This is news?

The President has always had broad powers in times of national emergency,
and can disable (or enable) some or all parts of the national airspace --
including GPS, ILS, VOR, and NDB. I'm sure they've got some contingencies
to shut down access to the internet, for that matter.

If there is a national emergency that requires shutting down GPS, completing
the approach may be the least of your worries.
