In order to achieve successful flight training results, various studies on pilot aptitude have been conducted. In this study, we examined the aptitude for the pilots using the teacher aptitude test tool. As a result, the student pilots showed a high aptitude score suitable for conducting aviation training, and the A-type personality type was overwhelmingly large. The study satisfaction of student pilots was classified into educational contents, educational methods, educational environment and facilities, and flight instructors using the questionnaire related to the satisfaction of learning. As a result, the satisfaction of flight instructor among four factors was found to be a major factor in improving flight performance.

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.

The Lion Air JT610 accident in Indonesia in October 2018, along with the Ethiopian Airline ET302 accident in March 2019, is an significant aircraft accident that detects defects of the B737MAX aircraft. Shortly after the accident, the FAA prohibited operation of the aircraft. This action has affected the market environment of airlines and aircraft manufacturers around the world. In October 2019, Indonesian Traffic Safety Committee released an accident investigation report for Lion Air JT610, which concluded that the causes of the accident were MCAS design defects, lack of education and training, and errors in the repair process. This paper summarizes the flight control system of the B737MAX aircraft, the causes of the accident based on the final accident investigation report, and provides considerations for aircraft design and retrofit.

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.

본 연구는 부조종사 자격증명 (MPL) 제도 도입을 위한 시범운영 로드맵에 관한 연구로서, MPL 제도의 국내 도입은 기존의 조종사 자격제도와는 다른 역량 (Competency) 기반의 신개념 조종인력 양성 및 자격제도로서 새로운 조종사 교육 및 자격제도이다. 따라서 MPL 제도의 국내 도입은 초기 규정 확보, 훈련사업자 또는 교육생 확보 등의 제반 사항 준비 및 훈련 인프라 구축이 어려울 수 있으므로 MPL 제도의 성공적인 도입을 위해서는 시범운영에 필요한 로드맵이 매우 중요하다. 국내 항공시장에서 MPL 제도가 검증된 훈련프로그램 및 자격체계를 확보하기 위해서는 정부와 항공업계 구성원이 공동으로 참여하여 MPL 훈련프로그램 과정의 점검, 평가 및 개선사항의 도출해내는 국내 비행 환경에 적합한 MPL 제도의 시범운영 로드맵의 중요성을 강조하고자 한다.

Aviation ICT technology is a convergence technology between aviation and electronics, and has a wide variety of applications, including navigation and education. Among them, in the field of aerial pilot training, there are many problems such as the possibility of accidents during training and the lack of coping skills for various situations. This raises the need for a simulated pilot training system similar to actual training. In this paper, pilot training data were collected in pilot training system using VR/AR to increase immersion in flight training, and Customized Pilot Training Platform with Collaborative Deep Learning in VR/AR Environment that can recommend effective training courses to pilots is proposed. To verify the accuracy of the recommendation, the performance of the proposed collaborative deep learning algorithm with the existing recommendation algorithm was evaluated, and the flight test score was measured based on the pilot's training data base, and the deviations of each result were compared. The proposed service platform can expect more reliable recommendation results than previous studies, and the user survey for verification showed high satisfaction.

Black carbon concentrations were measured along the altitude at various locations using a drone coupled with a small black carbon detector. The measurement locations are Eunseok Mountain, downtown, four places in KOREATECH campus, Byeongcheon, Cheonan, Chungcheongnam-do, and Chungbu Expressway in Ochang-eup, Cheongju, Chungcheongbuk-do. The average concentration of black carbon measured in Eunseok Mountain was $1.64{\mu}g/m^3$ and the average concentration near the Chungbu Expressway was measured to be $3.86{\mu}g/m^3$. The average concentrations of four places inside campus ranged from 1.37 to $2.67{\mu}g/m^3$. The concentration of black carbon at all places tended to be slightly decreased according to the altitude, but the influence of pollution source, geometry, wind speed, and wind direction are thought to be larger than the effect of altitude. Effect of air flow caused by drone flight on the measurement of black carbon were investigated and it resulted in that the measurement of BC concentration was affected by less than 5%.

We studied the functional roles of two types of calls, mew calls and mobbing calls, of the black-tailed gull (Larus crassirostris) by examining responses of mixed flocks of gulls to the playback calls. Playback experiments were conducted on four days between 11 May and 5 June 2007 at 16 sites in Sinjindo-ri and Dowhang-ri, Taean-gun, Chungnam province and Imjado, Sinan-gun, Jeonnam province, South Korea. We examined the anti-predator responses of the gulls to the playback trials. We found that gull flocks initially responded to mew call playbacks by mobbing in less than half of playback trials (6/14) while all trials involving playbacks of the mobbing call and control (group mobbing) call evoked mobbing. When trials in which no response was recorded were excluded, we found that the gulls' responses to mobbing and group mobbing call playbacks was more intense than their response to mew call playbacks, in that gulls mobbed longer, more gulls responded, and gulls took flight after a shorter time interval. However, the intensity of the gulls' response did not differ in mobbing call and group mobbing call playbacks. The results of this study suggest that the mixed-species flocks of gulls discriminate between the mew calls and the mobbing calls.

Avionics is a compound word of aviation and electronics that began to be used in the late 1930s. In the components or sub-systems installed to the aircraft, avionics is something that works by electronic technology. In the past, the aircraft mate, the flight engineer, and the radar operators performed the work on board the aircraft but the modern aircraft have replaced these tasks with avionics. the aircraft mechanics who maintain and manage such complex aircraft must have expertise and technics with the development of avionics to maintain aircraft airworthiness. This paper is about the introduction of domestic avionics qualification system and the development of avionics maintenance technology. For this, the SWOT analysis is performed by identifying the internal and external environment. And recommend the strategy and direction of domestic avionics qualification and education system.
