Civilian airplane is the first airplane type to fully use CCAR25 for validating the airworthiness, the flight test of control surfaces jammed situation is highly focused by CAAC. To ensure civilian airplane flight control surfaces jamming flight test successfully, surfaces jammed scheme and fight test method are studied in the paper. Three schemes of surfaces jamming are introduced and analyzed, emphasizing the principle and flight safety control scenario of the front-injected method, finally typical surfaces jammed simulation flight test method is formed . The scheme and method are validated on the civilian airplane iron bed, the results indicate that the front-injected method meets the requirements of surfaces jamming and is highly feasible.
