Airlines tried to introduce training programs in connection with practical work in order to provide more effective education and training. To this end, airlines have been conducting evidence-based training(EBT) to strengthen the practical capabilities of aviation personnel and enhance safety culture. Airlines can systematically evaluate the capabilities and practical capabilities of aviation personnel by analyzing operational data and case studies for effective EBT model development. In addition, EBT models can be constructed by applying technical methods such as crew resource management (CRM) and a holistic approach that includes human factors. Due to the introduction of EBT, airlines will establish diagnostic and feedback systems for pilots' practical work, provide personalized education, and establish an education and training system that verifies the effectiveness of education through educational outcomes.

현대사회의 산업 현장에서 기계가 사람들을 대체하면서 작업의 효율을 높이고 있다. 많은 산업 분야에서 사람들을 기계로 대체하고 있는데, 재해 및 사고 현장이나 위험 지역 조사 등에 대한 탐사 활동은 대부분 인력이 차지하고 있으며, 탐사 활동에 참여하는 많은 인력들은 2차, 3차 사고에 쉽게 노출되어 있으며, 그로 인한 인력소모가 심하다. 따라서 우리는 인력 투입 전 사고 및 재난 현장이나 위험 지역에 인력을 투입하기 전 피해를 최소화 하면서 탐사 인력에 대한 안전이 보장된 근무 환경을 개선 시키기 위해서 무인 탐사차량을 생각하게 되었다. 무인 탐사 차량에는 아두이노와 라즈베리파이를 메인으로 삼았고, 현장의 온도와 습도, 화재여부, 가스여부를 측정하기 위한 센서들은 아두이노에 연결하고, 카메라와 라이다센서의 경우 라즈베리파이에 연결을 하였다. 그리고 모든 데이터값은 블루투스와 와이파이 모듈을 통해서 수신받을 수 있게 프로그램을 구성하였다.

In this paper, the activities of North America to enhance the flight safety of helicopter were introduced. In North America, by 2009, 49% of worldwide civil helicopters are in operation. The development trends of North America to enhance the flight safety of helicopter are expected to have a significant impact to the other helicopter operating areas. The analysis of the case of Gulf of Mexico where large fleet of Helicopter in operations, FAA's NextGen program, and the Canadian plan to comply with the ICAO's Aviation System Block Upgrades plan shows the direction of helicopter avionic development for enhancing the flight safety of helicopter.

국제 공동 가스터빈 엔진 개발 프로그램인 ASE120 사업은 항공기용 터보팬 엔진을 Low Emission 산업용 엔진으로의 개조사업으로서 현대우주항공, AlliedSignal, AIDC(대만), SPHT(대만) 등이 참여하고 있다. 본 사업을 통한 주요 개조 부품인 연소기의 경우, 산업용 엔진의 특성상 장시간의 수명이 보장되어야 하고 Dry Low NOx 연소실 형태로 배기가스 규제의 요구조건을 만족하여야 하므로 일반 항공기용 연소기와 구조적으로 첨예한 변화가 발생하여 구조 및 수명해석을 통한 구조적 안전성과 요구 수명에 대한 평가가 절대적으로 요구되었다. 당 엔진의 요구수명은 30년으로 cold section part의 경우 180,000시간, hot section의 경우 90,000시간의 수명을 목표로 개발되었으며, 연소기 최적설계를 위해 구조/수명 해석결과가 개발과정 중 설계에 지속적으로 반영되어 추진되었다. 연소기의 구조해석은 해석용 tool로서 ANSYS53을 활용하였고 수명예측은 AlliedSignal사의 Material Database 및 Inconel사 재질 data를 근간으로 수행하였다.

As our whole society has become increasingly aware of safety and emphasizes the importance of preventing safety accidents, the airline cabin service sector is also facing a strong demand to improve practical system for aviation safety education. In this regard, the development of appropriate safety education programs and the getting of human resources who can develop and operate such programs are becoming key issues. This study aims to provide academic and practical implications for safety education and training in airline cabins by reconfirming the importance and direction of safety education in the context of airline cabin services, and by specifying and establishing qualification requirements for personnel who develop and operate such safety programs. To this end, we review the content that should be included in safety training programs, the qualifications required of developers, managers, instructors, and examiners who develop or operate such programs, and how safety training programs can be continually improved as relevant conditions change in the future. In addition, we have also suggested ways to train appropriate managers, instructors, and examiners, including improving the compensation system for them, and how to effectively manage trainees. In order to secure a higher level of aviation safety in the future, it will be necessary to continue research on the development of more diverse and high-quality aviation safety education programs and the training of related personnel.

As demand for best practices relative to flight test safety management operations and processes in the aviation industry grows, standards for such aspects of the industry in Korea should be examined. Therefore, in this paper, we conducted flight test operation processes and safety management program development studies based on documents related to flight tests of the Korean civil aviation KC-100, the military aircraft T-50, the FAA (Federal Aviation Administration), and CAAC (Civil Aviation Administration of China) for performance validation, test evaluation and safety certification for aircraft under development and remodeling. In addition, we introduced and analyzed best practices of the FTSC (Flight Test Safety Committee) applicable to aircraft flight test processes.

The purpose of this study is to analyze the effect of self-esteem on the safety culture and safety behavior of airline pilots and to confirm whether job satisfaction has a mediating effect in these relationships. It was examined whether self-esteem directly affects safety culture and safety behavior, and indirectly through job satisfaction. As a result of the study, self-esteem did not have a direct significant effect on safety culture, but indirectly had a positive effect through job satisfaction. In addition, self-esteem had a direct significant positive effect on safety behavior, and job satisfaction partially mediated this relationship. This suggests that pilots with higher self-esteem practice safety behavior more actively, and job satisfaction can promote such behavior. These results show the importance of organizational support such as programs and support for enhancing pilots' self-esteem, fair compensation for improving job satisfaction, improving working environment, and providing career development opportunities in airlines, and are intended to be used as basic data for this.

As the scale of airborne system software increases, the use of OOT (Object-Oriented Technology) is increasing for functional expansion, efficient development, and code reuse, but the verification method for airborne object-oriented software is conducted from the perspective of the existing procedure-oriented program. The purpose of this paper was to analyze the characteristics of OOT and the vulnerabilities derived from the functional characteristics of OOT, and present a verification method applicable to each software development process (Design, Coding and Testing) to ensure the functional safety integrity of aviation software to which OOT is applied. Additionally, we analyzed the meaning of the static analysis results among the step-by-step verification measures proposed by applying LDRA, a static analysis automation tool, to PX4, an open source used to implement flight control software.

The operational flight program(OFP) which has the functions of I/O processing with avionics, flight control logic calculation, fault diagnosis and redundancy mode is embedded in the flight control computer of Smart UAV. The OFP was developed in the environment of PowerPC 755 processor and VxWorks 5.5 real-time operating system. The OFP consists of memory access module, device I/O signal processing module and flight control logic module, and each module was designed to hierarchical structure. Memory access and signal processing modules were verified from bench test, and flight control logic module was verified from hardware-in-the-loop simulation(HILS) test, ground integration test, tethered test and flight test. This paper describes development environment, software structure, verification and management method of the OFP.

As the system requirements of performance, weight, cost are increasing, the needs of electronic parts which have high performance and efficiency are growing. To satisfy such requirements, demand of high performance and rapid upgraded commercial parts is also increasing compared to NASA or ESA standard parts. Especially, commercial PEM(Plastic Encapsulated Microcircuit) parts are applied in many space programs and research is continuing to broaden its application area. In this paper, concerns and verification trends of commercial PEM parts in space applications are introduced.
