Wiggy,
i think the read and do came in way before this event. The checklist was amended at some point to make the yoke checklist non SOP. I agree with everything else’s that you’ve said. 👍
And as for the CRUX of the matter surely it’s why the capt had to reject the take off in the first place. It was a latent system failure that made it necessary to initiate the evacuation
Whichever way you look at it everyone got off safely. Good maybe, good enough definitely.
Gone are the days when an evacuation was as easy as ABCDE. A aircraft stop B brakes set C cut off fuel to engines and APU D depressurise E evacuate.
Its likely that had the crew gone against SOPs and moved the fuel control switch to cut off during the deceleration then this event would have had a better outcome. However I very much doubt any airline would advise this for v g reasons.
