航电系统的开发既要满足系统需求、保证系统完整性、达到系统安全性目标，同时还要满足相关条例、公务要求和商业要求。而这些要求往往相互制约、相互冲突，这就使得权衡研究在航电系统的开发过程中成为一项必不可少的工作。阐明了权衡研究在航电系统开发过程中的必要陛和重要陛；然后说明了权衡研究在航电系统开发过程各阶段中的作用；接着分析了权衡研究应遵循的过程；最后，将权衡研究分析方法中的效用曲线法应用到了航电系统的网络权衡中，并提出航电系统开发过程中如何进行权衡研究的一些建议。

During the development process, avionics system shall meet the system requirements, ensure system integrity, meet system safety objective. Also, avionics system is driven by regulatory, business requirement and commercial requirement. However, these requirements are mutually effected, which resulting the trade study to be the necessary activity in the avionics system development process. This paper firstly illustrates the necessary and importance of that apply the trade study in avionics system development process. Secondly, functions that trade studies are conducted in avionics system development process are illustrated. Third, analyze the process that trade study shall follow in. Lastly, an example of trade study analysis methodology called Utility Curve applied in avionics network and the advice of trade study during avionics development process was given.
