Abstract : A system of ordinary nonlinear differential equations which describes the motion of an aircraft or another flying object is investigated. Approximate methods are described of selecting the step and the method of numerical integration for the following cases: (1) the solution of a linearized system of equations taking into account the characteristics of special nonlinearities using a digital computer; (2) the solution of a linearized system of equation using a combined analog-digital set.
