摘　　要：本文先叙述了飞行管理计算机系统在我国目前民航飞机上的配备情况,说明了系统在飞机上的余度配置。装有两套飞行管理计算机系统的飞机上,为了协调工作,要区分为“主”和“从”系统。分析了“主”“从”系统在工作中的区别以及如何确定“主”或“从”系统的布局,最后说明在工作中如何进行故障检测,一旦某台设备失效,如何使系统重组以恢复正常工作。This paper gives a general description of the FMCS as it is installed on Chinese commercial airplanes,and explains the redundancy of the system.In the case of airplanes that have double FMCS,a distinction must be made between master and slave systems for coordinating operation.This article analyses the differences in operation between master and slave systems and explains how to determine their configuration.It also discusses how to de- tect failure and how to restore the system to normal when one equipment has failed.
