<p><em> Consider</em><em> </em><em>the</em><em> </em><em>question</em><em> </em><em>about</em><em> </em><em>influence</em><em> </em><em>of</em><em> </em><em>unsteady</em><em> </em><em>flight</em><em> </em><em>on</em><em> </em><em>the</em><em> </em><em>size</em><em> </em><em>of</em><em> </em><em>drag</em><em> </em><em>and</em><em> </em><em>lift</em><em> </em><em>coefficients</em><em> </em><em>of</em><em> </em><em>the</em><em>aerodynamic</em><em> </em><em>profile</em><em>. </em><em>Distinctive features of this investigation are obtaining data about aerodynamic drag chancing in process unsteady on high angle at attack and oscillation profile in subsonic and transonic flight. Given analysis of oscillation profile show, that dynamic loops accompany change of lift and dray force. The </em><em>researches show that it is necessary to clarity the mathematic model of the airplane flight dynamics by </em><em>introducing numbers, with take into account unsteady effects.</em><em></em></p>
