For a wing to be stable in pitch, its CG must be forward of the
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
stability but reduces elevator authority. Recommended Static Margin:
10% for beginners, 5% for intermediate level and 1% for experts.
