Despite the development of the aviation industry, aircraft accidents caused by human errors by flight crews continue to occur. In order to reduce such human error accidents, it is important to strengthen flight-related regulations and establish a safety culture in which pilots themselves seek to ensure flight safety, rather than requiring flight crew members to follow them. In this study, the sub-concept of safety culture was classified into three latent variables (safety management, safety atmosphere, and process culture) and eight measured variables to investigate the safety culture awareness of domestic flight crew. The survey results were analyzed by type of airline and flight crew. The purpose of this study is to present a plan to improve the performance of revitalizing the safety culture of domestic flight crew through an empirical comparative analysis according to the number of flight hours and years of service at the airline.

As the domestic aviation industry develops, demand for pilots is increasing. As a result, the demand for flight training using flight simulation training devices that implement the same or similar interior of aircraft is also increasing. Despite this increase in demand, domestic laws, regulations and management systems related to flight simulation training devices have remained unchanged since 2009. As a result, the criteria for designation of new or developed flight simulation training devices are ambiguous. In addition, proper improvement of the current system should be prioritized for designation of new devices such as UAM and VR, along with developing flight simulation training devices. It is intended to present measures to improve the domestic flight simulation training system by investigating and analyzing advanced cases overseas.

Although non-real time simulation and pilot based evaluations are available for the development of flight control computer prior to real flight tests, there are still many risky factors. The control law designed for prototype aircraft often leads to degraded performance from the initial design objectives, therefore, the proper evaluation methods should be applied such that flight control law designed can be verified in real flight environment. The one proposed in this paper is IFS(In-Flight Simulator). Currently, this system has been implemented into the F-18 HARV(High Angle of Attack Research Vehicle), SU-27 and F-16 VISTA(Variable stability. In flight Simulation Test Aircraft) programs. This paper addresses the concept of switching mechanism for FLCC(Flight Control Computer)-SWMC(Switching Mechanism Computer) using 1553B communication based on flight control law of advanced supersonic trainer. And, the fader logic of TFS(Transient Free Switch) and stand-by mode of reset '0' type are designed to reduce abrupt transient and minimize the integrator effect in pitch axis control law. It hans been turned out from the pilot evaluation in real time that the aircraft is controllable during the inter-conversion process through the flight control computer, and level 1 handling qualities are guaranteed. In addition, flight safety is maintained with an acceptable transient response during aggressive maneuver performed in severe flight conditions.

The flight simulator should be made like a actual flight. For the scene of sight, instrument should show the condition of flight and the pilot should catch the altitude, speed, pose and rate of lift of the airplane. This paper describes visual training program of driving airplane in practice. It is for beginners using joystick in PC, implements airplane physical equations. Flight simulator in it implements airplane panel parts in order to make simple modeling, And it uses rendering technology to implement vision parts of panel. It uses double buffering In make it faster and more efficient..

Cosmic radiation exposure of the flight crews in Korea has been managed by Radiation Safety Management around Living Life Act under Nuclear Safety and Security Commission. However, the domestic flight crews are excluded from the Act because of relatively low route dose exposure compared to that of international flight crews. But we found that the accumulated total annual dose of domestic flight crews is far from negligible because of relatively long total flight time and too many flights. In this study, to suggest the necessity of management of domestic flight crews' radiation exposure, we statistically analyzed domestic flight crew's accumulative annual dose by using cosmic radiation estimation models of the Civil Aviation Research Institute (CARI)-6M, Nowcast of Atmospheric Ionizing Radiation for Aviation Safety (NAIRAS), and Korean Radiation Exposure Assessment Model (KREAM) and compared with in-situ measurements of Liulin-6K LET spectrometer. As a result, the average exposure dose of domestic flight crews was found to be 0.5-0.8 mSv. We also expect that our result might provide the basis to include the domestic flight crews as radiation workers, not just international flight attendants.

The purpose of the study is to show the need for the development of standard materials which can be used for flight training and pilot practical tests in the future. In this paper the flight training and evaluation references of flight training institutes certified by the Ministry of Construction and Transportation(MOCT) are compared with references of the international organization such as ICAO and FAA. As a result it is found that the flight schools certified by the MOCT have used different references for flight training and evaluation. Therefore, this study suggests creation and operation of an expert advisory group to develop new standards for flight training and evaluation, so called " Flight Training Manual", in Korea.

UAVs(Unmanned Aerial Vehicles) have many applications in military and commercial areas. The flight control system of UAVs is more important than manned aircraft's because the mission of UAVs must be operated without a human pilot. But very heavy and expensive navigation system makes it difficult to develop UAV flight control system. In this research, GPS/IMU integrated navigation filter was developed for light weight/low cost flight control system of small UAVs. With this navigation filter, full flight control system which has real time operating capability has been developed. The performance of the flight control system is basically checked by HILSIM (Hardware In the Loop SIMulation). Finally, the flight control system is verified by showing performance test result under real flight environment.

항공기 분리보증은 자유비행의 핵심요구사항이다. 본 논문에서는 위임권한 확대, 공역 효율성 문제 등 자유비행의 실증적 문제해결을 위해 자율형 운항 알고리즘을 제안하고, 제안된 알고리즘과 포텐셜 필드 알고리즘을 모델링하여 두 가지 조건의 시나리오 상황에서 항공기 성능 데이터를 활용, 알고리즘 성능 및 충돌해결과 운항 자율성 효과 등을 측정하였다. 실험결과 자유비행 공역 하에서 자율형 운항 알고리즘이 포텐셜 필드 알고리즘보다 알고리즘 성능, 충돌해결, 운항 자율성 효과 측면에서 우수하였다.

Stress refers to various body reactions that occur when humans are stimulated by environmental conditions. The quality of education and flight skills can suffer if flight trainees are constantly subjected to high stress, even in the case of flight trainees, and as a result, it can harm becoming a pilot. It is therefore the aim of this study to identify stress factors (flight training, career, financial support, relationships with family and teachers) that student pilots face, to determine how these factors affect flight and academic immersion and abandonment, and to improve the quality of flight education.

Since the MPL (Multi-Crew Pilot License) Program was introduced in Korea in 2009, there has not been a single pilot licensed under the MPL Program. To successfully implement the MPL Program in Korea, it is necessary for an Approved Training Organization to develop the MPL Flight Instructor Training Program and foster excellent MPL Flight Instructors. However, there are no rules or guidelines regarding the MPL Flight Instructor Training Program in Korea. This study suggests the Training Specification for the MPL Flight Instructor, including the training syllabus, training and assessment methods. The MPL Flight Instructor Training Program should be composed of minimum 14-hour academic and practical training, which includes the concept of Competency-Based Training, CRM, Competency, Behavior Indicator and Assessment. To be qualified for the MPL Flight Instructor, candidates need to successfully complete the course and pass the practical test. In order to maintain the qualification, MPL Flight Instructors should comply to recency and recurrent training requirements.
