The construction of the technological support command of aviation equipment is a key link of the informationalization. A deep and full process analysis of the architectural framework of the aviation equipment technological support command is finished in the paper. Using the research thought of C31 for reference, a three-views architecture is put forward which can illustrate the system architecture as three-dimensional views: application, system, and technique. The research in the paper is of directive significance to the system development of the technological support command of aviation equipment both in theory and in practice.
