Key Notes
- The FAA plans to deploy its replacement information-display system at 435 sites by the end of 2028.
- The first five facilities include three airports and data processing hubs in Atlanta and Salt Lake City.
- E-IDS is intended to improve access to operational information, while broader modernization still faces planning challenges.
The Federal Aviation Administration has begun replacing air traffic control information systems that still rely on floppy disks, starting a rollout intended to reach 435 sites across the United States by the end of 2028.
The agency’s November 5 announcement marks a step toward retiring four systems dating to the 1980s. Their replacement, the Enterprise Information Display System, or E-IDS, brings operational information together on a common digital platform.
Where the First Upgrades Are Going
The first five facilities identified by the FAA are:
- Atlantic City International Airport
- Nashville International Airport
- Greater Rochester International Airport
- A data processing hub in Atlanta
- A data processing hub in Salt Lake City
The 435-site figure is a deployment target, rather than a count of installations already completed. The FAA says the change should speed access to essential information and reduce repairs and workarounds.
What Controllers Will See
Under the FAA’s system plan, E-IDS will serve operational positions across the air traffic network. It replaces the Information Display System 4, the ASOS Controller Equipment Information Display System, the NAS Information Display System and the En Route Information Display System.
A central aim is improving how pilot reports and aeronautical notices reach controllers. Pilot reports relay conditions encountered in flight; timely distribution helps controllers build a more current picture of the airspace they manage.
The platform also supports information exchange across the National Airspace System and management of both local and national reference material. Its planned integration with the FAA’s System Wide Information Management infrastructure is intended to connect it with other aviation information services.
Why the Older Systems Need Replacing
A September GAO review described legacy displays as difficult to maintain and cumbersome for controllers to search. It identified obsolete technology, manual updates and inefficient organization of information as problems across systems used in control towers, approach-control facilities and en route centers.
The watchdog also warned that the broader modernization effort needed stronger cost and schedule planning. It found that the FAA had not developed a reliable lifecycle cost estimate, while a second phase involving new automation systems lacked an estimated start or completion date.
What It Means for Travelers
The intended benefit is behind the scenes: controllers should be able to find and share operational information more efficiently. That is useful infrastructure work, though the announcement does not quantify a reduction in passenger delays or promise an immediate change to flight schedules.
Technology is also only one part of managing a busy network. Capacity pressures, including the scheduling dispute behind the proposed O’Hare flight cuts, remain a separate challenge. The practical milestone to watch is how the first installations progress toward the nationwide rollout.
