Re: Self drive
Not all the time, no. If the on-board computer simply dies, severing all fly by wire controls, the pilot is pretty much useless. Its not like there are hydrolics from the pedals in a Dreamliner cockpit to the rudder or ailerons.
If the pilot does something wrong then they are held responsible. If the plane's systems do something wrong, it is either the fault of the manufacturer, or the ground crew who were maintaining it.
