I would defy any computer to solve some of the complex operational problems airline crews face.
Sort this one out:
Your aircraft has a bomb on board. You divert to the nearest suitable airport. This happens to be in a country which does not welcome your problem at any cost. You try negotiating with the diversion airport for landing rights. These are refused. However, having no other option, you declare an emergency and continue for a landing. On short finals the airport authority (at night) switch off all the landing aids.
What do you do next?
I would defy any computer to resolve this type of problem. Equally, it would be highly innapropriate to give this kind of responsibility to one individual particularly if they were office based thousands of miles away.
As regards pay, in comparison to inflation, my wages have departed in a downward trend.
The single pilot 'thing' is a fanciful idea given to people who have no actual experience of operating airliners.
