This paper deals with numerical investigation about both longitudinal and lateral-directional static aerodynamic characteristics of a new twin-engine commuter aircraft with eleven seats, Tecnam P2012. Numerical analyses have been performed on complete and many partial aircraft configurations in order to evaluate the contribution of each aircraft component and to estimate their mutual interferences. The analyses have been conducted at wind tunnel Reynolds number in order to provide a validation of the numerical investigation. Finally numerical analyses have been also performed at free flight conditions, in order to have an estimation of the Reynolds number effect in especially on the aircraft base drag coefficient and on the wing span loads in both flap up and flap down conditions.
