It also showed up this year in the SJ-100 accident as a lack of familiarity of alternate law flight control properties. In previous years, it was an ineffective response to loss of airspeed. Sometime in the next few, it will show up as something else.
That is reasonable in itself. I would add two observations:
1. This phenomenon is not limited to pilots from any particular system, on your account and supported by the UK CAA Notice
2. Irrespective of the lack of general training for Runaway Stab Trim or other unusual flight conditions, the unexpected activation of MCAS, and possible crew responses were UNTRAINABLE prior to either accident, and remain so (so far as we are aware)
You have asserted that false MCAS activation should be detected by crew as an instance of Runaway Stab Trim in a straightforward way. Others disagree.
