ABSTRACT:
In a tail unit for a commercial aircraft having a pressurized cabin, the trimmable elevator assembly and the rudder assembly are connected to a shortened fuselage tail section. The fuselage tail section is shortened because at least the upper contour line of the tail section and the two lateral contour lines of the tail section each have at least one curvature reversal point in the outer contour. Additionally, the center box (23) of the elevator assembly passes through the tail section (16) in the area of the tail ribs (20, 22) which support the rudder assembly. This shortening of the tail section allows better utilization of the cabin space in the aircraft. Additionally, it reduces the aerodynamic drag and the total weight of the tail unit.
