The non-normal operating procedures are the important basis for the operating crew to operate the airplane safely, and one of the most important factors to ensure the flight safety. The non-normal procedures involve many technical fields, so it takes long time to develop them and the development of the procedures is a complex system engineering. By analyzing the relevant international documents and reports, and according to the experience in the procedure development of the new type of airplane, the composition and function of the nonnormal operating procedures, the method of procedure confirmation, and the format of the procedures are introduced firstly. Then four stages of the non-normal operating procedures development, the contents of work at each stage and the personnel qualification are defined. Finally, the workflow of the non-normal operating procedures development is proved to be effective in operating the domestic new regional aircraft. It can be used as guidance for the non-normal operating procedures development by the civil airplane manufacturer.
