US FAA: Error messages in the telecommunications system prompted Sunday's shift to backup

The head of US Federal Aviation Administration, said that a series?of error messages in a Telecommunications circuit? prompted the agency to switch on a 'backup -fiber line? before an outage caused thousands of flights to be snarled along the East Coast.

The FAA reported that its contractor L3Harris informed them they wanted to switch on the backup Sunday in order to begin troubleshooting the circuit at an air traffic control facility in Philadelphia before a New Jersey Transit worker?on Monday, accidentally cut the backup fibre line near New Brunswick.

L3Harris didn't immediately reply to a comment request.

Congress approved $12.5 billion for air traffic control reform last year. However, the project has taken on a new urgency after the major telecom failure that paralyzed East Coast traffic for hours.

About 9,500 US flights have been delayed or cancelled on Monday after the FAA had to halt flights at airports including New York, Philadelphia Boston and Washington for several hours.

The incoming flights were halted at the major airports the day 130 world leaders, including dozens of ministers, arrived in New York to attend the annual meeting of the United Nations General Assembly.

At an event held in Washington, FAA Administrator Bryan Bedford said to reporters that the "old system" must be discarded. When it fails, "we just don't have the redundancy we would get with a modern architecture."

Bedford stated that he believes the total cost of the upgrade to be $27 billion. Congress must approve an additional $10.5 billion to cover the cost of the project, including money from other funds.

Bedford stated that the FAA requires a modern telecommunications system to be installed on an existing network, such as Verizon or AT&T.

Bedford stated that the replacement of copper wires by fiber will be complete in September 2027, but it won't be enough to prevent future power outages.

The first phase of this project was not able to afford a new telecommunications system, "which could have been a mistake," Bedford said.
