One focus of speculation is how the ACARS aboard the Boeing 777 airplane which flew MH370 was closed. From the professional point of view, this paper firstly describes the architecture and human-machine interface of Boeing 777 airplane ACARS with System modeling language ( SysML) modeling approach. Then the paper gives the in-depth analysis of the scenario of how the ACARS on MH370 was closed. At last, this paper presents the problems that exposed in this missing event and corresponding remedies.%马来西亚航空公司MH370客机失联事件一度引发媒体与公众的诸多猜测,猜测的焦点之一就是执飞的波音777飞机的飞机通信寻址与报告系统( Aircraft Communication Addressing and Reporting System,简称ACARS)功能是如何被关闭的。从专业角度出发,首先采用SysML建模的方式描述了波音777飞机ACARS系统的详细架构和人机接口,并据此深入分析了马航MH370航班失联事件中ACARS被关闭的情景。最后,提出了此次事件暴露出的现代民用飞机设计中存在的问题以及改进方法。
