I get it, and I’ve been preaching the basics as a flight instructor. The editorial emphasizes the need for pilots to stay alert to GPS interference risks, like spoofing and jamming. Bob Teter’s “Tech Talk” article, ‘GPS Jamming, Spoofing,’ is a good read on this. It points out that while GPS interference from military exercises is common in the U.S., deliberate disruptions by bad actors are rare. These issues are more frequent in places like Eastern Europe and war zones, but pilots should always be prepared and avoid over-reliance on GPS. Technical issues such as power loss, antenna disconnects, or broken wires can also cause GPS/WAAS failures. Staying ready for any GPS disruption is always a smart move.
