摘　　要：本文通过研究通用飞机航电系统的基本功能需求和系统特点,总结了通用飞机航电系统的基本组成。通过对相关适航规章的分析,研究了大气、航姿、通信、导航、监视等典型功能失效状态的分类要求;针对典型的Ⅱ类涡轮螺旋桨式通用飞机,以满足功能失效概率要求为目标,采用故障树分析手段,研究了航电系统主要功能的备份需求,由此得出系统的基本逻辑架构。The basic composition of general aircraft avionics were summarized by studying the basic functional requirements and system characteristics in this paper.Classification requirements of failure conditions for typical functions such as atmosphere,attitude,communication,navigation and monitoring were studied by analyzing the relative airworthiness regulations.For typical classⅡturbine general airplane,the redundancy requirement of major functions of the avionics system were studied by fault tree analysis in order to meet the requirements of the typical functional failure probability and basic logic architecture of system was obtained.
