RE: What is cubic wing loading????
The equation is:
Weight^2 / Area^3
Which is identical to :
Weight / Area^(3/2) = Weight / Area^1.5
^ means "raised to the power"
... so you see where the cube comes from.
And.. as Rodney stated, weight in ounces and area in square feet if you want to compare your result with the number he gave (e.g. 7 is a floater).
Perhaps someone else can chime in and explain why it is meaning full to begin with??? I've read some explanations that make sense but I've never sat down and thought it through myself.
