Salute!
I cannot answer to the use of WoW to provide gross weight. Great question for the Tech Log, ya think? For the big birds, I would be more concerned with the cee gee, and we saw a great example at Bagram with a 747 and the video is disturbing.
OTOH, the first Viper FSD birds had actual strain gauges in the wing roots or fuselage to limit us. That implementation did not make it to the early production planes I flew ( Bk 1,5,10 and 15), and the computers used a simple normal gee.
===============================
When you are in the first squadron of an airplane, you are a test pilot. We lowly line pilots could find things that the Edwards or Pax River golden arms and company design folks never thot of. So I did the first deadstick landing in the A-37 at Saigon Intnl( battle damage), then the first successful failed leading edge flap failure landing in the Viper. Neither one had a procedure at that time, so you just play it by ear and be ready to jump. Course, knowing your jet and using common sense helps a lot.
