If my memory serves me correctly, the above requirement of wingspan ^2
divided by gross wt not to exceed 0.62 lbs is stated in the
"Certification"
limitations. It has been argued that this requirement doesn't apply to
experimental air craft. If it did, "Space Ship One" would not be
registered
with the FAA as a glider. On the other side of the coin, the Windrose
meets
the requirement; however, you find cases where it has been registered as
an
"airplane". Communications with the owners revealed that this was done to
avoid having to spend the time and money to get a glider rating.

I just notice that I have the numerator and denominator switched in the
above post.

Sorry about that!
