The airline industry has been growing steadily since 2016 with more than 100 million air passengers, renewing the largest number of air passengers every year. Increasing air demand leads to an increase in air traffic in limited airspace, increasing the likelihood of accidents between aircraft. Due to the massive human and material damage caused by a single mistake, aviation safety is being heavily focused around the world to efficiently use limited airspace. Studies related to various human factors are underway as most of the aviation accidents are found to be caused by human factors, but research on human factors by controllers is insufficient while they are active in terms of control and operation. Given that 82% of air accidents caused by controllers are caused by human error, the importance of management of human error and changes in perception are urgently needed. This study aims to understand the seriousness of the controller's human error by analyzing the accident cases caused by the controller's human error using TEM to identify threats and errors and derive common human factors.

In this paper, it has implemented the design for the K-Line Operations Safety Audit(K-LOSA) designed to provide a proactive snapshot of system safety and flight crew performance before an incident and accident. It introduces the a LOSA and ten operating characteristics that have come to define LOSA methodology. According to the LOSA methodology, we explain the conceptual and detail design and implement the prototype for the data collected with LOSA collection tool.

Not only in aviation industry but also in other industries, safety data plays a key role to improve the level of safety performance. By analyzing safety data such as aviation safety report (text data), hazard can be identified and removed before it leads to a tragic accident. However, pre-processing of raw data (or natural language data) collected from each site should be carried out first to utilize proactive or predictive safety management system. As air traffic volume increases, the amount of data accumulated is also on the rise. Accordingly, there are clear limitation in analyzing data directly by manpower. In this paper, a topic prediction model for aviation safety mandatory report is proposed. In addition, the prediction accuracy of the proposed model was also verified using actual aviation safety mandatory report data. This research model is meaningful in that it not only effectively supports the current aviation safety mandatory report analysis work, but also can be applied to various data produced in the aviation safety field in the future.

There is a concern in the aviation community that pilot schedules can lead to fatigue and increased chance of an aviation accident. Yet despite this concern, there is little empirical studies showing the relationship between pilot fatigue and commercial aviation accidents. At this point of view, countering fatigue is a challenging proposition in complex aviation operations. However, with appropriate planning, many strategies can contribute to pilot alertness and flight safety. With proper education program, sustaining a physiological fit, a right knowledge about pilot fatigue can design a safety operations. On this study, I inquire into the ways of enhancing pilot's efficiency from fatigue.

EPTA(English Proficiency Test for Aviation) was not very aviation realistic test before 2019. Testee needed pass listening test first. Then testee could take speaking test. There were 20sets of speaking test. If the testee memorize well, he or she could pass the test easily even though he or she was not very good at English. So the pilot and the authority agreed to change the format of EPTA since 2016. Through development of new EPTA format, the Korea Transportation Safety Authority started new EPTA test since January, 2019. It has been one year since the new format of EPTA started. Now I try to survey satisfaction of new EPTA through questionnaire.

1970년대부터 시작된 우리나라의 경제개발계획은 성장위주의 급격한 산업화의 영향으로 각종교통수단의 안전은 물론 항공안전관리체계가 정착되지 않은 채 지속되어 2000년 초까지 발생된 항공기 사고에 의한 인적 물적 피해는 물론 사회적으로 막대한 비용을 부담 하고 있다. 특히, 발생된 항공기의 사고요인으로는 항공종사자의 인적요인에 의한 사고가 대부분으로 이를 사전 발견하고 예방할 수 있다면 항공기의 사고율은 대폭 감소시킬 수 있을 것이다. 따라서, 민간항공안전체계의 제도적인 개선대안을 도출하고자 항공안전관리체계를 3단계인 사전적인 예방체계, 사고발생시의 처리체계, 사고 후 수습체계로 구분하여 항공안전 체계의 개선을 위한 단계별 개선대안을 발굴 제시하였다. 발견된 항공안전의 위해 요인들로서는 관리기준과 규칙의 부재, 무관심과 준법정신의 결여 등이 주 요인들로서 이를 개선하기 위해서는 항공안전 체계의 제도적인 정착이 선행되어야 하고, 정부와 항공업계도 항공안전을 위한 위해요인들을 발굴하고 준법정신과 안전을 최우선시하는 마음의 자세가 모든 종사원들에게 확산되도록 유인책을 제공하여야 한다.

The world air transport industry has grown steadily with quantitative expansion. The volume of air transport in the world is skyrocketing with the open-sky trend. Air passengers from or to South Korea has shown 5% of annual growth for the last couple of decades which caused South Korea now ranking in 18th in the World for air transport market size. Quantitative expansion of Air transport affects in policy making of air transport operators, such as airports, airlines or authorities, directly and indirectly. Especially, Aviation Safety field should be supported by policy regime with the growth of air transport volume, assured resources for continuous monitoring is standing out as a vital factor. This study is to estimate social costs caused by aviation accidents and investment costs for aviation safety by airports, airlines and authorities as operators. Estimated investment costs for aviation safety verified by comparing and analysing them. Precedent studies were reviewed to refer research methodology to calculate aviation accident costs and safety costs of operators. Safety costs of operators was calculated with literature researches and interview surveys among professionals of each operators in rational range.

The objective of this study focuses on impacts of stress affecting CRM skills. According to KMOCT Report(1990-1999), aviation accident results in Korea imply that the crew is the primary cause in over 72.7% of accidents. So, CRM continues to receive increasing attention throughout the aviation community to prevent and decrease accidents caused by human factors. In addtion, developing and implementing CRM skills has been a formal part of aviation training. Stress may have a critical impact on the way a pilot assesses decision information, the way they make a decision, and the way they carry that decision through to completion.

In this paper, we propose the application of the Human Factors Analysis and Classification System(HFACS) to analyze an aircraft accident data. HFACS is a general human error framework originally developed and tested within the U.S military as a tool for investigating and analyzing the human causes of aviation accidents. It was examined that HFACS reliably accommodate all human causal factors associated with the commercial accidents. We found that the HFACS could be used as a reliable tool for investigating aircraft accidents including a single accident analysis.
