We seem to have two distinct requirements for a (human) pilot.
One is a technical ability to understand information and to control the mechanics and electronics involved in a commercial flight.
The other is the ability to 'fly' which is a motor skill.
I know people who fly a Cessna who cannot use a computer and I also know wizards on the computer who would never be able to fly a Cessna.
Does a commercial pilot have to have both abilities and if so are we asking the impossible to be a driver of a modern airliner - might this be the reason for the suggested pilot errors in aircraft disasters?
