Aerodynamic Center
Main Wing:
R: B: T: D:
Surface Area (S): Aerodynamic Center (X):
Tail:
R: B: T: D:
Surface Area (S): Aerodynamic Center (X):
Enter values for Wing and Tail then calculate to solve for their Aerodynamic Center and surface area. Note, these values are for half of the aircraft's wing.

L:
*L is the distance between the AC of the tail and wing.
