic modeling was employed to identify 12 distinct topics in the field of aviation safety and aviation accidents, allowing for an in-depth exploration of research trends.

When landing an aircraft descent-speed, wind around the airport, and regulations are important indicators for the pilot to decide whether to land in the Final Approach. In this study, in order to maintain a decent angle accessible to the airport, the pilot predicts an appropriate decent rate suitable for wind direction, wind speed, and speed to make a stable landing. To confirm this, the decent rate according to the speed and speed of wind was calculated using the information actually measured on the B737NG aircraft and compared with the theoretical figures. The purpose of this study is to ensure that the pilot can make a stable landing at a given FPM (Feet Per Minute) when a visual approach and non-normal approach is required at an airport designed with a somewhat higher descent angle.

The aviation demand forecast field has been actively studied along with the recent growth of the aviation market. In this study, the demand for domestic passenger demand and freight demand was estimated through cross-validation method. As a result, passenger demand is influenced by private consumption growth rate, oil price, and exchange rate. Freight demand is affected by GDP per capita, private consumption growth rate, and oil price. In particular, passenger demand is characterized by temporary external shocks, and freight demand is more affected by economic variables than temporary shocks.

Recently, the issue of maintaining pilot competency has emerged as one of the major challenges in the aviation industry due to irregular schedules and flight intervals caused by the global COVID-19. Therefore, a survey was conducted on airline pilots to determine how stressed they would be when returning to their flights after experiencing irregular schedules or long-term furloughs. The level of stress that pilots receive due to flight intervals was divided into periods, and correlation with general characteristics was identified to see what emotional burdens exist as the lengths of flight interval increased. As a result, burdened flight intervals and the Pilot Flying(PF) intervals were identified as a statistically significant variables. In the case of the Pilot Flying interval, the level of stress was confirmed to be worse as the flying interval was elongated, and in the case of the burdened flying interval, the tendency of the stress index were lower as the period increased. Through this study, pilots who experienced reduced flight times were found to be accompanied by considerable amount of emotional burden proportionate to the length of the interval period.

The purpose of this study was to analyze the effects of Student Majoring in Flight Operation's propensity, safety behavior and aeronautical decision-making. According to the analysis results, First, parents' criticism of perfectionism factor is found to have a negative effect on safety behavior. Second, student pilot's proactive personality has a positive impact on both safety participation behavior and safety compliance behavior. Third, both safety participation behavior and safety compliance behavior are found to have a significant effect on situation awareness, solution generation and solution implementation of decision making stages. Therefore, this study is intended to provide useful basic data that can be applied to studies such as appropriate psychological counseling, optimal training directions and teaching methods in order to cultivate excellent human resources through safe flight training.

Flight instructors at aviation training centers are exposed to various stresses, such as stress caused by special work environments, stress caused by working conditions, and stress related to uncertain future airline employment. These stresses are expected to not only affect flight safety, but also adversely affect the job satisfaction of flight instructors, and consequently negatively affect the performance of high-quality flight education. Therefore, this study was conducted to understand the effects of these stresses on the job satisfaction of flight instructors by examining the stress experienced by flight instructors in flight, psychological, and physical aspects based on the results of previous studies on stress. To the end, this study conducted a survey of flight instructors belonging to aviation training centers, and as a result of analyzing the collected data, it was confirmed that the physical stress of flight instructors had a significant negative effect on their job satisfaction.

An empirical analysis was conducted on the workload of helicopter pilots flying in high-risk flight environments such as ground obstacles and weather effects at low altitudes. To evaluate the workload, an independent sample t-test was performed using the NASA-TLX evaluation method most suitable for the aviation field, and the workload score was calculated by applying the analytical stratification method (AHP) to compare and analyze private and commercial pilots. There is a significant difference in mean between private and commercial pilots and the result of work load was obtained over 70%. This paper studied the 'surprise and startle effect' on the helicopter field for the first time. In the future, it is intended to contribute to the safe operation of helicopters by presenting a method for effective safety management by utilizing it in the field of education and training for helicopter pilots and providing basic data for preventing accidents caused by human error.

The importance of human factors has been emphasized for pilots because most of aviation accidents have been caused by the human factors of pilots. Human factors issues such as fatigue affecting flight safety are needed to be educated to student pilots who have less experience in flight training. In order to prevent aviation accidents caused by human factors, the management of stress, fatigue, and obsessive-compulsive disorder which increase psychological harmful factors of student pilots, is essential for aviation safety. The management of fatigue is required as a part of safety management system following the guidance of leading aviation authorities. The purpose of this article was to investigate the factors of fatigue at each stage by classifying it into before, during, and after flight training to manage the fatigue of students pilots. Then, the factors of relatively high fatigue were analyzed by using the AHP process to provide factors related fatigue affecting pilot training.

This study is a pilot operation roadmap for the introduction of the co-pilot qualification (MPL) system, and the introduction of the MPL system in Korea is a new pilot education and qualification system based on competency. Therefore, it may be difficult to prepare for various matters such as securing initial regulations, securing training businesses or trainees, and establishing training infrastructure, so the roadmap necessary for pilot operation is very important for the successful introduction of the MPL system. In order to secure a training program and qualification system with proven MPL systems in the domestic aviation market, the government and aviation industry members will jointly participate to highlight the importance of a pilot operation roadmap for the domestic flight environment.
