Definition: In the context of aeronautical engineering, "headstalls" are parts or structures that are used to stabilize an aircraft's flight path and provide lift. These components are typically made from metal or composite materials, such as aluminum or carbon fiber, and are often integrated into the fuselage. The headstall is usually located at the top of the fuselage, behind the wingtips (the tips of the wings), and provides a stabilizing effect on the aircraft's flight path. It
