Your description kind of makes it sound like metal fatigue or corrosion or something. Looks like PIO from the article (although translated and they use the word "deterioration").

Maybe the OP and the articles author should have put a hyphen in DE-ROTATION for the reading challenged. ;)

Nose down input for derotation bad.

Slight easing of nose up back pressure is how it's normally done, there's no circumstance I'm aware of that calls for using strong nose down elevator, if you're floating that bad, time to GA.

Fair point.

When in doubt, hyphenate!

Yeah, I was really challenged on that, thanks.

If we are derotating, shouldn't we be declimbing and decruising?
