民用飞机机载设备工具鉴定评估方法研究

Research on tool qualification assessment method of airborne equipment of civil aircraft

随着民用航空领域的不断发展,机载系统及设备的复杂程度不断提高,基于软件工具的机载设备开发越来越多的出现在民用飞机研制过程中,工具的适航置信度也得到了业界更广泛的关注。基于DO-254、DO-178B/C等适航标准,对机载软件工具鉴定判定过程、判定准则、鉴定等级等开展了研究,依据工具使用场景和作用,分类提出了工具是否需要鉴定的评估方法,并通过对典型软件工具使用分析,进一步对评估方法做了说明,旨在为工具鉴定工作提供指导。

With the continuous development of civil aviation,The complexity of airborne systems and equipment continues to increase,The development of airborne equipment based on software tools is increasingly used in the development of civil aircraft,the airworthiness confidence of the tool has also received wider attention from the industry.Based on DO-254、DO-178 B/C etc.airworthiness standards,Carried out research on airborne software tool qualification judgment process,judgment criteria,qualification level,etc.According to the usage scenario and function of the tool,Classification Proposed the assessment method whether the tool needs to be qualify,and through the analysis of the typical software tools used,further explanation of the assessment method,Designed to provide guidance for tool qualification.
