Abstract
It 1s general practice to give the accuracy of measurement of moment and force coefficients from wind tunnel, repeatability tests and the level of uncertainties estimated from various instruments used. However, since the repeatability tests could't be carried out, a method based on the principle of propagation of errors has been used to get the accuracy in force and moment coefficients derived from errors in measurements of all independent parameters. A computer code has been written to get the level of uncertainties and percentage of ,error of various coefficients measured. ,The.listing of the code is given along with the sample output in th form of tables and graphs.
