| Summary: | The paper presents major issues associated with maneuvering of the aircraft inverted flight (acrobatic). It was presented mathematical description for longitudinal balance of the airplane for inverted flight, in particular, the pitching moment coefficient plane without power for horizontal rudder (Cmbu), as well as the same force on the rudder horizontal (PHo). An analysis was conducted for gusts acting on the plane flying in an inverted position in relation to the flight envelope. It has also been analysed the horizontal tail load, acting on the inverted fly and caused by both gusts and brutal control. In conclusions, the comments on the aerodynamics of wing in flight inverted for the selected airfoil are presented. The focus is on static analysis of longitudinal balance of the airplane under normal inverted flight. Dynamic considerations, taking into account the impact of inertia on the load structure, were not carried out. Dynamic issues will be given in a separate publication.[b]Keywords[/b]: aviation, aircraft, inverted flight
