Too much to read but if all else fails turn all ADIRS off. Make direct law happen and fly it like a cessna. Stick forward and centered. Fulll power. Wings level and recover. Otherwise 80%and 2.5 nose up. Airline industry no training for UAs or chamber (depress) runs. What a joke. Don't be near rec max (coffin corner). And go around the weather. 100 mm plus who gives a ****. ATC are advisory only. Do what you need too do. No one one on the ground will save you. You are the pilot. If not, get out of the cockpit and let the big bIg boys (well trained ie Sully) do it for you. The moral of the story is don't fly into thumderstorms! Any questions?
One hint Power plus Attitude equals performance. Descend and get some CLs
