What is it about?
The paper develops a mathematical model that describes the response of an aircraft to pilot action on elevator deflection, when the effects of fuselage and wing deformations are relevant. We try to provide a simple yet representative model that can be used for teaching and preliminary design purposes.

Why is it important?
Aircraft dynamics and flight simulation have been based for almost a century on the hypothesis that an airplane is perfectly rigid. Hence 6 degrees of freedom, 3 displacement variables and 3 attitude angles, were sufficient for describing its dynamics. Many modern aircraft feature slender and deformable structural elements, which make accurate modeling much more difficult. A compromise between simulation fidelity and model complexity is thus important.
