In civil aircraft Flight Management System (FMS), vertical flight profile can provide all predicable information and performance parameters of flight plan in real time from takeoff to landing flight phase, such as speed, altitude and engine data. The function of vertical profile prediction and its accuracy are very important for flight path and flight performance. Its flight test is thus essential for civil aircraft airworthiness certification flight test. This paper studies deeply technical research and detailed functional characteristics on four FMS functional units and its data flow. And based on Advisory Circular(AC) documents, this paper put forward to airworthiness requirements on performance management function, performance prediction reasonableness, interface of other systems, and vertical navigation error. Four flight test procedures are then proposed and can be carried out in combination. The data results of one type aircraft are presented to demonstrate the feasibility of data analysis method. As a result, this paper can provide guidance and help for subsequent civil aircraft flight test.
