Airbus + Cathay working on Single Pilot during Cruise with A350

[Beaker_]

I'm not sure I see much benefit. Clearly the main object is to save money, so let's apply some simple maths. I don't know exactly how much the overheads are on a single pilot, so let's base it on £100k salary + £100k training and other overheads for argument's sake:

£200k ÷ 750 hours = £266/hour
For argument's sake, let's say the aircraft has 266 passengers and they're all paying equally to the pilots salary. That's £1/hour.

So we're looking at saving £10 per passenger for a 10 hour flight.

Now when you weigh that up against the development costs and potential for unforeseen risks, issues etc. is it really worth it? Now I'm aware that every cost saving improvement is accumulative but at the thought of what sounds like reduced redundancy, saving a tenner wouldn't really cut it for me.

Edit: I didn't make it clear that the assumption would be that any savings would be passed onto the passenger. However, I suppose not all the savings need to be passed on and some of it becomes profit...
