The present study was initiated to determine whether there are basic differences in the various published methods, to point out the differences found, and to assess the relative merits of the methods for estimating the low-speed stability derivatives. The study is based on computation by various methods of the derivatives for two specific airplane configurations for which much wind-tunnel data were available. Considerable flight data also were available for one of the configurations. In addition, some other comparisons are available for flight, wind-tunnel, and theoretical derivatives. However, these references are different in scope and for other airplane configurations than those considered herein.
