Flight control computer is the core part of telex flight control system. It implements the control law of flight control system and it's the management unit of the whole system. System boot time is the time from booting to the entrance of application program under the air condition. According to the system require, system boot time must be within 2 seconds. This paper analysizes from the architecture model. Research all the object and process which can save system' s booting time. Implement and satisfy user requirements. At the same time, guarantee the high efficiency of operating system.%飞控计算机是电传飞控系统的核心部件,它实现飞控系统控制律计算功能,是整个系统的管理部件.系统引导时间是指空中状态下从系统上电到应用程序执行入口的时间,根据项目需求,要求引导时间在2 s以内.从飞控计算机体系结构模型出发,研究整个过程中可以节约引导时间的对象与方法,实现并满足用户需求,同时保证飞控计算机的高时效性.
