That is what I did - made up the arcs in sticky back paper. Just made circles
( 2 1/4, 3 1/8 or whatever) and then can cut and overlap as necessary to
get the right size.
Have you done your weight and balance? Generally "Basic Empty Weight"
includes unusable fuel and full oil and other fluids in your case. You have to
drain it down at the carb end until it stops flowing - in the level flight attitude
(same as weighing attitude) what ever is left is your unusable - how much is
it? Honestly - who cares - make up a number if he wants to see "unusable".
It is already included in your Basic Empty weight so doesn't really matter. Of
course knowing exactly how much "usable" is a must (or should) know. I think
the "unusable" is left over from the days of using "empty weight" not "basic
empty weight".
Don't have my paper work right here but seems my unusable was about 4
gallons per side with the 120 G tanks.
Like you said - everything involving the FAA is a whole lot of effort for very
little gain <grin>.
FWIW
