Canards are small, wing-like structures located near the front of an aircraft, typically just ahead of the main wings. They help improve the aircraft's stability and control, especially during slow flight or maneuvers. By generating lift, canards can enhance the overall aerodynamic performance of the aircraft. In some designs, such as those seen in certain fighter jets and business jets, canards are used to complement the main wings. This configuration allows for better handling and agility, making it easier for pilots to perform complex maneuvers. Overall, canards play a crucial role in modern aviation design.
