Multi-crew Pilot License (MPL) is an international pilot certification adopted by the International Civil Aviation Organization (ICAO) in 2006 under the recognition of the need for efficient and systematic pilot training including the education of pilots with advanced aviation technology and ability to respond to flight environment, resolution of the human factor problems of pilots, and provision of stable training tools for transport aircraft pilots for potential risk of pilot shortage in the future. South Korea also has prepared a legal basis for operating an MPL system in the Aviation Act in 2009, but there has been no domestic MPL qualifier. The biggest reason for this seems to be the insufficient domestic MPL training system. Therefore, it is necessary to benchmark the international standards of the ICAO, and to promote the development of the Korean MPL training system through revision and supplementation of laws and regulations in consideration of Korean circumstances.

In field of Aviation Maintenance, honest and expedite voluntary report of potential hazard provide airworthiness aircraft by eliminating or avoiding from dangerous factors of aircraft. Although it supports for safety flight, voluntary incident reporting system consist of Aviation practitioner and require cooperation of practitioner due to there are no forcibleness. These occur when positive safety culture and report culture are settled. In this regard, this study firstly identify the current status of Aviation Safety Reporting System in Korea. Then, this article also find out the level of reporting culture of the AMT(Aircraft Maintenance Technicians) and problems in reporting system. Finally, suggestions on the model of positive safety reporting culture in a field of aircraft maintenance.

현재 국내의 무인항공기 기술은 첨단성과 산업 경쟁력 측면에서 모두 항공 선진국에 비해 뒤쳐져 있지만 무인항공기를 기존의 유인 항공 체계에 편입하고 산업에 응용하고자 하는 세계적 노력을 방관만 할 수 없는 실정이다. 무인항공기는 기존의 항공 체계에 비교적 새로운 시스템이지만, ICAO는 체약국들과 항공업계가 무인항공시스템을 좀 더 이해하고 활용을 촉진할 수 있도록 많은 노력을 기울이고 있다. 특히 무인항공기시스템을 원격조종항공기시스템(RPAS)과 기타의 무인항공기시스템으로 분류하고, 가까운 장래에 RPAS를 유인항공기 영역에 통합해서 운용하기 위한 표준화 작업을 선도하고 있다. 이러한 취지에서 ICAO는 RPAS의 글로벌 운용을 위한 표준화를 추진하게 되었고, 본 연구에서는 ICAO 표준화 활동을 포함한 국내 RPAS 인증체계 구축 전략 연구를 수행하게 되었다. 따라서 본 논문에서는 RPAS 안전에 대한 국내외 규제 프레임워크를 분석하고 국내 RPAS 인증 체계 구축을 위한 전략을 제시하였다.

This paper addresses development of the ultra-light analog sun sensors for small satellite applications. The sun sensor is suitable for attitude determination for small satellite because of its small, light, low-cost, and low power consumption characteristics. The sun sensor is designed, manufactured and characteristic-tested with the target requirements of ${\pm}60^{\circ}$ FOV (Field of View) and pointing accuracy of ${\pm}2^{\circ}$. Since the sun sensor has nonlinear characteristics between output measurement voltage and incident angle of sunlight, a higher order calibration equation is required for error correction. The error was calculated by using a polynomial calibration equation that was computed by the least square method obtained from the measured voltages vs. angles characteristics. Finally, the accuracies of 1-axis and 2-axes sun sensors, which consist of 2 detectors, are compared.

The checklist currently used for Aviation safety inspection performed by ASIs consists of inspection groups and multiple items, it does not have structured hierarchy system which required to efficiently process aviation safety analysis. On this study, through mapping taxonomy of HFACS onto current checklist to secure structured hierarchy system and present a specification on systematic frequency and severity to perform safety risk assessment of detected hazard.

This paper describes boundary analysis for modeling Aircraft Carrier Sortie Generation System(CVSGS). An aircraft carrier, as a super system, is a warship going into battle by operating a number of aircraft on deck and it should be lay down a definition about aviation operations interacting between aircraft carrier and carrier air wing in small deck area. For this reason this paper models common aviation support system for generating sortie basic unit of carrier aviation operations unlike to general warship and defines boundaries between this system and aircraft carrier and carrier air wing. This paper analysis activities of aircraft carrier and embarked carrier air wing in carrier aviation operations, and analysis and defines boundaries Aircraft Carrier Sortie Generation System(CVSGS) to perform core functions in interacting between aircraft carrier and embarked carrier air wing.

항공산업의 성장과 항공안전에 대한 대중의 관심은 안전을 저해하는 위험에 대한 근본적인 분석과 관리에 대한 필요성을 대두시켜왔다. 특히 정비산업은 항공산업의 신뢰성과 안전성을 제공하는 산업으로 위험기반의 점검·감독을 통한 안전 관리가 요구되는 사업이다. 본 연구는 ICAO 및 항공 선진국에서 활용되고 있는 항공안전감독 체계를 기반으로 국내 정비산업 환경에 적절히 적용할 수 있는 체계를 제시하였다. 구체적으로, 정비 분야에서 발생 가능한 조직 측면의 위험을 두 가지로 분류하고, 두 종류의 위험에 대한 발생 가능성과 발생 시 예상되는 심각성을 중심으로 위험을 분석한다. 본 연구는 분석된 결과를 기반으로 제한된 점검·감독 자원을 효율적으로 활용하고 안전을 체계적으로 관리할 수 있는 개선 방안을 제시한다는데 그 의의가 있다.

Aviation safety is increasingly important to secure the safety of the Republic of Korea Air Force (ROKAF). A critical activity for enhancing aviation safety is to analyze an accident throughly and to identify causes that can explain it reasonably. The results of such a systematic accident investigation can be effectively used for improving information displays, task procedures, and training systems as well as for reorganizing team structure and communication control system. However, the current practice of analyzing aviation accidents in ROKAF is too superficial and simple to diagnose them systematically. Additionally, the current practice does not give a full consideration to human factors that have been identified as main causes of most of the aviation accidents. With this issue in mind, this study aims to suggest a new approach to analyzing aviation accidents related to human factors.The proposed method is developed on the basis of several models and frameworks about system safety, human error, and human-system interaction. Its application to forty-two human factors-related accidents, which have occurred in ROKAF during the last ten years, showed that the proposed method could be a useful tool for analyzing aviation accidents caused by human factors.

Korean aviation Turbulenc Guidance (KTG) system is developed using the operational unified model (UM) of the Korea Meteorological Administration (KMA) and pilot reports (PIREPs) over East Asia. The KTG system comprised of twenty turbulence diagnostics that represent various turbulence potentials and have the best forecasting skills, which are combined into a single ensemble-averaged index, namely KTG, at upper-(above FL250) and mid-(below FL250) levels. It is found that the overall performance of the KTG is higher than those produced from the one single best index, and satisfies the minimum criteria (80% accuracy) that the system is operationally useful in aviation industry.
