Within a conventional aircraft design process, the horizontal tail and vertical are generally sized via volume coefficient methods. In this manuscript, an improved method for conceptual based on multidisciplinary optimization (MDO) approach with stability control constraints has been developed. To develop method, first, requirements have derived from regulations fundamental functionalities of p...
