- The FAA is replacing paper flight strips and aging copper lines with the new BNATCS digital system.
- A $12.5 billion investment aims for full deployment by 2028 to modernize the National Airspace System.
- Reliable air travel assists immigrant travelers attending visa interviews, university start dates, and family reunifications.
The U.S. air traffic control system is still running on paper strips, copper lines, and aging hardware, even as the Federal Aviation Administration pushes its Brand New Air Traffic Control System (BNATCS) and the older NextGen program forward. The overhaul matters for every traveler, including immigrants whose visa interviews, family visits, work trips, and student arrivals depend on predictable flights. The FAA says it wants full BNATCS deployment by December 2028, and the work is already changing the National Airspace System (NAS) in visible ways.
Why the NAS still relies on old tools
Many towers and radar facilities still use paper flight strips. Controllers write aircraft details by hand, pass them along during shift changes, and keep them as backup when screens fail. That habit dates back to the 1940s radar era, yet it remains common because the NAS cannot afford downtime.
Old floppy disks have mostly disappeared from critical notice-to-air-mission systems, but they still appear in isolated legacy computers. Copper telephone lines and analog radios also remain in use across more than 5,000 ATC facilities. As of February 2026, roughly half of those copper connections had been upgraded to fiber, satellite, or wireless systems, but remote and Alaska facilities still depend on older lines.
The reason is scale. The NAS handles about 45,000 daily commercial flights, plus drones, space launches, and emerging urban air mobility traffic. A brief outage can ripple through the system fast. Even small technical failures can create delays far beyond the airport where the problem starts.
Why modernization moved slowly for so long
U.S. air traffic control upgrades have dragged for years because the system is huge, expensive, and hard to change without interruptions. NextGen, launched in 2007 as a $40 billion overhaul, ran into shutdowns, pandemic restrictions, contract disputes, and shifting federal priorities.
Some important upgrades did arrive. En Route Automation Modernization (ERAM) reached all 20 en route centers in 2015. Standard Terminal Automation Replacement System (STARS) went nationwide in 2021. Even so, full integration stalled because modernizing one layer often exposes another weak one.
Staffing problems made the delay worse. Controller numbers fell 6% over the past decade while air traffic rose 10%. Nineteen major facilities are understaffed by 15%. The FAA has received 200,000 applications, but only 2% graduate through the full pipeline. That process includes six months at the FAA Academy and then 2-5 years of on-the-job training.
In FY2024, the FAA hired 1,811 controllers against a target of 1,800. It still plans 8,900 hires through 2028, including 2,000 in FY2025 and 2,200 in FY2026, to produce a net gain of 2,000 controllers.
The 2026 upgrade push
Momentum changed in 2025 when Congress provided $12.5 billion through the “One Big Beautiful Bill Act” as a BNATCS down payment. The overall plan is projected at $30 billion. In December 2025, the FAA selected Peraton as the prime integrator under a contract that penalizes delays.
FAA Administrator Bryan Bedford and Deputy Administrator Chris Rocheleau said in February 2026 that the agency had acquired 600 new radars and upgraded more than one-third of its copper lines. By March, that share was nearing 50%.
BNATCS focuses on five areas: communications, surveillance, automation, facilities, and Alaska improvements. The communications piece includes 27,625 new radios, 462 digital voice switches, and 5,170 high-speed connections. Surveillance includes 612 radars and 44 airport surface radars. Facilities work covers 435 towers with new displays, 113 with simulators, and one new Air Route Traffic Control Center, the first since the 1960s. Alaska gets 110 weather stations and 64 cameras.
NextGen remains part of the picture. Its most mature tools are already in service. ADS-B surveillance is nationwide. Data Comm now operates at all 20 en route centers and supports 68 operators and about 8,000 aircraft. Terminal Flight Data Manager (TFDM) is set for 11 sites in FY2026, with 9 moving to Build 2.
The FAA also continued ERAM Enhancements 2, the NextGen Weather Processor, and Trajectory Based Operations (TBO), which creates more precise four-dimensional flight paths. These tools support drones through ACAS Xu/sXu, as well as space traffic through the Space Data Integrator, in place since 2014.

What the changes mean for flights and immigration travel
Old technology still causes delays. Manual strips slow handoffs. Copper lines limit data flow. Staffing shortages force tired controllers to work difficult shifts. During 2025, those problems contributed to wide disruptions, especially during peak travel periods and shutdown threats.
Safety has held, with zero fatalities in commercial jets since 2009, but near-misses have risen. FAA modernization aims to reduce those risks by improving conflict detection, weather updates, and runway awareness. The agency says the new system will be more data-informed and more collaboratively managed across the NAS.
For immigrants, the effect is practical and immediate. Fewer cancellations mean better odds of making a consular interview, a green card medical exam, a family reunification trip, or the first day at a new job or university. Reliable air travel also matters for international arrivals tied to H-1B work, F-1 study, and family-based immigration. VisaVerge.com reports that smoother operations are especially important for people whose plans collapse when one missed connection turns into a lost appointment.
Employers and universities also benefit. More stable flights make it easier to move staff, bring in researchers, and welcome students on time. Airlines gain a more predictable schedule. Controllers may also see relief if digital tools reduce workload and help with retention.
What still stands in the way
Big hurdles remain. The modernization bill is large, and the FAA still needs steady funding to finish the job. Cyber risks also matter, because a more digital NAS brings more connected systems. Hiring must keep pace too, or the agency could lose ground again.
There is also a global comparison. Europe’s SESAR program and Canada’s modernization efforts moved away from paper and floppy disks earlier. The United States operates a much larger airspace, so the scale is different, but the pressure is the same: build a system that can support dense traffic, drones, and space operations without breaking down.
The FAA’s Flight Plan 2026, announced by Transportation Secretary Sean Duffy and Bedford in January 2026, frames the overhaul as part of a wider push for efficiency and aviation leadership. That plan sits alongside the BNATCS timeline and the remaining NextGen work.
As those systems converge, the U.S. NAS is moving away from its World War II-era roots and toward a digital backbone built for modern traffic, including the millions of immigrants who depend on flights to reach consulates, campuses, employers, and families across the country.
