Center of Gravity Calculator

This Center of Gravity Calculator is used to calculate the Center of gravity of a wing as well as the Mean Aerodynamic Cord of a wing. I hope this is helpful.

Simple calculator for determining The CG distance from Leading edge at the root chords when the percent MAC is known.
Enter Root Chord (A): 
Enter Tip Chord (B): 
Enter Sweep Distance (S):
Enter Half Span (Y):
Enter %MAC Balance Point:
Sweep Distance @ MAC (C) =
Mean Aerodynamic Chord (MAC) =
MAC Distance from Root (d) =
Balance Point @ Root Chord (CG) =

 

Note:
A 25% of MAC is generally accepted as a good starting point for the CG of a conventional tailed aircraft. The normal range most often falls between 25-30% of MAC

 Use this calculator to determine percent of MAC for a given CG

 
Enter Root Cord (A): 
Enter Tip Cord (B): 
Enter Sweep Distance (S):
Enter Half Span (Y):
Enter Center of Gravity (CG):
Sweep Distance @ MAC (C) =
Mean Aerodynamic Cord (MAC) =
MAC Distance from Root (d) =
% Mean Aerodynamic Cord (%MAC) =

As I get quite a number of messages, it might take some time until you receive an answer and in some cases I get lost in the flood and you may even receive no answer at all. I apologize for this, and if you have not lost patience, you might want to send me a copy of your e-mail after a month or so.
