Abstract : During the piloting of supersonic aircraft with swept wings, it is important to take into account a reduction in the overload stability margin in the transonic range of speeds at relatively small angles of attack. This is connected with the unfavorable development of flow separation on the wing and the horizontal empennage under conditions of the formation and development of supersonic zones of flow and shock waves; such a condition sometimes leads to a spontaneous abrupt rise in the overloading at these speeds.
