This paper presents the calculus of the aerodynamic coeffcients for a small aircraft in straight and level flight based on its geometric characteristic through two approximations that allows an estimation of the coeffcient for a greater range of angles of attack. In this paper we also present a control that is the result of the union of the LQR controls for the Longitudinal and Lateral-Directional models and applied it to the nonlinear complete model.
