US Flights Disrupted After Communication Failure at Air Traffic Control Centres

Air travel across the United States experienced significant disruption on Friday, November 13, after communication systems at 22 Air Route Traffic Control Centres reportedly developed problems. US Transportation Secretary Sean Duffy said the disruption affected air traffic coordination. Citing safety concerns, the Federal Aviation Administration (FAA) issued an emergency order temporarily stopping departing flights from airports across the country. Aircraft that were already airborne were allowed to continue to their destinations safely, while decisions on incoming international flights were made on a case-by-case basis. The disruption led to delays and cancellations at several airports, with thousands of flight schedules reportedly affected.

Air Route Traffic Control Centres play a key role in monitoring aircraft movements, flight paths and safe distances between planes. Communication failures made it difficult for controllers to coordinate air traffic. Reports pointed to possible problems with radio frequencies and communication equipment, but the exact cause was not immediately established. US Homeland Security Secretary Markwayne Mullin said there was no evidence of a terrorist attack or cyberattack. Officials also said there was no confirmed link between the incident and a recent Microsoft service disruption or the FAA’s SMART air traffic management system. The FAA’s investigation is expected to establish the cause. Passengers have been advised to check flight updates through airline websites or apps before travelling to airports.
