I'm not advocating that Boeing is proposing a sensible path here; I think they're not.

But ATPs don't have any trouble evaluating "am I in potential icing conditions?" as they've been doing it for one to many thousands of hours previously.

I understand. It's just that most accidents have not just one cause but a whole chain of them. Something small happens that causes the pilots to be distracted trying to fix it, meanwhile ignoring the elephant in the room or forgetting a 'routine check'. The flight deck isn't always a relaxed place and this is when these things can get out of hand so easily.

This kind of mistake has been made so often and lives have been paid that I find it crazy that it's still being proposed.

In the "swiss cheese model" of accident causation this design is more hole than cheese.

Ironic I made this comment just before the incident with the 737 Max getting holed in flight.
