随着综合模块化平台在航电系统设计中的逐步普及，机载飞行管理系统在设计时应考虑分区设计因素。通过分析综合模块化平台下应用软件驻留规则，研究ARINC702A中的分区要求，提出飞行管理软件功能的分区设计方案，最后对飞行管理核心软件功能进行设计开发并给出测试验证方法，对综合模块化航电系统平台下飞行管理系统的研制具有参考意义。

With the widespread application of integrated modular architectures in avionics system,partitioning should be taken into account in the design of Flight Management System (FMS).We made ananalysis to software hosted rules under integrated architecture,studied the partition requirement of ARINC702A,and proposed a partitioning design scheme for implementing flight management functions.Finally,the core functions of FMS were developed,and a testing method was given.Our research can provide a reference for the development of FMS for integrated modular avionics system.
