Weight and balance

[Waynes56]

Does anybody have the cg weight and balance sheet for a yarrow arrow 2 ?

I am going to make a few assumptions here as the request is not very detailed. If my assumptions are not correct ignore what might be known information
Each aircraft has it's own W&B sheet that actually should change each time a piece of equipment is changed, or moved. The W&B sheet is a product of actual measurements and calculations on each aircraft. These calculations are checked against designed limits by the designer/kitter. A blank work sheet might look like this http://members.eaa.org/home/homebuil...ce%20Form.html
and FAA Doc H-8083-1 documents the creation of this form and graphing load limits. http://www.faa.gov/regulations_polic...-H-8083-1A.pdf

Since the Arrow 2 is a homebuilt there are usually no standard sheets like found on a certified aircraft.

Yes I believe in what your saying but every kit built aircraft I have built has a specific location for the forward and aft cg limitations given by the company ,and this is what I am looking for or am I making it harder then it is.

[Jim Heffelfinger]

Actually Wayne not harder... you want the CG limits of the Arrow. Now that is "calculations are checked against designed limits by the designer/kitter"
These limits vary with the airfoil and to a degree with the airframe moments ( correct me if I forgot something here gang) .
Now we can go out and research your inquiry.

Hi John - I have a Yarrow Arrow II that I have flown since 2000. I have done a complete restoration and flown it for 370 hours. Contact me at dennisr5@telus .net and I will send you any information I can.Dennis Richardson

I am going through this right now finishing up my condition inspection. Here is the formula that is used on this Fisher Avenger tail Dragger:


R x L=____ / w = _____ + D = CG

R= Wieght of Tail wheel
L= Distance to tail wheel from main wheel
W= Wieght of aircraft
D= Datum ....Mine is the leading edge of my wing from the main wheel center. This is my Datum.


Not sure if this is of any help.
