I can't quite understand why the function of the two switches was changed.
Previously, if I've read it right, one turned off MCAS etc. The other one turned off manual electric trim (on the yoke)
On the MAX, both switches have the same function (in series nogal!), ALL electrical trim is turned off,
leaving only a teeny-weeny wholly manual wheel that would take something like ten
minutes of hard winding (from a difficult position) to get the stabiliser back to even neutral.
That doesn't seem very sensible. Perhaps I've got it wrong.
