최근 발생한 국적항공기의 사고들은 항공기가 정상인 상태에서 조종사의 항공기 시스템에 대한 이해부족과 악 기상에 대한 대처미흡과 함께 운송용 조종사들의 수동착륙 기량이 현저하게 낮은 데에 그 원인을 찾을 수가 있다. 본 연구에서는 운송용 항공기 조종사들에 적용된 훈련프로그램의 실태와 이를 개선하기 위한 국제기구 및 항공선진국의 조치에 대한 문헌 연구와 함께 문제점을 분석하고 그 대안을 제시 하고자 한다. 항공사고 예방에 모의비행장치를 활용한 조종사 교육훈련이 큰 기여를 해온 것은 사실이다. 그러나 다양한 비정상 조건하에서 조종사들의 기량을 확인하기에 적합한 고가의 모의비행장치를 평이한 훈련과목, 환경이 우수한 특급 공항을 선택하여 운영한다는 것은 모의비행훈련의 기본 목적에 부합하지 않으므로 앞으로 조종사들의 기량향상을 위해서는 최악의 상황을 부여하고 안전하게 항공기를 운영하는 역량을 교육하고 평가할 필요가 있다. 또한 데이터에 기반을 둔 조종사 훈련프로그램인 APQ 및 EBT 의 조기 도입을 항공사와 정부가 협력하여 추진할 경우 국적항공사 소속 운송용 조종사들에게 비정밀 접근, 수동착륙 환경에서도 자신감 있게 항공기를 운영할 수 있는 경쟁력을 제공할 수 있을 것으로 판단된다.

Worldwide, air transport demand of this century is expanding rapidly, and each countries' demand is also increasing. Thus a number of low-cost carriers emerged in existing air transportation business sector and airman qualification check work regarding aviation safety management is increasing too. As the remedy for the result of aviation safety audit by ICAO and FAA in 2001 that governmental activity for aviation safety had been performed by a small number of aviation safety inspectors, airman qualification inspection system implemented by airlines was improved and the government has established the system that authorized airman qualification inspectors check airmen qualification with airlines according to the international trend. This study suggests the need of improvement of airman qualification inspection system that existing inspection system as the means of safety management can be transferred to Operations Safety Inspection(OSI) activity which is compliant with international standards.

The purpose of this paper is to analyze the relationship between the perception of organizational citizenship behavior and that of safety culture by airline pilots. Finding factors which composed of organizational citizenship behavior, this paper will prove the effects of those factors to the safety culture of an airline. Organizational citizenship behavior means the activities of members, based on their free will, to enhance organization's overall productivity and performance, which are, however, not officially and apparently approved by the organization. Safety culture is to contain the concept in the organization's protocol, procedure and policy affecting safety performance of the organization. According to the analysis, it was proven compliance of organizational citizenship behaviors has a positive effect on safety culture through job satisfaction. Moreover, altruism and individual initiative have a direct positive effect on safety behavior of pilots.

There are keen competitions among the air operators to recruit competent pilots, which could be adversely affect the safe operation of aircraft. This study is aimed to identify the correlation between the flight experience of the pilot of the air transport operator and competency on visual approach operation. About 2,400 sets of flight training data of several pilots of an air transport operator was analysed for this study. The analysis showed that most captains were able to make stabilized visual approach regardless of his/her flight experience of any type of aircraft, while the first officers were able to make a stabilized visual approach with more than 1,500 hours of flight experience for each rated type of aircraft. This should be considered during making policies for the supply and demand of pilots for the safe operation of air transport.

무인기의 기술 발전에 따른 운송, 통신중계, 교통감시, 산불감시 진화, 재해 재난대처 등 무인기의 민간 및 공공 수요 확대로, 무인기는 국가 공역으로의 운항이 요구되고 있으며 국가 공역으로의 안전한 진입을 위해서는 유인항공기 조종사에 의한 시각 감지 및 회피와 동일한 수준의 안전성을 제공하는 탐지회피 능력과 함께 신뢰성 높은 무인기 제어용 통신링크 확보가 필수적으로 요구되고 있다. 따라서, 본고에서는 무인기 제어용 통신링크에서 요구되는 기술적 특징 및 국내외 기술/표준화 동향을 파악하고 고신뢰성 무인기 제어용 통신링크 확보를 위한 기술적 및 표준화 이슈를 살펴보고자 한다.

According to the International Air Transport Association (IATA), 61% of the accidents occurred during the approach and landing phase of the flight, with 16% of the accidents caused by unstable access of the commercial aircraft. It was identified that the pilot's unstable approach and poor manipulation of correction led to accidents by continuing the excessive approach without go-around manuever. The causes of unstable access may vary, including airport approach procedures, pilot error, misplanning, workload, ATC (Air Traffic Contol) congestion, etc. In this study, we use the flight data analysis system to select domestic case airports and aircraft type where unstable approach events occur repeatedly. Through flight data analysis, including main events, airport approach procedures, pilot operations, as well as various environmental factors such as weather and geographical conditions at the airport. It aims to identify and eliminate the tendency of unstable approach events and the causes and risks of them to derive implications for mitigating unstable approach events and for developing navigation safety measures.

Rejected Takeoff Accidents are not common. but if occurred, it leads to big disaster From the year of 1959, when Jet Transport service opened, to the year of 2000, Rejected Takeoff accidents/incidents occurred total of 94 cases. All cases led to overrun, and major cause is to initiate stopping maneuvers over $V_1$, takeoff decision speed, according to National Transport Safety Board of America. Similar results are represented in Aviation Safety Reporting System of National Aeronautics and Space Administration. So I believe that it is worth studying if Airplane Flight Manual, which is the reference Performance criteria, is appropriate to operations of line pilots. The definition of $V_1$ has been revised a couple of times and Rejected Takeoff Certification Standards for Transport Airplanes was changed in 1998. It shows that up to now there are some portions unreasonable. This study focused on gathering the pilot's tendency for current Rejected Takeoff Procedures of K airlines and analyze the factors they concern. I chose B777 airplane and actually measured the recognition and reaction time of the rejected takeoff transitions through Simulators. And compared the results with the data of flight test and Airplane Flight Manual.
