As far as I recall, the references were to Boeing inhibiting electric trim movement of the THS in the direction that would put the aircraft further out-of-trim, at some points in the flight envelope. If it's a "fact" that electric trim can't move the stab back towards a trimmed state, either, then can we have some non-anecdotal evidence of that, please ?
