could have braced his feet on the dashboard and yanked the yoke, or control wheel, back with all his strength.
Thanks to T.J. Crowder's comment I realize there is not only the autopilot but also a (new?) stall avoidance system installed on this new line of B737s.
Is it true that either one can be overridden by a simple application of sufficient force to the yoke? If so:
- What is the respective underlying mechanism for the systems?
- What force would be necessary, respectively?
- Are both systems designed such that they can be overridden simply by applying an unusually strong force, or would that be just a violent and "unofficial" way to control the yoke despite the systems' best efforts?1
I understand that the main flight controls of this recent incarnation of the Boeing 737, the MAX 8, are still hydraulic. Does that play a role in the "override by sheer force" possibility?
1 A design which would allow a pilot to eventually control the plane just by applying excessive and unusual force (as opposed to perform a complicated series of button presses and/or touch screen actions to disable either system) would in my opinion make a lot of sense as a "panic mode".
