This technical paper deals the practical transformation algorithms between several lunar reference frames which will be used for Korea pathfinder lunar orbiter (KPLO) flight operation. Despite of various lunar reference frame definitions already exist, use of a common transformation algorithm while establishing lunar reference frame is very important for all members related to KPLO mission. This is because use of slight different parameters during frame transformation may result significant misleading while reprocessing data based on KPLO flight dynamics. Therefore, details of practical transformation algorithms for the KPLO mission specific lunar reference frames is presented with step by step implementation procedures. Examples of transformation results are also presented to support KPLO flight dynamics data user community which is expected to give practical guidelines while post processing the data as their needs. With this technical paper, common understandings of reference frames that will be used throughout not only the KPLO flight operation but also science data reprocessing can be established. It is expected to eliminate, or at least minimize, unnecessary confusion among all of the KPLO mission members including: Korea Aerospace Research Institute (KARI), National Aeronautics and Space Administration (NASA) as well as other organizations participating in KPLO payload development and operation, or further lunar science community world-wide who are interested in KPLO science data post processing.

현재 항공 산업 분야에 우수한 조종사를 공급하기 위해 전 세계적으로 전문교육기관 제도 (ATO; approved training organization)를 활용하고 있다. 세계적으로 활용되는 이 제도는 각 국가에 맞는 실정으로 변형되어 활용되고 있다. 본 연구에서는 우리나라 조종사 양성 전문교육기관의 운영방식 및 교육 환경을 자세히 살펴보고, 국제민간항공기구의 국제표준, 미국, 유럽, 캐나다 등과 일본, 중국, 싱가포르 등 주변국의 비행 교육기관 운영방식 및 비행교육 환경을 비교하여 차이점을 도출함으로써 우리나라 전문교육기관 제도와 어떠한 차이를 보이는지를 비교하였다. 이러한 비교자료를 기반으로 해당 업무 종사자들의 설문 조사를 통해 국내 항공안전법 전문교육기관 지정기준에서 설정하고 있는 학과 수업 양에 대한 만족도가 설문대상의 특성에 따라 큰 차이가 있었고 학과 수업과목에 따라 중요도의 차이가 발생하였다.

증거기반훈련(EBT)은 고속화되고 대형화되는 항공운송시장의 안전 운항을 위해, 실제 항공기 사고, 준사고, 운항, 훈련 데이터(Evidence)를 기반으로 조종사의 역량(Competency) 및 자신감(Confidence)을 향상하고 문제해결을 위한 회복력(Resilience)을 강화하는 훈련·평가 프로그램이다. 이러한 증거기반훈련(EBT)을 전문교육기관의 교육 체계에 적용하고 문제점을 개선하기 위해, 현재의 평가 기준에서 EBT의 핵심역량을 적용한 평가 기준으로의 개선과 실기시험관 및 교관 표준화를 위한 제도 개선, 모의비행훈련장치의 활용이라는 3가지 개선방안을 제시하였다.

In this report US and Korea civil and military simulator certification system is researched, and a plan for improvement is proposed. Korean simulator certification system should adopt FAA's system and improve upon it. Certification criteria should have a basis on FAA certification criteria and add military operation characteristics selectively. Flight test data, used as comparison criteria in certification, should be acquired in package during aircraft development or overseas acquisition. The establishment of certification system is expected to improve external credibility and improve competitiveness in overseas market.

항공 산업의 소비 수요가 증가함에 따라 국내에서 수행할 수 있는 인증체계 및 비행시험 운영에 필요한 연구가 요구된다. 이에 따라 본 논문에서는 국내 민항기 KC-100, 군용기 T-50 사례와 국외 FAA(Federal Aviation Administration), CAAC(Civil Aviation Administration of China) 기관의 비행시험 관련 문건을 바탕으로 개발 및 개조 중에 있는 항공기에 대한 성능검증, 시험평가 및 안전성 인증을 위한 비행시험 운영 절차와 안전 관리 프로그램 개발 연구를 수행하였다. 또한 항공기 비행시험 절차에 적용할 수 있는 FTSC(Flight Test Safety Committee)의 모범사례(Best Practices)를 조사 분석하였다.

