Distribution of Field Loadable Software(FLS) for civil aircraft is a complex process. A variety of stakeholders are involved in the process as software suppliers, airlines and aircraft manufacturers. And to ensure security of the distribution process and integrity of the distribution data, the distribution process also involves a variety of networks, medium and methods. This paper summarizes the existing standards and specifications, and describes the loading process of FLS, which is from FLS supplier to Line Replaceable Unit(LRU), combining with the actual situation of the industry, and introduces the common methods in some processes at the same time.
