Overview
- Notices to Air Missions took effect January 16 through March 17, covering areas of Mexico, Central America, Colombia, Ecuador and adjacent eastern Pacific airspace.
- FAA cites risks from possible GPS/GNSS jamming or spoofing and military aircraft operating without transponders, affecting navigation and traffic identification at all altitudes.
- The directives apply to U.S.-registered civil aircraft, U.S. airlines and FAA‑certified pilots, and do not bind foreign carriers operating the same routes.
- U.S. airlines are adjusting routes, fuel plans and procedures as precautions, and crews are instructed to report navigation anomalies or unidentified traffic to the FAA’s Washington Operations Center.
- Mexico’s SICT says the advisory imposes no operational restrictions on Mexican aviation, and no widespread cancellations have been reported, though a December JetBlue near-miss with a U.S. tanker illustrates the risks.
