The authoritative source of truth is a key component of the "Digital Engineering Strategy" as well as the core element of model-based system engineering implementation. The construction technology of an authoritative source of truth is researched, which includes defining of the concept of authoritative source of truth, establishment of the goals and principles, and design of the architecture and business processes. The supporting technologies for constructing the authoritative source of truth are also studied, and the business processes, professional models, and basic models of pre-research of civil aircraft sorted out. Finally, a pre-research case study of a civil aircraft confirms the feasibility of the technology. The authoritative source of truth can effectively improve the organization of system engineering, enhance the efficiency of collaborative design, increase the reuse of models and system design, and reduce the complexity of system engineering implementation and development costs.
