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) affect the wing lift distribution unfavorably, so the differences in overall lift and induced drag are not obvious and they depend on the details of the design. A danger associated with an insufficiently loaded canard—i.e. when the center of gravity is too far aft—is that when approaching stall, the main wing may stall first. This causes the rear of the craft to drop, deepening the stall and sometimes preventing recovery. To ensure safe pitch stability in the stall, the canard must stall first, so the wing must always stay below its maximum lift capability. Hence, the wing must be larger
