Default Weight and Balance

The local FSDO has this form they want submitted before scheduling an
inspection. It asks for (1) "Net empty C.G. range" and (2) "Loaded C.G.
limits".

Now I know that my C.G. has to fall within 15-28% of chord, and I can easily
figure that out. It works out to 77.95 to 84.84 inches aft of datum. This
is what I would think is the "Loaded C.G. limits". My empty C.G. is 78.48
which is within the limits. But what the hell is: "Net empty C.G. range"?

I think you've got it right.

have you got a removable fuel tank?
the auster has a number of empty weights.
belly tank on/off
metal/wood prop (involves additional tail ballast for the metal prop)
exhaust manifold and rear facing pipe. (involves additional tail
ballast as well)
may explain it.

That explains it! It most likely does not apply to my aircraft, since I
only have one configuration and one empty weight.
Thanks for your help.
