So...
Have some airlines really been training NU inputs and HITHRUST for stall recoveries when this seems to produce further (and usually unwanted) NU trimming?
Has there really been a history of excessive ND Stall recoveries creating ground proximity incidents - forcing this re-evaluatiobn of traditional stall recovery methods?
Or... has this type of recovery procedure stemmed from 'The Devil makes work for Idle Hands'..
e.g there has been no specific events creating a need for high power, NU recovereies, other than that modern fan-engined aircraft are (nominally) capable of such recoveries.
