A method for determining lateral stability derivatives from flight measurements is obtained by arranging the lateral equations of motion in such form that information from each of the three modes of lateral motion may be utilized. This method permits determination of all the important derivatives without requiring an estimation of any of the derivatives. The results of an error analysis are given to show the effects of errors in the measured quantities on the accuracy of each stability derivative for three representative airplanes.
