Some influences upon aerodynamic parameter identification of resolution, sampling rate and sample length of the flight data and dynamic characteristic of sensor are discussed. Certain lower limit of resolution and sampling rate of measurement equipment used in aerodynamic parameter identification has been detemined. The estimative results in different resolutions, sampling rate and sample length are given in the form of table. The influence of sensor time delay upon parameter estimation is stronger. But, the accuracy of parameter estimation by reduction of the sensor time constant can not be fundamentally increased.
