Chris Scott,
...but a short period of mental preparation for stick-to-surface control might be useful.
It seems useful immediately warn the crew when "UAS starts". I suspect F-GZCP was not equipped with the add on to warn on UAS like
N805NW (A330-323). I also would prefer to know (immediately) the reason for Law change, because could led PF to a more "graceful degradation situation" (a/c+PF) specially when facing "extreme conditions".
