To Thomas,
In the school I learned, we got such a program
for the 206 .You have still to multiply the ´weights with the arms to get the moments if I remember right.I was thinking of something that you look at it and you know so many pasangers I can take so much bagage and so much fuel without beeing out of c of g .and not having to much weight.
To Phil,
Tell him that I'm heaving lot's of fun reading his book.The calculator in the book consists of one fixed part and one moving part.
Thank's for your contribution!
Roberto
