Summary:Pivoting coupling system of a large dihedral empennage to the tail fuselage of an aircraft, in which the empennage ( 1 ) comprises a right lateral box (la) and a left lateral box ( 1 b) arranged at a large dihedral angle in the tail fuselage ( 6 ) of the aircraft, characterised in that it comprises a horizontal central box ( 1 c) joining the lateral boxes ( 1 a, 1 b), and which comprises a rear spar ( 11 ); and means of linkage ( 2, 3, 4 ) for horizontally linking the central box ( 1 c) to a frame structure ( 7, 8, 9 ) of the tail fuselage ( 6 ) of the aircraft, which allow the empennage ( 1 ) to rotate vertically about a horizontal linkage shaft ( 5 ) between a negative maximum angle of incidence (-theta1) and a positive maximum angle of incidence (+theta2) in response to the actuation of actuator means which are connected to the empennage ( 1 ) and to a structural element of the fuselage of the aircraft.
