FAA Alerts Airlines to Potential Military Actions and GPS Interference in Several Latin American Airspaces
The U.S. Federal Aviation Administration (FAA) has issued a formal warning to U.S. airlines to exercise extreme caution when operating over Mexico, Central America, and large areas of South America. This advisory comes amid potential military actions and GPS interference risks, which are raising the operational complexity level in the region.
The measure, communicated through Notices to Airmen (NOTAMs), introduces a new factor for strategic analysis for both airline executives and network and safety planners, within an increasingly volatile geopolitical scenario in the Western Hemisphere.
What Exactly Does the FAA Warn About and Which Regions Are Affected?
The FAA confirmed that the NOTAMs cover Mexico, Central American countries, Ecuador, Colombia, and portions of eastern Pacific airspace. The warnings are effective immediately and will have an initial duration of 60 days, a timeframe suggesting active monitoring of the situation by the U.S. aviation authority.
The agency did not impose airspace closures but did alert about two specific risks:
- Possible military activities in the region.
- Interference with GPS signals, a critical factor for modern navigation and RNAV/RNP procedures.
Geopolitical Context: The Background of the Warning
The FAA’s decision follows an escalation of tensions between the United States and several governments in the region. These tensions intensified after the Donald Trump administration executed a large-scale military deployment in the southern Caribbean, attacked Venezuela, and captured its president, Nicolas Maduro, in a direct military operation.
Trump himself has left open the possibility of new military actions, even against Colombia, further increasing regional uncertainty. This is compounded by recent statements in which he claimed that cartels control Mexico, suggesting the United States might strike ground targets to combat them.
From an aeronautical perspective, this type of rhetoric and military movements increase the risk of uncoordinated operations, flights without active transponders, and unconventional aerial activity.
Mexico’s Response and the Real Scope of the Notice
The Mexican government quickly responded to the FAA’s warning, emphasizing that it is exclusively a precaution and does not impose restrictions on Mexican airspace or its airlines. According to the relevant Ministry, the notice applies only to U.S. operators, while air operations in Mexico continue normally.
This nuance is key: this is not an FIR closure or an overflight ban, but rather a risk management directive aimed at a specific group of operators, based on military intelligence and coordination.
Recent Precedents That Explain the Caution
The FAA had already taken similar measures following the attack on Venezuela, when it restricted flights over a large part of the Caribbean, causing the cancellation of hundreds of airline operations.
FAA Administrator Bryan Bedford confirmed that during that episode, there was close coordination between the agency and the U.S. military—a relevant detail for understanding the preventive logic behind the current NOTAMs.
A specific incident reinforces the concern: last month, a JetBlue Airbus, Flight 1112 bound for New York, had to perform evasive maneuvers to avoid a mid-air collision with a U.S. Air Force tanker near the Venezuelan coast. The military aircraft did not have its transponder activated, while the A320 was flying about 40 miles (60 km) off the coast of Venezuela after taking off from Curacao.
The warning is a clear signal that the operational environment in Latin America and the Caribbean has entered a phase of greater complexity, where the line between civilian and military spheres becomes more blurred. For airlines, the message is unequivocal: planning, monitoring, and coordinating are no longer just good practice, but a strategic necessity.
