In order to evaluate the design qualitatively and quantitatively, the design flaws are classified into two types. One type of the flaw is that affects aircraft operating, while the other affects users’ experience. Thus, analytic hierarchy process (AHP) is adopted to quantify the complex and diversity evaluation indexes. The weighted value of each index is scored by several experts, and the influence rank is formulated by weight value. At last, an evaluation checklist is worked out. In the process of filling in the checklist, the operation effects caused by design flaws and the influence ranks are clearly displayed. It would provide strong support in the tradeoff on whether design optimization is necessary.
