Wing configurations refer to the arrangement and shape of wings on an aircraft, which significantly influence its performance and stability. Common types include high-wing, low-wing, and mid-wing designs. High-wing aircraft have wings mounted above the fuselage, providing better visibility and stability, while low-wing designs offer improved aerodynamics and easier ground handling. Another important aspect of wing configurations is the wing shape, which can be straight, swept, or delta. Straight wings are typically found on smaller aircraft, while swept wings are common in faster jets, as they reduce drag at high speeds. Delta wings, characterized by their triangular shape, are often used in supersonic aircraft for enhanced performance.
