According to years of flight test experience, a group of the civil airplane flight testers developed a flight test control system (FTCS) to conduct civil airplane flight tests. Compared with normal information management system, FTCS has more characteristics of the aviation industry itself. After experienced a number of important functions, this report assessed this system qualitatively and quantitatively. A set of assessment process was established applicable for civil airplane flight test optimization method. This process contributed to inherit the advantages for following similar systems, and correct the disadvantages of the system itself. Furthermore, this assessment can provide useful references for the development of flight test system.
