What does the Mean Aerodynamic Chord (MAC) represent in aircraft design?

The Mean Aerodynamic Chord (MAC) represents the average distance from the leading edge to the trailing edge of a wing, which is crucial in determining the aerodynamic characteristics of the wing. In aircraft design, MAC is used to simplify the analysis of the aerodynamic behavior by treating the wing as if it were a single geometric shape. It serves as a reference point for calculating the center of lift and is essential for stability and control considerations. The MAC helps in scaling and comparing wings of different designs and aspect ratios while providing a basis for understanding lift and drag characteristics throughout various flight conditions.
