Worth noting that AF447 is an outlier on that
table in terms of full incident duration ~4mins 23 seconds which equates to 8,000 ft/min average vertical speed.
Yes, probably an outlier because AF447 came down in a deep stall, with a slower descent than for a spin , spiral dive, or the like.
It might be interesting, and possibly useful, to examine these ten accident reports and compare the situations at the start of each of these events, e.g. how many of them STARTED with a disconnect of the AP?
