Abstract: Relations between the pilot model parameters and the flying qualities of an aircraft are discussed based on the Neal Smith criterion requirements.Firstly,the Neal Smith criterion requirements are described in the mathematical formulae.Secondly,the closed loop system sensitivity formulae of the frequency region related to the pilot model parameters are proved on the basis of the mathematical formulas of the Neal Smith criterion requirements in this paper.Then,using the formulas,the pilot model parameters are calculated,which can match the Neal Smith criterion requirements.The frequency characters can be calculated from the airplane model and the pilot model.The pilot rate can be inferred based on the Neal Smith criterion requirements.The method is simple and convenient to evaluate the flying qualities,and can be used to judge whether the aircraft and the pilot are matched or not.
