This study analyzed the effect of flight stress on job satisfaction and safety culture on 193 domestic civil airline pilots. As a result of the analysis, flight stress had a negative effect on job satisfaction, and pilots with low job satisfaction had a low awareness of safety culture. In particular, there was a difference in the effect of flight stress on job satisfaction and safety culture according to the airlines and rank of pilots. This suggests the necessity of developing customized stress management programs for each airline and pilot position. The study emphasizes the importance of managing pilots' stress and improving job satisfaction to reinforce the safety culture of the aviation industry. In addition, airlines should develop strategies to strengthen safety culture by reducing pilot stress and increasing job satisfaction. The result of this study is to be used as useful basic data for finding ways to manage pilots' stress and strengthen safety culture in the aviation industry.

Building Information Modeling(BIM) technology continues to develop and is now being applied to infrastructure facilities. As smart technology based on BIM is applied to the construction industry, the construction of the same data in a common environment is considered to be a very important step in various applications. This study was conducted on methods to establish an open BIM-based airport facility information common data environment. Therefore, this study develops the element technology to establish a common data environment for the integrated management of airport facility information, and aims to standardize data in the common data environment among various technologies and applications. In order to achieve the aim, in this study, the required technologies were derived by examining the common data environment and examining the civil engineering facility field and the case of integrated airport facility management. Through this, standards and development for information standard framework, information requirement level, BIM guidebook, and BIM library were developed in connection with national and higher standards. Through these standards, it is expected that the integrated management of various airport facilities will be efficiently carried out through a standard data platform in the future.

Before COVID-19 outbreak in 2019, it is the core value of airline's service to provide check-in service to passengers face to face. However, due to the global pandemic of COVID-19 outbreak, it is expected the airline service in the future would be dramatically changed from being contacted to being untacted with technology-based self service(TBSS). This paper analyzed the perception of passengers using self service technology and their acceptance. According to empirical analysis, it was found that the change of passengers' perception after COVID-19 has a significant positive effect on the innovation of TBSS. The innovation of TBSS(Effectiveness and certainty) had both significant positive effect on the passengers' acceptance on TBSS at airport. Among variables of TBSS, convenience rather than usefulness of TBSS had a significant positive effect on intention to use TBSS of passengers. It was proposed that airlines not only contribute to increase acceptance of TBSS but also inform and promote the prevention effect of TBSS and the importance of untact service to minimize congestion at check-in counter in airport.

Prototype UAMs are shown to us in the market. When the complete product is delivered to market, the efficiency of each UAMs can be compared by default. Before the complete product is shown to us, the comparative study on efficiency of UAMs is performed under the product cost estimation. The efficiency analysis result reveals that both of Lift & Cruise type and vectored thrust type show good efficiency at the initial stage of product. At the near terms stage, five years later from initial stage end, efficiency gets some change. Vectored thrust type of UAMs show best efficiency at the near term stage of product. Because UAMs will be used in urban area, Seoul is the place where the UAMs will be used first. The flying route from Seoul City Hall to Yongsan Park, National Assembly in Yeouido, and City Airport is no more than 10 km distance. For this short distance route, efficiency will make multi-rotor type UAM be prefered to other types. For long distance route or commuting route, life & cruise type and vectored thrust type of UAMs will be prefered on account of operational efficiency.

In the era of the 4th industrial revolution, airports around the world are rapidly pushing for smart airports. One ID service based on biometric technology to eliminate congestion and improve airport operation efficiency is one of them. In particular, biopass, which allows you to use the entire journey with one single token without an ID card or boarding pass from arrival at the airport to boarding an aircraft, is emerging as an important technology for smart airports. This study conducted an empirical analysis to identify factors that affect the intention to use in two aspects: the acceptance, and rejection of bio-pass by combining UTAUT and the innovative resistance model. As a result of the study, it was found that the relative advantages and compatibility had a positive effect on the intention to use, and the perceived risk had a negative effect on the intention to use through innovation resistance. This suggests that infrastructure expansion and usage expansion are needed to use time more efficiently at airports, and that the government, airlines, and airport operators need to cooperate to strengthen the security system to relieve users' psychological anxiety.

