Good point. But diversity still helps, lest a design flaw in the one
sensor design triggers a design flaw in the one instrument design.
Software requires diversity rather than redundancy. In practice this
means having two or three or more software packages that perform
exactly the same functions, but are written in different ways by
different development teams. It's unlikely that they will all fail in
the same way at the same time, because they are completely different
internally. This helps make the system more robust.
Something tells me that this concept never even crossed anyone's mind
at Garmin for the G1000.
