This question already has an answer here:
The recent news video CNN's exclusive look inside a Boeing 737 Max simulator shows a 737 Max simulator cockpit. There are a pair of what look like large black flywheels on the console, shown spinning on their own, and then coming to rest.
What do these do, how are they used, and why is such a large, apparently very haptic device felt to provide the pilot with the best information and/or interaction?
In the real plane (not this simulator) do these connect by cables directly to moving surfaces, or are they actuated only in order to provide information in the cockpit?
