Civil aircraft design must be carried out in accordance with a large amount of airworthiness requirements. Failure to capture proper requirements in early design stage may lead to unnecessary design iterations and solution alternations. Therefore, a model based method is proposed for automatically mapping proper airworthiness requirements to a current design task in the early design. It mainly includes a design task model for formal representation of different aircraft features, and an airworthiness constraint model for semantically representing airworthiness regulations. Based on the study of model mapping rules, a searching algorithm is also developed to facilitate requirements acquisition. Finally, a software tool is also implemented using the above method and tested through a case study.
