Overview
- The FAA warns of potential military activity and satellite navigation (GNSS) interference, citing risks at all altitudes including arrival and departure phases.
- Advisories took effect on January 16 and run through at least March 17, applying to U.S. airlines, FAA‑certified pilots and U.S.-registered civil aircraft.
- Covered areas include western Mexico and the Gulf of California, Central America and Panama, the Bogotá and Guayaquil flight information regions, and portions of the eastern Pacific.
- The FAA has not identified who is responsible for the interference or operations, and it instructs operators to use caution and report incidents to its Washington Operations Center.
- Mexico’s SICT says the alerts impose no restrictions on Mexican carriers, and aviation specialists anticipate route adjustments rather than widespread cancellations.
