Canard (aeronautics) an aircraft designer may adopt the canard configuration to reduce the main wing loading, to better control the main wing airflow, or to increase the aircraft’s maneuverability, especially at high angles of attack or during a stall. Canard foreplanes, whether used in a canard or three-surface configuration, have important consequences on the aircraft’s longitudinal equilibrium, static and dynamic stability characteristics. The term “canard” arose from the appearance of the Santos-Dumont 14-bis of 1906, which was said to be reminiscent of a duck ("canard" in French) with its neck stretched out in flight. The Wright Brothers began experimenting with the foreplane
Canard (aeronautics) to limit drag. Such a canard airfoil has a greater airfoil camber than the wing. Another possibility is to decrease the aspect ratio of the canard, with again more lift-induced drag and possibly a higher stall angle than the wing. A design approach used by Burt Rutan is a high aspect ratio canard with higher lift coefficient (the wing loading of the canard is between 1.6 and 2 times the wing one) and a canard airfoil whose lift coefficient slope is non-linear (nearly flat) between 14° and 24°. Another stabilisation parameter is the power effect. In case of canard pusher
