Aimed at the problems that both the time-consuming and laborious measures are in existence for making a measurement on the quality of the existing military airport flight area, and there is no reasonable measurement method for the rationality of the airport facilities layout, an idea of satisfaction survey is introduced, and the improved item response theory（IRT）graded response model is adopted for airport flight. The questionnaire design of the facility satisfaction degree is used to fill the blank of the facility use satisfaction questionnaires. A certain military airport is selected as a case and 96 sample databases are used as the basis to conduct unidimensional test and grade response model fitting test. A flight area facility satisfaction design model based on IRT is constructed to delete the items that did not meet the requirements and endow with a new significance to the project parameters. At the same time, the target of the survey is achieved, and a solid foundation is laid for the next extensive survey and the improvement of the survey question bank. The results show that the proposed method is scientific and feasible.
