So that explains about everything. Thank you so much Capt Sly for that excellent explanation.
Must be a horrific moment for the crew hearing the engines winding up and getting faster and faster
Still not very well to understand why you would want to shut down an engine if you lost already some parts of your aircraft. I even don't do it when I have no failures at all.
