> The average of two inputs is basically garbage, it doesn't do what either of the pilots want to do and it breaks feedback for both of the pilots.

I think it's done in case one of the sticks has a bit of drift. If there was an alarm for dual input it would constantly be going off in that case.

There is an alarm on dual inputs.

Except when there's not ... In this case, it was superseded by "more pressing" alarms, namely "pull up"/"you're too low".

Yeah, that's a good point though, of course in most situations it is more urgent so this choice makes sense. BUT in this case not being aware of the dual input made the GPWS worse. So in this paricular case it was not.

Personally I would do a different type of alarm for dual input, like a big red light somewhere. Or just not allowing dual input somehow (always requiring the use of the takeover button).
