ACMS...In the extremely unlikely event that the remaining Pilot becomes incapacitated during the time the other is taking a comfort break the door can still be opened via key pad in good time.
Parabellum...Are you referring to the possibility of a rogue FA taking advantage of the remaining Pilot and sabotaging the aircraft? If so I have never claimed such a risk to be a threat....read my post again carefully!
My point is that a FA on the flight deck is unnecessary and does not effectively improve safety in any way.
