US air traffic control replaces outdated floppy disks with new digital systems

The Federal Aviation Administration announced on Thursday that it is phasing out legacy technology used in the United States air traffic control network. The agency plans to deploy the Enterprise Information Display System (E-IDS) to more than 400 operational control positions across 435 facilities. This modernization effort replaces four outdated systems originating from the 1980s that currently rely on floppy disks to manage essential weather and flight data.

By consolidating various data streams into a single digital platform, the E-IDS will provide controllers with faster access to the critical information required for aircraft management. This transition represents a significant shift toward a "streamlined, 21st-century system" for the agency. For technical leadership, this upgrade highlights the necessity of evaluating the long-term cost, safety, and reliability of hardware, as well as developing contingency plans for when online services fail.
