In order to provide a guide for specific investigations on WTBVFT(wind tunnel based virtual flight testing) techniques, the test system and key technologies of WTBVFT for the evaluation of FCS (flight control system) were analyzed. Based on the deficiencies of the traditional FCS evaluation methods, the advantages of WTBVFT for evaluation of FCS were analyzed. According to the common constitution of attitude control loop and guidance control loop used by FCS, the test system and working principle of WTBVFT for FCS evaluation were presented. The main differences between the WTBVFT system and the hardware-in-the-loop simulation system were analyzed. The key technologies of WTBVFT for FCS evaluation were also analyzed, including WTBVFT evaluation methods, aircraft model design technique, FCS modification technique, and model support technique.
