摘要
为了满足机载软件适航认证的迫切需求,对机载软件适航认证标准进行分析研究。阐述了DO-178B的发展动因及过程,总结了随着软件开发技术的快速更新DO-178B所表现的不足。说明了对DO-178B进行更新的必要性,并将即将发布的新版本DO-178C与DO-178B进行了对比。根据对比结果重点分析了DO-178C的4个新增特性。对DO-178C所带来的影响以及未来应用进行了展望。
To meet the urgent need of airworthiness certification on airborne software, airworthiness certification standards on airborne software are analyzed. Firstly, the development motivation and process of DO-178B are provided, and the deficiencies of DO-178B in the case of the rapid update of software technology and methods are summarized. Secondly, the necessity of updating IDO-178B is pointed out, and a comparison between DO-178C which will be published in the near future and DO-178B is made. On the foundation of comparison, four new features of DO-178C are analyzed emphatically. Finally, the future prospect of the impaction and application of DO-178C are proposed.
