Checked maneuver is one of the longitudinal pitch maneuvers of civil aircraft, which is the critical load condition of wing and horizontal tail. For checked maneuver analysis, maneuver simulation method is mainly used domestically and internationally. The FAR and CS regulations have different requirement for the checked maneu- ver, FAR specifies the requirement of the pitch acceleration rather than the pitch operation input, while CS speci- fies the pitch operation input rather than pitch acceleration. Domestically the checked maneuver is analyzed accord- ing to the FAR regulation, there is not much research and analysis on the CS regulation. This paper conducts ma- neuver simulation research on the checked maneuver according to the CS regulation.
