AF447 is an accident that I have spent a lot of time reading and thinking about. I (kind of) disagree with your above statement. If I recall correctly (without unwinding the whole sequence of...

Found this simulator video of a 737 trim runaway, what is the alarm at 2:57? And are the switches to turn off the autotrim still there in the newer 737s, and would they disable the MCAS?

Apart from the discussion if a ND trim automatism on a detected impeding stall (false or not) is a good choice, I think that any autonomous, severe intervention into the flight controls should always...

A layman's question: As this MCAS trim behaviour seems to be designed as an emergency measure in lieu of a stick pusher, is there any information feedback to the pilots that it's been activated?...

Hm, I think that is only partially true. Rigid procedures & training aim to make pilot behaviour both predictable and, consequently, identical.

If I remember correctly, in the Airbus the trim wheel does not make the 'clack-clack-clack' sound that other aircraft do. Another example of technology that seems to be designed to withhold...

Indeed - and it even only partly achieves redundancy for intrinsic failures, since design/manufacture faults are likely to be present in all sensors if they are from the same manufacturer & type and...
