We accept the old definition of "deeptstall" for hand-flown aircrafts with impossibility to go out of that situation.
But now, the aircraft has been said to have an "apparent static longitudinal stability). That means that the "EFFECTIVE AIRCRAFT" (FCS+A/C) has a "static longitudinal stability". The minimum we have to say, is that
our EFFECTIVE AIRCRAFT has an "apparent deepstall" ! with the results BEA pointed.
Automation needs strict definitions and formulae, not litterature and psychology. Processors have algorithms no brain.
