Thank you, TheShadow, very informative. I guess I come from a generation when "having to manually hand-fly an aircraft" was the preferred option.
If there's to be any real progress, I guess we need to examine what training led to the 'human factors' error they made. From my humble flight safety background, it usually turns out to be human factors rather than pilot error.
Next time I fly the pond, I'm tempted to fly it myself in a puddlejumper(again).
p.s. there will only ever be one 'procedure' for everything; it's called "airmanship".
