Flight simulators are nowadays used as powerful professional training tools and also as entertainment tools, and this has led to a strong rise in the development of high-fidelity simulators with a large aircraft collection. The simulator allows to reproduce the flight of a plane by noting the aerodynamic parameters characteristic for that aircraft in different flight conditions through an appropriate mathematical model of flight dynamics. In literature it is possible to find mathematical models for the aircrafts that result to be the most long-lived and the most studied, while such models are not available, for example, for military aircrafts of new generations.
