If the SAT is -40, I think its too cold for any ice to actually attach itself to anything. And TAT, well that's just SAT with an adjustment for air friction so it really shouldn't matter.
As far as the 10 degrees in flight with visible moisture. Well it all depends on which temp you are talking about. And yes if the auto mode isn't kicking in, then you are the back up to flip the switch.
