Subject: How Much Load for a Load Test?

AC weight - wing weight cause wing is supported by the air in real flying
so G's will not load the spar, then multiply by G's _then_;
subtract the weight of the wing, since gravity is pulling on the wing in
the load test, so you can take that many bags bags off.
(since gravity is doing 200 pounds of the work for you)

So, I'm flying along in flight and I roll inverted and pull through to the
vertical. The ground's coming up fast and I pull to recover. The wing's
weight is towards the nose. How hard can I pull? If I designed to this
criteria I can't pull four Gs. I didn't test to four Gs. Why do you call
this a four G wing?
