US Air Traffic Control Relies on Aging Technology and Congressional Funding
A nationwide ground stop exposed weaknesses in US air traffic control on Friday.
The United States handles more flights than any other country, but parts of its air traffic system still use technology from the 1980s.
Replacing paper flight strips with electronic ones took Canada two years, while the same change in the United States has taken more than four decades and remains unfinished.
The FAA depends on Congress to fund major upgrades, unlike systems in Canada and the European Union, where air traffic control has been privatized.
Experts say more consistent funding has helped those places improve their systems, while US equipment failures and hard-to-find spare parts have raised concerns about reliability.
Transportation Secretary Sean Duffy has asked Congress for $50 billion to modernize the system.
The United States’ air traffic control system relies on decades-old technology, including floppy disks, paper flight strips and aging computers.
A nationwide ground stop on Nov. 13 highlighted concerns about the system’s reliability and the need for modernization.
The Federal Aviation Administration says it will replace four systems dating from the 1980s by the end of 2028.
The FAA depends on Congress for funding, while aviation experts say privatized systems in Canada and the European Union have had more consistent investment.
The articles report different figures for additional funding sought by Transportation Secretary Sean Duffy: $50 billion in The New York Times and $30 billion in Folha.
- Who
- The Federal Aviation Administration and the U.S. air traffic control system.
- What
- The system uses aging technology and has faced outages, prompting calls for modernization.
- When
- A nationwide ground stop occurred on Nov. 13; the articles were published on Nov. 14 and 15, 2026.
- Where
- The United States.
- Why
- The system relies on aging infrastructure and depends on congressional funding for upgrades; the cause of the Nov. 13 outage was under investigation.
This story does not have two clearly opposing sides.
Thousands of flights in the northeastern United States were delayed or canceled after simultaneous failures at a Philadelphia control facility and an accidental fiber-optic cable cut in New Jersey.
A fiber-optic cable serving Houston’s George Bush Intercontinental Airport was cut, causing a loss of data services and a ground stop.
An FAA memo cited recent air traffic control disruptions caused by fiber-optic cable cuts and requested coordination on related projects.
The FAA announced plans to replace four systems dating from the 1980s by the end of 2028.
The FAA issued a nationwide ground stop; the cause of the outage was under investigation.

What people are saying
Canada and the European Union don’t have to worry about the public purse. They are masters of their own destiny.
We are abandoning obsolete manual processes and replacing technology that once depended on floppy disks with a modern system that allows controllers to instantly share critical flight alerts, restricted airspace schedules and pilot reports.
When it fails, we simply don’t have the redundancy we would have with a modern architecture.