Aircraft accidents are characterized by a low probability of survival compared to other means of transportation, and the main causes appear to be human factors such as violation of regulations and communication. In order to activate the safety management system to prevent such accidents, an important key variable is to recognize the importance of safety culture and actively engage in safety behavior rather than simply emphasizing compliance with regulations to flight crew members. Even if there are well-established regulations, safety culture, The effectiveness varies depending on the safety atmosphere and level of safety behavior. In this study, the correlation between safety culture and safety behavior was verified through a survey of domestic flight crew members' awareness of safety culture. The results showed that fair culture and self-reporting were not activated enough to have a significant impact on safety behavior. We aim to improve the performance of the safety management system by confirming the characteristics of safety culture and safety behavior.

The ICAO (International civil aviation organization)recommended the implementation of the GANP (global air navigation plan) for strategic decision-making and air traffic management evaluation. In this study, we proposed a new method for finding the route distance from KPI (key performance indicator) 05 actual route extension presented for air traffic management evaluation. For this purpose, we collected trajectory data for one month and calculated the en-route distances using the methods presented in ICAO and the methods presented by this author. In the ICAO method, the intersection point must be estimated through the equation of a circle for radius 40 NM and the equation of a straight line for an inner and outer point close to a circle in the track data, and four flight distances are calculated to calculate the en-route distance. In the method presented in this study, two flight distances are calculated without estimating the intersection point to calculate the en-route distance. To determine the error between the two methods, we used the performance evaluation index RMSE (root mean square error) and the determination factor R² of the regression model.

The International Civil Aviation Organization (ICAO) introduced a safety management system in the aviation sector for aviation safety and mandated the implementation of safety management systems and national safety programs. The activation of the airline's safety management system is not just a requirement for organizational members to create and comply with necessary regulations, but a safety culture to promote and improve flight safety must be established within the organization. Therefore, the safety culture of airlines acts as a major key variable in the safety management system that directly affects safety performance. This study compared the data from the European pilot safety culture awareness, which was the basic data of the survey, with statistics on the safety culture awareness of domestic flight attendants to analyze the differences in safety culture between the two groups.

The purpose of this study is to establish the training standards for HF of aviation maintenance reflecting the growing relevance of aviation maintenance technicians' ability to perform their work for the safety and efficiency of airline operation. For this purpose, previous studies on the concept of human factors were examined, and the HF training standards of the advanced international aviation bureaus such as the International Civil Aviation Organization(ICAO), Federal Aviation Administration(FAA) and European Aviation Safety Agency(EASA) were compared with the operational technical standards of Korea Aviation Safety Law. In addition, the actual status of human factors education and training were examined for Korea's two full service carriers (FSC) and four of the low cost carriers (LCC). The study results revealed that Korea's human factors education and training standards were weak compared with international standards, and that most airlines were not able to systematically implement human factors education and training. These results complement the existing problem of training standards for aviation maintenance human factors in Korea and support the development of a standard model of the training course for aviation maintenance human factors which meets international standards.

Pilots have used checklist as a valuable tool to improve aviation safety and to reduce human error. A checklist however is too complex for a student pilot to use with less flight experience or time than a commercial pilot. It is agreed upon such complex checklist be a factor to threaten aviation safety for student pilots. This paper has focused on a checklist by dividing it into a couple of basic three flight procedures. Making exploratory case study of student pilots, researchers could analyze the correlation between checklist factors and those of human errors. First of all, it was necessary for student pilots to be educated professional knowledge regarding aircraft structures and engines to perform preflight inspection reducing human errors. Moreover it was recommended student pilots as well as maintenance crew confirm checklist together to enhance aviation safety.
