FAA has struggled to modernize computer, air traffic operations

WASHINGTON (Reuters) -The breakdown of a key computer system, which resulted in the suspension of U.S. flight departures on Wednesday, is not the first such issue to hinder Federal Aviation Administration (FAA) operations, and happened amid efforts to upgrade technology.

The 90-minute halt, which was caused by a problem with an alerting system that sends safety messages for pilots and others, occurred less than two weeks after a different critical air-traffic control system caused flight delays at major airports in Florida. The latest glitch disrupted more than 11,000 flights on Wednesday.

The FAA has struggled to modernize some long-standing parts of air traffic control. A 2021 Transportation Department Office of Inspection General (OIG) report repeatedly cited challenges in the FAA's multi-billion dollar Next Generation Air Transportation System (Next) infrastructure project.

The OIG said its work "has shown that FAA has struggled to integrate key NextGen technologies and capabilities due to extended program delays that caused ripple effect delays

with other programs."

In October, for example, the FAA said it was working to end a long-ridiculed, decades-old practice of air traffic controllers using paper flight strips to keep track of aircraft. But adopting the change at 49 major airports will take the FAA until late 2029.

The FAA has also been trying to modernize the Notices to Air Missions (NOTAM) system "to improve the delivery of safety critical information to aviation stakeholders," according to its website. The system provides pilots, flight crews, and other users of U.S. airspace with relevant, timely and accurate safety notices.

Last April, the FAA began investing $1 billion, out of $5 billion set aside in the infrastructure package signed into law in 2022, in repairing and replacing key equipment in the air traffic control system, including power systems, navigation and weather equipment, and radar and surveillance systems across the country.
