Paradox of Automation
Isn't this just another (quite important) example of the Paradox of Automation?
Most aeroplanes are mostly flown by computers these days. When the autopilot fails, the human pilots can't cope. I was absolutely gobsmacked to learn the Air France flight crew who failed to recover from a stall at, what was it, 35,000 feet? -- had never practiced stall recovery in training *or even in a simulator*. Result, it fell out of the sky like a brick, killing hundreds of people in what should have been a completely survivable incident.
(You can't get a PPL without lots of practice of that situation, but then Cessnas and Pipers and whatnot spend far greater proportion of their flight time under manual control (certainly at the low end, anyway, I imagine light jets and the like have extensive automation.)
