To provide a characteristic figure that can be compared among various wing shapes, the mean aerodynamic chord (abbreviated MAC) is used, although it is complex to calculate. The mean aerodynamic chord is used for calculating pitching moments. [4] Standard mean chord (SMC) is defined as wing area divided by wing span: [5] Aerodynamic Center AC by a safety factor called Static Margin, which is a percentage of the MAC (Mean Aerodynamic Chord). Static Margin should be between 1% and 10% for a good stability. Low Static Margin gives less static stability but greater elevator authority, whereas a higher Static Margin results in greater static
