What makes you think that if there were a solar flare large enough to
"knock them all out at once" there would even be a functioning power
grid?

This appears to be a case of someone who is disliked saying that
1.1 + 1 ~= 2 and someone who should know better dragging what would be a
perfectly reasonable assertion through the mud. For the record, solar
flares can interfere with GPS signals, probably seriously:

No ****, but that's not the point.

The original statement was a solar flare large enough to "knock them all out
at once", which would take one hell of a solar flare and would likely be
a global catastrophe.

And if you are really serious about the subject, the run of the mill flare
will cause a temporary signal loss, which aviation GPS will detect, and
there is no particular reason to suspect that the current sunspot cycle
will prove to be anything other than run of the mill.

FYI the current solar flux is 74, mid-latitude A index is 26, the
mid-latitude K index is 3, and the SSN is 43.

If you want to worry about things with remote possibilities, worry about
a huge CME that hits the Earth which would fry everything electronic.
