The FAA Is Finally Ditching Floppy Disks in Air Traffic Control
When U.S. Transportation Secretary Sean Duffy announced on November 5 that the Federal Aviation Administration was replacing floppy disks with a modern system at air traffic control stations, the most common reaction on social media was straightforward: "Wait, someone still uses floppies?"
The answer was yes, somewhat. More than 400 FAA installations were still using data display systems dating to the 1980s that relied on floppy disks to load vital weather information and operational alerts. On November 6, the FAA confirmed that the E-IDS (Enterprise Information Display System) would be deployed to 435 sites by the end of 2028, ending a practice that had outlived the technology industry itself by decades.
The problem: every tower was a 'silo'
E-IDS replaces four legacy display systems — IDS-4, ASOS/ACE-IDS, NIDS (NAS Information Display System), and ERIDS (En Route Information Display System) — designed to operate in isolation. According to FAA Administrator Bryan Bedford, each installation functioned as an autonomous "silo" in terms of communication, with no ability to share information in real time with other facilities.
"We're moving away from outdated, manual processes and replacing technology that once relied on floppy disks with a modern system that allows controllers to instantly share critical flight alerts, restricted airspace schedules, and pilot reports across the National Airspace System," Bedford said in a statement.
The problem was not merely symbolic. Air traffic controllers across the United States had been dealing with floppy disks, decades-old Compaq computers, and replacement parts purchased on eBay to keep systems running. The floppy disk, which peaked at sales of more than 5 billion units per year in the mid-1990s, stopped being produced in large volumes after 2011.
Why did it take so long?
The United States' air traffic control infrastructure is the most complex in the world, with thousands of installations spread across the entire territory. Modernizing it is not like upgrading a personal computer — every legacy system is integrated into operational procedures, training protocols, and safety certifications.
The FAA had already begun replacing floppy disks before the recent announcement, but the scale of the challenge is enormous. Congress approved $12.5 billion in 2025 to overhaul the control system, and Secretary Duffy is seeking an additional $30 billion. Some of that funding has already yielded measurable results: 69 percent of copper wiring has been replaced, 143 towers have received Surface Awareness Initiative (SAI) systems, 26 towers have been migrated to electronic flight strips, and 226 IP voice switches have been installed.
The inflection point came after a series of incidents that exposed the risks of obsolete infrastructure. In September 2025, thousands of flights in the Northeastern United States were delayed or canceled due to system failures. In February that year, the disruption of a data link between an FAA facility and an airport resulted in the loss of data services and the imposition of a ground stop — the air traffic equivalent of a total blockade.
The commercial aviation industry pushed the agency hard. In October 2025, major U.S. airlines sent a letter to the FAA demanding "quick wins" in the $12.5 billion plan, including "ending the use of floppy disks as quickly as possible and deploying cloud-based controller displays".
The new E-IDS system
E-IDS is not just a direct replacement for floppy disks. It is an enterprise platform that consolidates essential operational information into a single digital dashboard. Instead of four separate systems that controllers had to consult individually, E-IDS merges weather alerts, NOTAMs (Notices to Airmen), PIREPs (pilot weather reports), equipment status, and outage warnings into one screen.
The FAA describes E-IDS as "a digital display board that puts important operational information in one place so controllers can quickly see updates, status information, and alerts needed to keep air traffic moving safely and efficiently."
The FAA's order (JO 7210.638), issued in September 2026, defines management responsibilities for the platform. The document emphasizes that E-IDS is "an informational aid" and should not be used for "issuance of control instructions" — meaning it complements, but does not replace, the decision-making systems of controllers.
The first five locations to receive the upgrade were announced: Atlantic City International Airport, Nashville International Airport, Greater Rochester International Airport, and the data processing hubs in Atlanta and Salt Lake City.
The global context: who still uses floppies?
While the FAA case is the most emblematic, legacy technology still lingers in critical government systems worldwide. The U.S. Air Force only eliminated 8-inch floppy disks tied to nuclear missile launch silos in 2019 — suggesting that even then, nuclear-armed silos ran software loaded by floppy disks. The Japanese government announced in 2024 that it had eliminated all systems still reliant on floppy disks, with one exception.
In the private sector, floppies are virtually nonexistent. In government, the transition is slower for reasons of certification, budget, and operational risk. The inherently critical nature of these systems — where failures can result in loss of life — creates a risk aversion that favors the status quo.
What to expect now
The completion of the E-IDS upgrade by 2028 will mark a symbolic moment: the end of a technology that dominated personal computing in the 1980s and 1990s, but survived decades in systems where innovation was considered "dangerous." The FAA had already replaced 69 percent of copper wiring, but the floppy disks were the most visible link to a system operating in the 20th century.
The question that remains is whether the modernization will be sufficient to resolve personnel problems that also plague the system. The United States faces a shortage of thousands of air traffic controllers — and new systems are only as good as the people who operate them.
