ABSTRACT:
In an aircraft exhibiting an undesirable nose-down pitching moment due to a rearward shift of the wing lift acting aft of the characteristic pitch axis of the aircraft as speed increases in a certain speed regime, the vertical member of the tail section is configured to develop an increasing drag. The increasing tail member drag acts in elevation above the horizontal plane that contains the pitch axis so as to develop a counteracting nose-up pitching moment that mitigates the unwanted nose-down pitching component associated with changing wing lift characteristics.
