If your gonna try and use GPS in the southeastern US for the next month you’ll really just be trying. That’s according to a flight advisory issued by the FAA…See Details.
@TatWza

The Advisory warns pilots that their GPS signal “may be unreliable or unavailable” due to “GPS tests” that the Department of Defense will be conducting between January 20th and February 22nd. It notes that when the “tests” occur they will be active for 45 minutes, and be followed by 15 minutes of off time. Don’t worry about flying though, pilots will apparently be issued at least 24 hours prior to any test, but your GPS you bought from Radio Shack is probably Finished Down There. Now here is the real question, does this “Test” have anything to do with these animals dropping dead??? It”s awfully coincidental!!!
