May 1, 2022 · We call it the “mean aerodynamic chord” or “MAC” for short. The center of gravity (also called CG) is expressed in terms of a percentage along this chord line. The very frontmost point of the chord line is expressed as 0%. The rearmost point is expressed as 100%. Enter the variables at left using the same units for all entries. For an aircraft to be stable in pitch, its CG must be forward of the Neutral Point NP by a safety factor called the Static Margin, which is a percentage of the MAC (Mean Aerodynamic Chord). Static Margin should be between 5% and 15% for a good stability.to a positive (nose-up) pitching moment for positive lift when the c.g. is aft of the wing aerodynamic center. 1Also, the origin of the x-axis is taken, by convention, to be at the leading edge of the mean aerodynamic chord of the wing, and distances are normalized by the length of the wing mean aerodynamic chord. Thus, for example, weAug 15, 2023 · 1. The spanwise location of the MAC is a meaningless thing. Even the length of the MAC is fairly dubious. The thing that matters is the location of the aerodynamic center (of a wing or a wing/tail combination). The length of the MAC is used as a reference chord -- to non-dimensionalize moments. You can use any value so long as you are consistent. 2.5.3 Standard mean chord. The standard mean chord of the wing ( smc) is effectively the same as the geometric mean chord and is denoted .
