ABSTRACT	The longitudinal aerodynamic derivatives of a B-65 were estimated directly from the time histories of several maneuvers by two types of equation error method:the conventional least squares(LS)method and the total least squares(TLS)method.The estimated results were compared with those of the frequency response method.The LS and TLS methods can greatly reduce thent change and independency in explanatory variables and effective data processing to remove measurement noise are important for precise estimation.
