In terms of basic management rules and parameters, the development of all kinds of aviation products is almost the same, but because of the different markets and customers, civil aviation products development in the aspect of system construction and technical coverage has its own characteristics. Especially ,the aviation regulation requirements and environment of customers are different,so that the development of civil aviation products must take more concentration on the technical and operation support in the whole life cycle of the products in the early stage of the development. That would lead in developing the differentiation of the construction of system and technical ability of product development phase . Thus, to recognize and grape those differences early is the need for the healthy development of civil aviation products industry.
