摘要:

针对综合航电功能组合失效等级会随综合功能的数量增加而升级的问题，分析了典型机型综合航电系统的驻留方案，选取了适用于综合航电系统特征的分析策略，通过综合考虑共因问题、多备份系统驻留、系统设计特征、信息依赖关系等因素，实现功能组合失效影响的确认与分析，并以波音787飞机驻留方案为例证明了所提方法的正确性。

Abstract:

For the problem that the failure level of integrated avionics function combination will upgrade with the increase of the number of integrated functions,this paper analyzes the host function scheme of the integrated avionics system of the typical aircraft type,selects the proper analysis strategy that is applicable to avionics system features,realizes the confirmation and analysis of the effect of the functional combination failure by comprehensively considering the common cause problem,multiple backup system resident,system design features,information dependence and other factors.By taking the host scheme of the Boeing 787 aircraft as example,the validity of the analysis method is shown.

Key words: integrated modular avionics hosted function combinatorial failure airworthiness
