Research on Scenario-Based Clustering Model and Analysis Method for Airworthiness Provisions

Airworthiness provisions are the requirements that must be followed in the development of civil aircraft. In view of the abstract characteristics of airworthiness provisions, a scenario-based clustering model and analysis method for airworthiness provision is proposed, which is applied to the identification of airworthiness requirements in the development process. Combined with the concepts of knowledge clustering and scenario, the requirements of airworthiness provisions are analyzed based on the elements of the scenario, and a provision clustering spatial model is formed. The verification results of selected CCAR 25.951 show that the proposed method is feasible in identifying the applicability of provisions for specific design features.
