| 摘 要： | 在小型飞机航空电子系统的开发过程中,安全性评估与系统设计同步进行、相互作用。通过FHA和PSSA分析为系统设计提供了依据,为确保系统设计达到安全性保障等级需要采用容错技术。以大气数据指示功能为例,在FHA和PSSA分析的基础上提出了显示备份、冗余路径、系统重构等容错策略。

| Abstract: | During a complete development procedure of small aircraft avionics system,System safety assessments progress and interact with system design synchronously.Both FHA and PSSA provide suggestions for system level design,some fault-tolerance technologies should be adopted in order to reach the safety assurance level.Taking airdata indication function as an example,some fault-tolerance implementation methods such as display backup,redundancy paths and system reconfiguration are provided based on FHA and PSSA. |
