Fair enough. The “hidden” aspect is what I was alluding to…ie, control that exists but isn’t apparent to the pilots (and worse, intermittent). In the human factors world, it was more complex than the pilots assumed, but you’re right that it’s probably not the best description.

(As an aside, the hazard being mitigated, ie stall, has little bearing on whether or not it’s autonomous or complex, although it does impact whether its safety critical)
