摘要
随着民用航空电子系统的逐步集成化和模块化,IMA(Integrated Modular Avionics)系统应运而生,它对民用航电系统中多个独立的应用UA(User Application)进行了综合管理和部署.在以IMA为核心的民用航电系统中,CDS(Cockpit Display System)提供了对UA界面进行显示的功能.同时CDS管理的IDU(Integrated Display Unit)显示设备提供了HMI界面,将飞行员的操作反馈给IMA上的应用.并行开发单个UA的代码和其符合ARINC 661协议的显示加载文件DF(Definition File),却分别运行在不同的目标机上(IMA和IDU),两者具有特殊的相关性和独立性.为了符合DO-178C开发和验证的要求,UA和DF交付物通过适航,对显示加载文件DF的开发和验证的过程和方式进行了研究.
With the development of integrated and modularized civil aircraft electronic system, IMA（Integrated Modular Avionics） system comes out. It manages and deploys many individual UAs（User Applications）. CDS（Cockpit Display System） which is in the civil avionics system focusing on IMA, provides the display function for UA. At the same time,CDS manages the IDUs（Integrated Display Unit） which provides the HMI for cockpit giving the feedback to UA.Developing the UA code and ARINC 661 protocol DF（Definition File） which is loaded on IDU are the responsibility of UA developers. But they are not implemented in one target PC. So, they are individual and related. In order to according with DO-178C and CAAC＇s certification, we do the research of development and verification of DF.
