Re: CX Working With Airbus on Single-Pilot System for A350 With 2025 EIS

The only recent accident I can think of that occurred due to a mechanical/technical issue at cruise is AF447. Having two (and eventually 3) pilots in the cockpit didn't save that plane.

If Tesla can turn their beta-version of full-self-driving-cars loose on public roads with a single driver monitoring their automation (despite obvious safety concerns), I don't see how this is much different. Except that an A350 at cruise has a much larger safety margin than a car on a crowded highw...
