A method has been derived by which a boundary can be obtained that defines a region in which there exists a satisfactory relationship between the period and damping of the lateral oscillatory mode of motion, according to any given criterion for this relationship. In addition, a method is discussed by which curves representing a constant rate of spiral divergence may be constructed. The methods presented are applicable as well to the analysis of longitudinal stability. A method for evaluating the roots of a quartic equation is also discussed.

Application of the method of characteristics to the linearized three-dimensional equation results in a relatively simple system of difference equations that can be used to compute the supersonic flow past boundaries for which no other linearized solutions are available.
