Abstract: In order to enhance the ability of all-weather operation of civil aviation, and improve the safety level, head-up display(HUD) is developed. The application of HUD guidance function not only supports the takeoff and landing with low visibility, but also puts forward new safety requirements. In order to solve the problem of insufficient support for the verification and evaluation of HUD guidance function in the existing domestic operation certification standard system, the functional development verification and operational evaluation requirements are analyzed, and the targeted certification elements and review requirements are given, which can provide theoretical support for the airworthiness certification of HUD guidance function

Key words: head-up display, guidance, airworthiness certification, approach
