There are many ways to identify airline's perception of the safety program and safety culture. In particular, various studies are under way to measure airline safety culture and safety awareness of airline employees. Often, survey methods are used a lot, but there is a limit to understanding the complex and diverse aviation culture through surveys alone. Nevertheless, the Air Safety Management System (SMS) of the International Civil Aviation Organization (ICAO) emphasizes the importance of safety surveys as a means of ensuring awareness of safety culture. The safety surveys is effective in identifying and providing awareness of the relationship between employees and the Air Safety Program (SMS, Safety Management and Safety Culture aspects). In this study, we conducted a survey of Z Airlines flight attendants and cabin crew to compare their perception of safety programs and culture, and based on this survey, we would like to compare and analyze simple safety culture measurements and safety awareness.

The purpose of this study is to ensure safety by proactively identifying hazards that could be derived from changes in mission form and environment as the advanced aircraft such as F-35A stealth fighter, KC-330 Multi-role transport and tanker, RQ-4B high altitude unmanned reconnaissance aircraft, etc are introduced that the Republic of Korea Air Force(ROKAF) has never been operated so far. To this end, the safety management methods based on proactive and predictive approaches used in advanced countries(US Air Force, UK Royal Air Force, Royal Australian Air Force) operating aircraft types same or similar things being newly powered by the ROKAF were reviewed. In addition, the direction for improvement of the safety management methods operating in the ROKAF and the measures necessary for establishment of the new safety management techniques to be applied were suggested.

Even with the most advanced aviation technology benefits, aircraft accidents are constantly occurring while air passenger transportation volume is expected to double in the next 15 years. Since it is not possible to secure aviation safety only by the post aircraft accident safety action of accident investigations, it has been recognized and consensus has been formed that proactive and predictive prevention measures are necessary. In this sense, the aviation safety management system (SMS) was introduced in 2008 and has been carried out in earnest since 2011. SMS is a proactive and predictive aircraft accident preventive measure, which is a mechanism to eliminate the fundamental risk factors by approaching organizational factors beyond technological factors and human factors related to aviation safety. The methodology is to collect hazards in all the sites required for aircraft operations, to build a database, to analyze the risks, and through managing risks, to keep the risks acceptable or below. Therefore, the improper implementation of SMS indicates that the aircraft accident prevention is insufficient and it is to be directly connected with the aircraft accident. Reports of duty performance related hazards including their own errors are essential and most important in SMS. Under the policy of just culture for voluntary reporting, the guarantee of information providers' anonymity, non-punishment and non-blame should be basically secured, but to this end, under-reporting is stagnant due to lack of trust in their own organizations. It is necessary for the accountable executive(CEO) and senior management to take a leading role to foster the safety culture initiating from just culture with the safety consciousness, balancing between safety and profit for the organization. Though a Ministry of Land, Infrastructure and Transport's order, "Guidance on SMS Implementation" states the training required for the accountable executive(CEO) and senior management, it is not legally binding. Thus it is suggested that the SMS training completion certificates of accountable executive(CEO) and senior management be included in SMS approval application form that is legally required by "Korea Aviation Safety Program" in addition to other required documents such as a copy of SMS manual. Also, SMS related items are missing in the aircraft accident investigation, so that organizational factors in association with safety culture and risk management are not being investigated. This hinders from preventing future accidents, as the root cause cannot be identified. The Aircraft Accident Investigation Manuals issued by ICAO contain the SMS investigation wheres it is not included in the final report form of Annex 13 to the Convention on International Civil Aviation. In addition, the US National Transportation Safety Board(NTSB) that has been a substantial example of the aircraft accident investigation for the other accident investigation agencies worldwide does not appear to expand the scope of investigation activities further to SMS. For these reasons, it is believed that investigation agencies conducting their investigations under Annex 13 do not include SMS in the investigation items, and the aircraft accident investigators are hardly exposed to SMS investigation methods or techniques. In this respect, it is necessary to include the SMS investigation in the organization and management information of the final report format of Annex 13. In Korea as well, in the same manner, SMS item should be added to the final report format of the Operating Regulation of the Aircraft and Railway Accident Investigation Board. If such legal and institutional improvement methods are complemented, SMS will serve the purpose of aircraft accident prevention effectively and contribute to the improvement of aviation safety in the future.

