RE: What is cubic wing loading????
It would be weight in pounds divided by area to the 1.5 power.
The 1.5 power of area is area times the square root of area. Area is in square feet. The square root of area would be in feet. Multiply these and you get feet cubed.
Dividing the 2 gives pounds per cubic foot.
If you want the conversions figured out, the formula would be:
CL = 27648*pounds/square inches/square root of sq in.
Ex: 1000 sq in & 10 lbs
CL = 27648*10/1000/sqr(1000) = 8.74 lb/cu ft
