I will read your topic in detail Mraah.... but i note some thing...
into square meters enters 3.28 by 3.28 feet .... it is 10.75 square feet by each sqaure meter.
So in example...
2. Horizonal Tail Surface Area = 51.68 sqft (15.75 m2)
The correct value must be....
2. Horizonal Tail Surface Area = 51.68 sqft (4.8 m2)
please check it.... prior to spend more job and time.
I will read your post now in detail....
