摘要
飞行管理系统(FMS)在垂直轨迹预计、垂直导航参数信息预报和垂直导引功能方面对飞行性能数据计算提出了大量需求,为了高效管理和实时使用飞行性能数据,提出了设计与创建机载性能数据库,分析了性能管理中机载性能数据库的组成、表结构、数据库文件生成与加载过程。提出采用性能数据库管理功能,进行读取、索引、查询、插值等方式处理性能数据,提高了飞行管理机载软件实时计算效率,有力地支持了机载软件工程化开发和系统验证。
Requirement of performance calculation are provided for vertical section forecasting, vertical naviga tion parameter predicting and critical directing in flight management system（FMS）. In order to manage and use flight performance data high efficiently, designing and creating airborne performance database are proposed, and furthermore, their data table structure and database composition are analyzed. In addition, the course of genera- ting and loading airborne performance database document are analyzed. It is provided that managing airborne performance database and reading, indexing, querying and inserting performance data, improving real time cal- culation efficiency of flight management airborne software. It can greatly support the engineering development of airborne software and system validation.
