RÉSUMÉ
This paper presents a method for the experimental determination of the longitudinal movement characteristics of the aircraft using a wind tunnel model. This method allows the determination of the neutral point and pitch stiffness. These characteristics are independent with respect to the aircraft moment of inertia. Further more, using similitude parameters and some experimental corrections one reach the rapid mode characteristics (damping and period). These characteristics are very important for the flight qualities and aircraft piloting.
