Retired, I believe we did discuss this a couple of threads ago, and the concensus was that in Alt Law
If you use the trim wheels to move the THS, it will over ride the auto trim. Once moved, and then left alone, in Alt Law auto trim will again move it in response to the usual inputs.
Is this trained in the Sim?
Again, the point was raised in re some Unusual Attitude training scenarios, which isn't the same as an Airspeed Unreliable scenario.
I think we are in violent agreement, more or less.
