America's air traffic control network is experiencing widespread disruptions, attributed to its dependence on outdated telecommunication systems, obsolete Compaq computers, and the use of eBay for replacement components. On Monday, thousands of flights across the Northeast were delayed or cancelled following a circuit breakdown at a Philadelphia air traffic facility and a fiber-optic line being severed by a construction crew near New Brunswick, New Jersey.
US Transportation Secretary Sean Duffy commented on Tuesday that the telecom architecture is 40 years old, making the system vulnerable to such failures. Officials warn that the fragility of the national air traffic control network, a result of decades of delayed modernisation and inadequate funding, will persist without a significant structural overhaul.
The Federal Aviation Administration (FAA) reportedly uses 3D printing techniques or searches eBay listings to acquire replacement components for its legacy equipment. In some cases, the agency can no longer procure spare parts. FAA Administrator Bryan Bedford stated that FAA control towers operate on individual Compaq computers, a brand that ceased hardware manufacturing in 2013.
Congress approved $12.5 billion last year to modernise national air traffic control systems. Secretary Duffy is now seeking an additional $30 billion to complete facility repairs and system upgrades.
