Static Margin is defined as {STATIC Margin} = (NP-CG)/wing MAC*100
Online calculators use formulas that find the Neutral Point of an aircraft.
Your CG has to be ahead of that point; it is usually defined in percentage.
10 % is generally a safe starting point; personally Id recommend an online
Calculator rather that the rule of thumb 0.33 % Mac or what ever percentage
You want to use. Reasons being you is tail volume plus tail monument are a
Large contributing factor in were youre CG will go.
Hope this helps you out.
