机载网络互连技术由传统的以ARINC 429为代表的低速、单工总线向着高速、双向、网络化方向发展。互联体系结构的变化引入了新的安全性需求，现有的适航审定技术已无法对机载高速互连网络做出评判。分析了机载高速互连网络适航的审定要求，给出了机载高速互连网络在实际审定中的审定要素和评审要求。本研究可为我国解决机载高速互连网络的适航审定问题提供理论支撑。

The airborne network interconnection technology is progressing from the low-speed, single-station bus, such as ARINC429, to high-speed, bidirectional, and networking way. The change of the network architecture introduces new safety requirements, and the existing airworthiness certification technology is unable to justify the airworthiness of the high-speed airborne network. In this paper, analysis is made to the airworthiness certification requirements of high-speed airborne interconnection network. The validation elements and review requests of the high-speed airborne interconnection network are given. This study can provide a theoretical basis for the authority to solve the certification problem of aircraft data network.
