Aiming to build a 6DOF flight simulation model for NASA CRM and, in the lack of lateral-directional experimental data, three different methodologies were assessed and compared. Usual semi-empirical method, vortex lattice method (XFLR5), and panel method (OpenVSP). The comparison presented is exhaustive in the aspect of isolating each component aerodynamic.
