On April 2018, the US Federal Aviation Administration (FAA) was forced to ground all domestic US flights as a result of a widespread nationwide outage of its flight systems. The chaotic day of cancelled flights, frustrated passengers, and delayed flights had a single, disappointing cause: an antiquated technology system and a damaged database file.
The FAA is responsible for managing all air traffic within the United States, and it relies on a centralized air traffic control (ATC) system known as the National Airspace System (NAS). The NAS is a complex network of computers that support thousands of aircraft as they enter and depart US airspace. However, on the day of the incident, a damaged database file caused a bottleneck in the system, leading to system-wide slowdowns and eventually an FAA-wide outage.
When the system started to show signs of trouble, the FAA began troubleshooting the issue and identified the damaged database file as the primary culprit. To remediate the issue, a team of engineers worked to run repairs on the damaged file so the system could be reset and the flights which were cancelled due to the outage could be brought back online.
Unfortunately, the FAA’s outdated technology systems have been the source of recurrent Flight disruptions in the recent years. The organization has been criticized for relying on decades-old technology instead of investing in a modern, more reliable system.
What makes the FAA’s situation particularly concerning is that the same outdated tech is used in air traffic control systems of other countries, including the United Kingdom, Canada, and Australia. In the aftermath of the incident, these countries have been conducting thorough reviews of their own air traffic control systems in order to identify potential bottlenecks and ensure their systems are equipped to handle sudden, unexpected issues.
Overall, the FAA outage that grounded flights can be blamed on both outdated technology and a damaged database file. In order to prevent similar events in the future, the FAA must invest in modern technology and closely monitor their existing system to ensure the safety of all flights. Just as importantly, other countries must also remove legacy tech from their own air traffic control systems in order to prevent a similar incident from occurring again.
