What happens if your GPS dies?

Same things that happens if my ruler ends up behind my seat, or I
make a gross error in the slide rule calculations. I fly field to
field, until I realize I am not going to make it to the next field
(kinda easy to see, the field is rising in my canbopy). I pick one of
the 3 fields I have selected as a possible landout for this scenario,
and I land in it.

That's one good solution. I currently carry charts as a backup, because
I used them for about 15 years before Loran, then GPS became options, so
I know how to use them well.

Even so, next year I plan to ditch the charts, and carry another,
independent, flight computer. It might be a Butterfly or ClearNav vario
with battery backup, an app on a smartphone/tablet thingy, or maybe a
PNA running XCsoar.
