The coupling of the longitudinal and lateral stability modes of an aeroplane is considered in two cases: weak coupling & strong coupling. The method presented in this paper is applied to the two flying wing designs concerning all modes in a total of eighteen flight conditions and the conclusion compares them not only from the point of view of flight stability, but also from other viewpoints.
