When the stabilizer is extended and is being counteracted by elevator inputs, the forces on the control column make manually trimming stabilizers difficult or impossible. Boeing instructs that elevator input on the stick must be eased back in order to manually adjust the stabilizers.
If you object to people discussing the technical details of a plane w.r.t. the observed behaviour of that plane in an accident prior to the final report on the accident being released might I suggest....not clicking on the comment section, rather than trolling the comments on news items complaining that people are using the website for its stated purpose: to discuss the news being linked to?
And the news article we're commenting on raises the possibility that this is exactly what happened. If that doesn't make the hypothetical germane to discuss here, what can we talk about?
Agreed. Hard not to speculate though. I personally find this stuff fascinating from a technical and human factors perspective -- the deaths are tragic of course.
