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.
