Abstract

RTCA DO-178C is a development guideline to ensure aircraft system airworthiness. However, there is an opinion that the application of DO-178C to the development of UAV of more than MTOW 150 kg is over regulated because the severity of the risk from UAV is lower than that of normal aircraft. To address issue, EASA and FAA have been working on the Re-Engineering and Streamlining the Standards for Avionics Certification(RESSAC) project since 2016 with the goal of establishing a new certification scheme that simplifies existing aircraft certification procedures and standards. This paper analyzes the current DO-178C certification process and presents advantages by comparing and analyzing the new RESSAC certification process, which simplifies processes and outputs in comparing with the DO-178C certification process, while it ensures flight safety of the vehicle.

RTCA DO-178C는 항공기 시스템의 감항성을 보장하기 위한 소프트웨어 개발 지침서이다. 하지만, DO-178C는 최대이륙중량 150kg 이상의 무인기 인증에 적용하는 것은 무인기로 인한 위험의 심각도(severity)가 보통의 항공기보다 낮기 때문에 과도한 규제라는 의견이 있다. 이러한 문제를 해결하기 위해, EASA와 FAA는 기존 항공기 인증 체계를 간소화 한 새로운 인증 체계 수립을 목표로 항공전자 인증표준 재편 및 간소화(RESSAC: Re-Engineering and Streamlining the Standards for Avionics Certification) 프로젝트를 2016년부터 수행하고 있다. 본 논문에서는 현재 적용되는 DO-178C 인증 프로세스를 분석하였고, DO-178C 인증 프로세스보다 과정 및 산출물을 간소화하면서도 비행 안전성을 확보 할 수 있는 새로운 RESSAC 인증 프로세스를 비교 분석하고 장점을 도출하여 제시하였다.
