民机 CNS 系统适航验证方法分析与实践

摘要

适航是我国民机 CNS(Communication,Navigation and Surveillance)系统发展的关键。以适航为目标,首先分析并确定了 CNS 系统验证的需求,然后通过分析适航标准提出了满足适航要求的CNS 系统验证方法,即按照验证方法、验证级别、测试环境方案以及验证实施追溯过程为线进行验证分析。该方法还可适用于民机其他航电系统。%Airworthiness is the key to the development of China's civil aircraft CNS(Communication,Navi-gation and Surveillance) system. This paper analyzes and determines airworthiness requirements and verifi-cation requirements of CNS system,and presents the verification method of CNS system according to airwor-thiness standards,that is performing verification by flowing the verification methods,verification levels,test bench and trace process. The method proposed in this paper can also be applied in other civil aircraft avi-onics systems.