오늘날 기술의 발전으로 시스템들은 점차 대형화 복잡화 되어가고 있다. 이처럼 점차 대형화 복잡화 되어가고 있는 시스템들은 더욱 커진 사고 및 고장에 대한 위험을 내재하게 된다. 또한 대형 복합 시스템에서 발생하는 사고 및 고장은 바로 큰 재산피해나 인명피해와 직결 될 수 있다. 따라서 체계적인 안전관리의 필요성이 점차 커지고 있다. 이에 대응하여 철도, 항공, 해양 등의 산업에서는 각 산업에 적합한 안전관리체계를 수립하려 노력하고 있으며, 표준 및 매뉴얼을 제정하여 보급에 앞장서고 있다. 또한 시스템에서 전장품 및 소프트웨어가 차지하는 비중이 커지면서 기능안전이 안전분야의 이슈가 되고 있다. 이에 따라 IEC 61508, ISO 26262, IEC 61511 등 기능안전관련 표준들이 제정되어 기능안전을 달성하기 위한 기반을 제공하고 있다. 한편 국내 철도산업에서도 철도안전법의 재정을 기점을 철도 산업전반에 걸쳐 많은 환경변화가 이뤄지고 있고 이에 대응하기 위해 철도 안전시스템을 바탕으로 한 안전관리체계를 구축하였다. 한편 다양한 운영체계를 갖고 있는 철도시설 및 운영기관이 존재하는 국가 철도 안전관리체계의 안전규제를 체계화하기 위해서는 체계적인 요구사항의 분석에 따른 시스템 아키텍처의 설정이 요구되고 있다. 이러한 아키텍처의 설정은 현재에 대한 분석과 미래의 철도안전시스템의 특성을 구조화하여 향후 비전을 프레임워크로 표현함으로서 구현이 가능해진다. 본 논문에서는 현재의 안전관리체계의 도입 배경 및 도입 현황에 대해서 분석하고, 최근 기존의 안전관리체계와 더불어 최근에 안전분야에서 이슈가 되고 있는 기능안전 표준을 반영한 안전관리체계의 구축을 위해 안전관리체계에 대한 아키텍처를 구현하고자 하며 이때, 모델링을 바탕으로 한 접근을 제시한다.

As all flight training institutions in Korea were approved by the Ministry of Land, Infrastructure and Transport (MOLIT) as aviation training organizations (ATO), safety management based on the Aviation Safety Management System (SMS) became mandatory. However, even though safety management using SMS has become mandatory, the performance of aviation safety voluntary report, which is the core of the system, remains low compared to other countries. The current address of SMS, a ATO, is like a watermill without water. The present study is to find out why voluntary aviation safety reports, which is equivalent to water from waterwheel, is underperforming and to suggest ways to revitalize it.

The aviation has improved safety through technological innovation and strengthened flight safety through safety regulations and supervision by aviation authorities. As the industry's safety approach has evolved into a systematic approach to the aircraft system, airlines have established a safety management system. Technical defects or abnormal data in an aircraft can be warning signs that could lead to an accident, and the risk of an accident can be reduced by identifying and responding to these signs early. Therefore, management of abnormal warning signs is an essential element in promoting data-based decision-making and enhancing the operational efficiency and safety level of airlines. In this study, we present a model to statistically analyze quick access recorder (QAR) flight data in the preliminary analysis stage to analyze the patterns and causes of crab landing events that can lead to runway departures when landing an aircraft, and provide a precursor to a landing event. We aim to identify signs and causes and contribute to increasing the efficiency of safety management.

운항승무원 갈등에 의한 항공기 사고사례에서 볼 수 있듯이, 기장과 부기장 간 갈등이 주요원인이 되어 항공기가 추락하는 등 안전사고가 발생하고 있다. 갈등관련 기장 및 부기장 인터뷰 결과, 기장 승급 기준 불투명, 무리한 비행스케줄에 따른 불만, 대립적인 노사문제, 기장의 권위주의, 군 경력자와 민간비행훈련원 출신 간에 갈등, 격무와 스트레스 등이 주요 갈등원인 이었다. 항공안전관리를 위해서는 갈등원인을 정확히 진단하여 부정적인 갈등이 표출되기 전에 해소시켜야 한다. 또한 건전한 조직문화를 위해서 상호신뢰와 CRM을 바탕으로 한 안전문화를 정착시킬 수 있도록 갈등관리에 대한 지속적인 연구 및 해소대책 강구가 필요하다. 이에 따라 본 연구에서는 갈등에 의한 항공기 사고사례와 운항승무원 갈등원인을 시스템적, 조직 문화적, CRM 적 측면에서 분석하여 각 분야별로 갈등해소 방안을 제시하였다.
