Flight control computers for unmanned aerial vehicles are avionics that require high reliability and are generally designed to be multiplexed for margins on failures. The multiplexed flight control computer should include an interface through discrete signals and CCDL for synchronization and fault separation between channels. With the development of unmanned aerial vehicle technology, various types of platforms such as AAM and LPI are being developed in the private and military, which require advanced control performance for high-performance flight control and SWaP optimization of onboard equipment. In this paper, we designed a optimized flight control computer architecture for unmanned aerial vehicles for multiplexing processing and performed a software design for input and output control. In addition, input/output processing performance was evaluated through the implemented flight control computer and input/output software.

The aviation has improved safety through technological innovation and strengthened flight safety through safety regulations and supervision by aviation authorities. As the industry's safety approach has evolved into a systematic approach to the aircraft system, airlines have established a safety management system. Technical defects or abnormal data in an aircraft can be warning signs that could lead to an accident, and the risk of an accident can be reduced by identifying and responding to these signs early. Therefore, management of abnormal warning signs is an essential element in promoting data-based decision-making and enhancing the operational efficiency and safety level of airlines. In this study, we present a model to statistically analyze quick access recorder (QAR) flight data in the preliminary analysis stage to analyze the patterns and causes of crab landing events that can lead to runway departures when landing an aircraft, and provide a precursor to a landing event. We aim to identify signs and causes and contribute to increasing the efficiency of safety management.

국내에서 생산된 항공기 및 관련 부품을 운용하기 위해서는 항공기 및 그것을 구성하고 있는 모든 부품의 제반 특성이 감항기준을 만족시킨다는 것이 입증되어 감함당국에 의해 승인되어야 한다. 항공기와 관련 부품의 승인은 법에 의한 감항 적합성 평가 절차를 따라야 하며, 이러한 평가 절차를 거쳐서 승인된 항공기는 비로소 감항성을 인정받아 운항이 허락되고, 또한 승인된 관련 부품은 항공기에 사용되어 최종적으로 고부가가치의 경쟁력을 얻을 수 있다.
