Fighter's Airframe is naturally unstable, and so it is coupled with FBW commands to obtain the best agility however, in override mode it is still possible to exceed a 270 deg/sec roll rate and allows the aircraft to reach 11 g (within the 12 g structural limit), instead of nine when engaged. The aircraft has a redundant fly-by-wire automatic flight control system, providing a high degree of agility and easier handling, together with stability and precise control in all situations. Multi-spar metal wing elevons have carbon-fiber skins with AG5 light alloy honeycomb cores carbon-fiber/light alloy honeycomb panel covers avionics bay most of the tailfin and all of the rudder are skinned with boron/epoxy/carbon the rudder has a light alloy honeycomb core. * First fighter jet with negative static stability. A noticeably taller tailfin allows the pilot to retain control at higher angles of attack, assisted by small strakes mounted along each air intake. * An airbrake is fitted on top and below each wing in an arrangement very similar to that of the Mirage III. The backward-retracting, steerable nose gear features dual wheels, while the main gear features single wheels and retracts inward into the wings. The landing roll was reduced by robust carbon brakes. * A runway arresting hook or fairing for a brake parachute can be fitted under the tail. * The aircraft's neutral point was moved in front of its center of gravity, giving the fighter a degree of instability that enhances maneuverability. * Parachute brake is on the tail, just above the engine exhaust.
The flight commands on the wing are: four elevons ( 15/-30°), four slats, four airbrakes (2 above and 2 below each wing.) * Low-set thin delta wing with cambered section, 58 degrees leading-edge sweep (4 at the exit wing border) and moderately blended root area-ruled two small canard wings, fixed, placed just behind the air intakes. This configuration is not ideal with regard to maneuverability, low-altitude flight, and distance required for take-off and landing, but has advantages in high-speed flight characteristics, simplicity of construction, low radar signature and internal volume. Using the concept of the delta wing interceptor seen on the Dassault Mirage III, Dassault built a new fighter jet design.
