Abstract PIO (Pilot-Induced-Oscillation) is due to the mutual influence between abnormal aircraft response and pilot’s dynamic characteristic which causes the phenomenon that aircraft-pilot closed loop is instable. Therefore, airworthiness regulations (FAA25 CS25 CCAR25) 143 (a) (b) have given specific requirements for these. At the preliminary design stage of control law design, PIO tendency shall be analyzed by engineering prediction methods which will confirm whether the design of the FBW control law is suitable. In the detailed design stage, PIO tendency will be analyzed by means of simulator test with pilot in loop. During verification of worthiness compliance, evaluation criteria of PIO shall be determined according to recommended methods of AC25-7C and verify airworthiness compliance through MOC6 and MOC8. Finally, the data of flight test and/or simulator test with pilot comments show that there is no PIO tendency which meets the requirements of airworthiness regulations.
