I'm still struggling with the though that a grossly mis-trimmed stab on an NG cannot be recovered by either electric trim or by the strength of 1 or even 2 pilots cranking the wheels when the aircraft is at certain parts of the flight envelope.
As covered by others above, it seems bizarre to rely on having the airspace and time available to perform an acceleration or deceleration to a trimmable speed and/or perform a manoeuvre in the opposite sense to what you are trying to achieve in order to put the stab in a safe position.
Hopefully Boeing can enlighten us as to which parts of the performance envelop allow for PF solo cranking, PM dedicated cranking, both pilots cranking or just plain impossible to crank the wheel due to aerodynamic load. The NG is still flying and I am sure the AOCs would like to know, even if the FAA is asleep at the wheel at a benign 1G.
