AB Identification process of dynamic systems, such as the case of an aircraft for control tunning, is a common practice in engineering. Nowadays several flight, wind tunnel or CFD databases are used to carry it out. However, even involving a great deal of e ort both economically and temporally, the validation of the model and therefore the aplicability of the model is restricted to the area of the envelope where the flight tests have been gathered. This fi nal bachelor thesis demonstrates how decoupled simulations of flight data from complete maneuvers, both linear and nonlinear, are able to support the local identi cation of the system, a great help in local system identi cation (in the data collection area), and how they can greatly reduce the amount of required flight data. On the other hand, a new system identi cation scheme called Global System Identi cation will be tested. Aerodynamic simulations based on the Vortex Lattice Method are proposed as the fi rst approach in areas where flight data collection is not possible, allowing the extrapolation of the model to that area building correction factors. The validation of the simulations in the local area is carried out using the flight data from two di erent aircraft, and veri cation of the proposed scheme for global identi cation is performed by extrapolation in the known zone (ie, the model identi ed at a point of the envelope is corrected for another by the simulations (which in this case also exists flight data) and are veri ed with the  flight data. A first approach for modeling by extrapolation at high altitude is proposed, in the development phases of HALE platforms.
