Safety and Reliability assessments of Avionics Parts must be conducted essentially in the step of disign and manufacture as it constitutes a major field of aircraft critical operation. Recently Avionics parts fabrication techniques are continuously developing by applying digital techniques. Airborne computer is being adopted on an aircraft for flight is being adopted on an aircraft for flight safety augmentation and simplification of controls including reduction of human error. Therefore inspection and evaluation procedures should be developed in order to accomodate such trends. The number of avionics parts is approximitely 72% of total TSO parts, so it is expected high added-values through manufactures of TSO parts in aircraft industries. Particuarly avionics parts must be manufacturered with our own technology to be used in Mid-class aircraft which will be developed soon. Along with this, preparation of Certification Procedures is essential for Avionics Parts.

국토교통부는 공항의 지상조업 근로자 근무환경을 개선하기 위하여 2019년 11월부터 40개 과제를 발굴·시행하는 등 노력해 왔으나, 근원적인 안전관리체계 개선이 필요하다는 판단에 따라, 노조와 지상조업사 등 관계기관과 간담회를 통해 수렴한 의견을 바탕으로 국토교통부는 승객이동, 항공기 견인 등 항공운항의 필수 역할을 하는 지상조업의 서비스 및 안전성을 높이기 위해 '지상조업 안전관리 강화방안'을 수립했다. 본 논문은 공항에서 지상조업 시 안전하고 신속하게 할 수 있도록 하는 '공항용 원격 주행 멀티카트' 기술을 제안한다. 현장이 아닌 컨트롤러를 이용한 원격으로 주행하여 지상조업자의 안전을 보장하고, 카트에 멀티파츠를 장착하여 지장조업 장비의 유지 보수를 편리하게 관리하며 라이다 센서, 카메라, 적외선 센서 등을 이용하여 장애물을 피하는 멀티카트를 구현하여 공항 지상조업의 발전을 선도할 것이다.

능동형 전자주사레이더, 일명 AESA 레이더는 21세기 항공무기체계 분야의 핵심 단어 중 하나다. F-22와 유러파이터 F/A-18E/F 슈퍼호넷과 같은 최첨단 미래 전투기는 물론 F-15와 F-16 같은 기존 전투기의 성능 개량을 위해 꼭 갖춰야 할 필수장비 중 하나로 평가받고 있기 때문이다. 서방세계뿐만 아니라 러시아 및 중국과 같은 공산권 국가의 AESA 레이더 개발 및 확보 노력 역시 상상을 초월하는 수준. 미래 전투기의 필수장비로 인식되고 있으며 기존 전투기의 성능 향상을 위한 만병통치약처럼 인식되고 있는 AESA 레이더에 대해 알아본다.

This paper is a study of TPS Migration to a multi-purpose ATS which is used for functional testing of Avionics parts. The dedicated ATS used for the performance test of avionics parts has a lot of difficulties in domestic MRO companies that carry out maintenance of high-level avionics ranging from tens of thousands won to several hundreds of billions won. For this reason, in this paper, I have studied the procedure of TPS migration to use the wire-harness in generators used in A aircraft, which is a maintenance product using a dedicated ATS, as a general-purpose ATS. Through the proposed study, We confirmed the 100% performance verification after the TPS migration from the proprietary to the general purpose. It is possible to expand infinitely through the standardization of the procedure.

In recent years, model-based design techniques have been used as a way to support cost reduction and safety certification in the development of avionics systems. In order to support performance analysis and safety analysis of aircraft and avionics equipment (item) using model based design, we developed a multi-domain simulation environment that inter-works with heterogeneous simulators. We present a multi-domain simulation environment that can verify air data computers and integrated multi-function probes at the aircraft level. The model was developed by Simulink and the flight simulator X-Plane 10 was used to verify the model at the aircraft level. Avionics model functions were tested at the aircraft level and the air data errors of the model and flight simulator were measured within 0.1%.

This paper presents a method for analyzing the reliability of hardware electronic equipment, taking into account failures caused by radiation. Traditional reliability analysis primarily focuses on the wear out failure rate and often neglects the impact of radiation failure rates. We calculate the wear out failure rate through physics of failure analysis, while the radiation failure rate is semi-empirically estimated using the Verilog Fault Injection tool. Our approach aims to ensure reliability early in the development process, potentially reducing development time and costs by identifying circuit vulnerabilities in advance. As an illustrative example, we conducted a reliability analysis on the ISCAS85 circuit. Our results demonstrate the effectiveness of our method compared to traditional reliability analysis tools. This thorough analysis is crucial for ensuring the reliability of FPGAs in environments with high radiation exposure, such as in aviation and space applications.

ASDR(Avionic System Development Rig) is used as a development tool during the design and development of the ASC/OFP and then can be used as a maintenance tool after developing them for a military aircraft. This paper describes the overall structure and the important features of KO-1 ASDR, especially about the dynamic simultion of inertial and air data sensors.
