Maybe Boeing should follow Bill Lear’s solution to a runaway trim.........a little red button that stops everything immediately.
Red buttons are too tempting to pilots. It’s documented fact.
Boeing instead has two switches right next to the trim wheel.

LOl, better to hit the red button than not flick the two little switches?
FA, where might that fact be documented?
30west - I think you will find it documented in the works of cartoonist Gary Larson. I remember a particular illustration from “The Far Side.”
BALPA says “Requiring both crew members to turn the trim wheel simultaneously in a non-normal scenario is extremely undesirable and goes against all philosophies of having one pilot fly and one run the QRH [quick reference handbook: reading out the emergency checklist]. No flight control system should require both pilots to operate it at any stage, let alone in an emergency."
The proposed AD says, “A two-pilot effort may be used to correct an out of trim condition.”
I respect BALPA, but I can’t see how they arrived at the word “requiring” in their statement regarding the proposed AD.
