Interesting.

But what are the odds that all these things happened at the same time?

1. Pilot out of cockpit.
2. Pilot Sudden Incap.
3. Keypad Fails.
4. FCU fails.


Only way that smells plausible is if Germanwings (aka Lufthansa) had REALLY bad MX processes and REALLY bad safety culture.

If my ALT selector spun itself down by a large number (as opposed to 100 feet on either side of the detent), I'd have either diverted, or written it up and refused to fly it until fixed (depending on conditions at the destiantion).

Are the Euro safety agencies trying to protect their industry and corporate interests, ie scapegoat a pilot? That's more plausible I suppose.
