An step in the path to reduce the number of pilots needed to fly commercial.
I think that airbus is aiming at allowing its new planes to be certified to be operated with just one pilot onboard. If the plane advanced autopilot allows the pilot to do the checklist by himself and in case of an emergency takes over the plane safely, it will allow the pilot to concentrate in solving the emergency (engine fire or malfunction) or if the sole pilot is disabled it’s able to safely land the airplane in the nearest airport, it will allow the airplane to be safely flown with one just pilot reducing the crew cost of operating the plane.
