A Computer programme for DATCOM methods of estimation of lateral stability and control derivatives

A computer code has been developed to estimate the lateral stability and control derivatives of aircraft configuration. The code, in general, is based on USAF DATCOM methods; in the case of a few derivatives, some approximate relations are used. The code estimates nine important lateral derivatives and five control derivatives. A brief review of the methods along with the limitations of DATCOM is presented. A comparison between the results of the code with those of the worked examples of DATCOM are given for some cases. Application of the code for typical configurations is discussed
