This paper presents the results of long time scientific activities related to two light planes: high wing P92J and low wing P96 aircraft. Both aircraft are built by the TECNAM industry. The investigations have regarded numerical calculations of aerodynamic characteristics (global coefficients for airfoils, wings, total aeroplane, etc.) followed by the simulation of static and dynamic behaviour of the aircraft. Then wind tunnel tests on body, wing-body and complete aircraft models have been done and a complete flight test campaign for both P92J and P96 aircraft has been performed. As far as it concerns numerical calculations, this paper will present results obtained using three in-house developed codes, namely TBVOR (2D viscous analysis), AEREO (complete aircraft aerodynamics) and DYNASIM (interactive aircraft motion and dynamic behaviour prediction for an user specified control law via mouse or for an imposed air disturbances). The flight tests have been performed using an in-house developed apparatus which is easy to use and to install and which stores all signals taken by different mounted devices (accelerometer, angle measurements, etc.) The results presented in the paper will regard comparison between numerical, wind tunnel and flight test for the P92J high wing aeroplane while for the P96 aircraft only numerical and wind tunnel test will be discussed.
