There's more, pard. Carrying the extra speed, what happens when the autoflight groks an actual velocity that is, well, excessive? BUT, if a/p is back in, the ias is low, so the nose drops, adding even more speed. Raise the nose and lose some power?? Wait, what if autoflight is gone for now, and the pilots suss extra speed? Raise the nose? And Stall? if power is left unaddressed, how quickly does even more speed build after the nose drops?? What if g prot and AOA prevent nose up?? Lower thrust and the nose drops, more speed? We don't know how long the a/p was reselected for, only that it dropped, again. If a/p is playing cutesy, and the pilots are unaware of low or high speed, they are not ahead of the a/c, even the a/c is not up with the a/c. The a/p (associated automatic) warning was INTERMITTENT. In/Out, In/Out ?
