The flight control system is an essential part of the aircraft because it allows to maneuver and trim the plane in all flight conditions, and considering this system in the preliminary stages of a project is important, especially in the design of high-speed vehicles. Indeed, in these cases the impact of control surfaces deflections on the aerodynamic performance may be very significant, and the ability to maneuver and trim the aircraft ensuring compliance with adequate stability requirements, is generally more difficult than the case of a conventional subsonic plane, mainly because high-speed vehicles must fly in very different flight regimes through their mission profile.
