基于DO-178B的大型客机机载软件符合性研究

Research on Compliance of Large Passenger Aircraft Airborne Software Based on DO-178B

随着国产化民用大型客机的研发及适航取证过程的开展,相关机载电子设备的随机适航审定工作也在持续推进,文章基于RTCA/DO-178B的目标、过程、数据三大核心要素,结合具体工程经验,针对民航客机机载软件的随机适航如何向局方表明符合性进行了研究,分别从软件计划过程、软件开发过程、软件支持过程阐述了如何满足RTCA/DO-178B符合性要求,同时对设备随机适航中局方的关注点进行了探究。

With the airworthiness certification development of domestic civil large passenger aircraft,the airworthiness certification of relevant airborne electronic equipment is also continuously promoted.This paper is based on the three core elements of RTCA/DO-178 B: goal,process and data.Combined with the specific engineering experience,this paper studies how to show the compliance to the CAAC for the airworthiness of civil aircraft onboard software,and expounds how to meet the compliance requirements of RTCA/DO-178 B from the aspects of software planning process,software development process and software support process.At the same time,the concerns of CAAC in the airworthiness of equipment are explored.
