Parameter estimation and identification is an important part of flight mechanic. In this study the purpose is to estimate flying parameters for resistance derivation and aircraft control. At first those parameters were estimated for lateral-directional motion with which we could reach more precise results and fewer errors in time domain. In frequency domain we could reach nearly acceptable results with a specific step in special frequency band limit. In longitude motion we also had suitable responses in time domain. But we didn't have good results in frequency domain method. So to get answers from this system we analyzed motion modes and after processing frequencies to attain effective and critical signals, analysis was done in the frequency limit and therefore better results were obtained.
