The U.S. Federal Aviation Administration (FAA) has issued a series of flight advisories urging airlines and pilots to exercise heightened caution when operating over parts of Mexico, Central America, South America and the adjacent eastern Pacific Ocean. 

The warnings, issued Friday as Notices to Airmen (NOTAMs), cite potential “military activities” and possible interference with satellite navigation systems as risks to civil aviation. 

According to the FAA, the advisories cover specific flight regions including airspace over Mexico, Panama, Ecuador, Colombia and broader oceanic corridors extending into the eastern Pacific. 

The agency said the alerts — effective for 60 days — are intended to ensure aircraft operators remain alert to evolving conditions that could affect flights at all altitudes, from overflight to arrival and departure phases.