Recently, domestic small airport development plans are being promoted centering on islands, and among them, Baengnyeong Island Airport is located very close to North Korea due to its geographical characteristics. In particular, since it is located in the P-518, which is prohibited airspace, it is essential to configure the arrival/departure flight procedure route similarly to the current ship in terms of securing flight safety. Therefore, in this study, a plan for airport location and facility scale was proposed by focusing on the runway operated for the purpose of aircraft operation through consultations with the Ministry of National Defense. It was proposed to meet the standards of the Airport Facility Act as an airport dedicated to domestic flights for airside facilities such as runway length and direction, target aircraft, landing pad, apron, runway and taxiway width appropriate for the topographical characteristics of Baengnyeong Island. As a result, the flight procedure is generally established as a two-way visual flight, but the 10-way arrival/departure procedure was planned to be changed to an instrument (non-precision) according to the specificity of the region. In addition, a flight procedure was established and presented for safe and systematic operation by reflecting the changes in airport facility size (landing pad, runway end safety area, etc.) following the change in instrument flight procedure in the visual flight procedure.

비행시험은 항공기 개발 및 인증을 비롯한 항공기 수명 주기에서 감항성 유지를 위해 반드시 수행해야 하는 중요한 절차로서 관련 표준에 대한 적합성을 입증 또는 검증하기 위한 것이다. 비행시험 항공사고 분석 결과는 항공기 자체 요소뿐만 아니라 다양한 복합 원인에 의해 발생되었음을 확인한다. 국제민간항공기구는 항공기 사고 방지를 위해 안전관리시스템 구축 및 이행을 권고하고 있으나 비행시험의 특수성은 반영되어 있지 않다. 이에 항공선진국들은 이해관계자의 비행시험 안전관리 수행을 지원하기 위해 별도의 기준을 제공하고 있다. 본 논문에서는 국내 국가종합비행성능시험장 구축에 맞춰 항공선진국의 관련 규정을 조사, 분석하고 조직 구성, 안전 및 리스크 관리, 비행 운영, 인력 관리, 행정 사항 등의 내용을 포함하는 비행시험 운영 매뉴얼 개발을 위한 정부차원의 기준 안을 제시한다.

EMSS is the organic system offering quick and efficient transfer and treatment for those who need an emergency service. For EMS aviation operation is the important transportation for the common benefits. There are several types of aviation operation. Among the different types of the operations, helicopter operation is very common because it is free from any locations. Notwithstanding the benefit, various types of EMS helicopter accidents and incidents are occurred because of its poor operation condition. In South Korea, even though so much effort was put to decrease the accidents rates, there are still many accidents happening by fire helicopters and the forest service helicopters. Therefore, in order to regularize the EMSH operation, measures for the aviation safety have to be prepared. This research is, related to the EMSH, focused on the suggestion of safety measure for the EMSH in Korea based on the accidents analysis in various countries.

In the case of the Navy, if some of the co-pilots are included in the long-term promotion process due to the limited number of co-pilots, operational flight and administrative tasks will be added to the co-pilots not included in the rest of the Pilot in commander process. Therefore, to solve this problem, the co-pilot who has passed the PQS step-by-step process minimizes the personnel gap in the flight operation unit through a system that evaluates whether it is possible to perform its duties as a co-pilot through actual flight after entering the school. The advantage of the PQS course is that you can control flight plans on your own and minimize gaps in flight and ground work while carrying out the curriculum, but you can't focus on education or improve your skills due to irregular training flight cycles. Therefore, in this study, after collecting opinions on effective flight cycles through a survey of pilots of P-3C, the Navy's fixed-wing aircraft representative, we will analyze the association of aircraft volume performance by flight cycle to derive the optimal flight cycle of the P-3C pilot course.

For the flight education, it needs a lot of money. Most of people become airline transportation pilots after completing a course. Therefore it is important to select superior students who adapt themselves to flight for flying education. At present, students who have a good high school record and SAT(Scholastic Aptitude Test) are chosen, and educated at Hankuk aviation university, department of aeronautical science and flight operation. This research studies the professor's recognition of the relationship between practical flight skills and high school record, university grades, and SAT grades.. On this analysis result, there are significant differences between belonging education, completion and work experience.
