Milt, do Airbusses use this “upload on the tail” and the equivalent of “controlled configured vehicle”
I’m assuming not, but someone correct me please.
In any case, for a conventionally controlled aircraft, reference my first post on pitching moment, I’ll guess that the weight of the tail, or perhaps better said as the aft component of the aircraft’s weight can be used to offset the wing pitching moment. By wing pitching moment I mean of course that since the center of pressure of the underside of the wing is ahead of the center of pressure of the top side of the wing, there is a force couple, or moment trying to rotate the nose of the aircraft down. But surely then the net contribution of the tail, ie weight and aerodynamic forces, must still give a resultant down force, in order to assure stability.
