Abstract
This report deals with the equivalent system approach for the reductionof mathematicalmodels of aircraft with complex stabiJ,ityand control augmentationsystems to simple second order form. The lower order equivalent systems allow handling qualities analysis with direct reference to familiar unaugmented dynamics. A frequency responsematch of the lower order transfer functionby Rosenbrock'sdirect search method is shown to reduce longitudinaldynamics effectively. A soft ware package for model reduction is developed in FORTRAN on UNIVAC mainframe computer. .
