摘要
飞行管理系统(FMS)是民用飞机在航线运行过程中引导飞机按照期望航迹飞行的重要系统。FMS基于机载性能数据库(PDB)构建经济的飞行剖面,并通过与显示系统、自动飞行系统、导航系统的交联完成既定的航线任务。为解决机载FMS的PDB在型号中的适航问题,保证PDB的正确性和完整性,创新地提出了部件级的数据库测试与系统级功能验证相结合的方法,以表明机载PDB满足系统的功能、性能和适航要求。研究了机载PDB在部件级对原始数据的结构完整性、格式正确性和数据准确性测试技术,以及系统级机载数据库集成功能验证技术,为民用飞机FMS PDB关键技术的自主可控提供了重要依据。
The Flight Management System(FMS)onboard civil aircraft is an important system for controlling the flight trajectory in flight operation.The FMS constructs an economical flight profile based on the airborne Performance Database(PDB)and completes the trajectory control task by interacting with the display system,the auto-flight control system and the navigation system.To solve the airworthiness issue of FMS PDB and ensure the PDB correctness and integrity,one method combining the element-level database testing with system-level functional verification is proposed innovatively to demonstrate that the airborne PDB meets the requirements on system function,performance and airworthiness.The element-level testing technology of the airborne PDB on raw data structural integrity,format correctness and data accuracy is studied,and the system-level airborne PDB integrated functional verification technology is studied,which provide support for the autonomous control of civil aircraft FMS PDB key technologies.
