OK, so what. We get those every day down here in the land of the restricted zones.

Just don't do an IMC GPS approach into KCRG during the testing periods or you may end up on the trees.

As long as you don't get a GPS fault you should be fine. It is just warning you that you may get one at some point during the period.

You can always switch to VLOC mode and shoot a good old fashioned ILS!

GPS spoofing gives no GPS fault but a false position.

KCRG runway 14 has no ILS but GPS only for precision approaches (CAT I/LPV).

I'm with Jose, from experience in service to Uncle Sam. No warning guaranteed during some types of signal manipulation.

One problem with these GPS interference tests is that it affect the ADS-B functioning, so you loose ADS-B traffic detection. ATC is not affected since they are always scanning on Mode A/C/S. Unlike ADS-B that relies on a GPS signal of -130dBm that a solar flare can wipe out, Mode A/C/S has a -72dBm (transponder threshold) signal that is hard to wipe out by a solar flare or intentional jamming.
