Aircraft digital virtual flight simulation method is a simulation method based on the “human-pilot-environment” mathematical model for complete flight missions. During the preliminary design phase， this method enables initial assessment of aircraft flying qualities and airworthiness compliance， effectively addressing issues that may be difficult to modify if discovered during flight test. Furthermore， this method proves effective for the airworthiness verification of different flight states or civil aircraft developments in the same flight test course， and is increasingly being adopted in civil aircraft airworthiness verification. This paper systematically introduces the aircraft digital virtual flight simulation method， with particular emphasis on flight mission digitization and digital pilot modeling. Application examples are presented in several areas： civil aircraft configuration parameter design and operating condition determination， precise flight performance calculation， civil aircraft airworthiness compliance evaluation， military aircraft flying qualities assessment， and Category Ⅲ nonlinear PIO prediction. This paper provides a practical digital computation methodology for aircraft design， airworthiness verification， and flying qualities assessment.
