• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

When measuring the moment for the pilot and passenger seats, what specific spot is used for the measurement? My question relates to where is the center of gravity for a person sitting in the aircraft seat. With the back slightly reclined and the legs and feet forward, what specific location of the body do you use for the aircraft CG calculations. Do you use the bottom rear tube of the seat bottom, the center of the seat, or?
I have been flying my Acro Sport II for 24 years and almost 600 hours, but I have never asked another Acro Sport II owner exactly how they did their CG calculations for changes to the CG with or without a passenger or for heavier pilots or passengers.
Thoughts?
Steve
