Default 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
Ah! I understand now!

However the above isn't true. You are mixing apples and pears. If the Weight has to be squared and the Area has to be cubed, then their relationship to each other is changed in the final result (the Area, in this case, has a greater effect on the result due to its 'boost'). You can't mix the exponents like that.

Put it this way:-

If weight = 4 and Area = 2 then :-

Weight^2 / Area^3 = 16/8 = 2

and Weight / Area^(3/2) = 2^1.5 which is about 2.8
