Abstract

The software installed on an aircraft is directly related to its safety. Therefore, it shall comply with the standards of the airworthiness certification to ensure safety of flight. Airborne software should be developed in accordance with the DO-178 (Software Consideration in Airborne Systems and Equipment Certification) to comply with the airworthiness certification criterion. However, the military airborne software has been developed in accordance with the DAPA weapons system software development and management manual. In this paper, we completed a questionnaire survey of software experts. We also suggest a military airborne software development/certification process based on DO-178.

항공기에 탑재되는 소프트웨어는 안전과 직결되기 때문에 안전 비행을 위해서는 감항인증 기준을 따라야만 한다. 항공기 탑재 소프트웨어는 감항인증기준에 명시된 DO-178을 따라 개발되어야 하지만 방사청 무기체계 소프트웨어 개발 및 관리 매뉴얼에 따라 개발되고 있다. 본 논문에서는 소프트웨어 전문가 설문조사를 수행하였고 DO-178을 기반으로 소프트웨어 개발 및 인증 절차를 제안하였다.
