In order to solve the problem of low efficiency,single loading mode and high economic cost in the software loading mode of civil aircraft relying on physical media,the digital loading of Loadable Software Part(LSP)is proposed,which significantly improves the data interaction capability and operation efficiency of civil aircraft.The existing industry standards and specifications are studied,and the overall architecture of the digital loading of the loadable software is designed,after the description of the digital loading process from the software supplier to the Line Replaceable Unit(LRU),combined with the industry applications.Finally,the Architecture Tradeoff Analysis Method(ATAM)is used to analyze the digital loading architecture proposed from the perspective of redundancy,economy and safety attributes.
