How Is Outdated Technology Wreaking Havoc on Commercial Airlines?

If you’re lucky, you may have only heard about the countrywide suspension of air traffic that took place in January 2023. But if you were scheduled to fly during that time, you may have experienced firsthand the chaos and frustration that ensued.

The 90-minute-long suspension of air traffic issued by the Federal Aviation Administration (FAA) caused a ripple effect of widespread disruptions, with countless flights canceled or delayed, leaving passengers stranded and travel plans in disarray.

It was a situation no one wants to find themselves in, grappling with uncertainty, rearranging itineraries and dealing with the consequences of an outdated air traffic management system that couldn’t handle the demands of modern travel. The experience served as a stark reminder of the urgent need for investment in advanced technologies and infrastructure to ensure the smooth and uninterrupted flow of air traffic, sparing travelers from the frustration and inconvenience caused by such widespread disruptions.

But what exactly led to the suspension and is it something that air travelers should anticipate again in the near future?

The Notices to Air Missions (NOTAM) Database Meltdown

In the middle of a winter storm, the Notices to Air Missions (NOTAM) database faced significant issues, leading to widespread disruption and confusion in the aviation industry.

The NOTAM system serves as a crucial source of information for pilots and air traffic controllers, providing critical updates and notifications regarding potential hazards like ice on runways and closed airports and airshows nearby. The system has been around since 1947 when it was first issued by the FAA. Its current version is 30 years old, which by many accounts is considered significantly outdated and overdue for an upgrade.

Due to the many flight changes, delays and general chaos resulting from the winter storm, the NOTAM database was burdened with an influx of notifications.

This created a significant burden for pilots and air traffic controllers who had to sift through a sea of information to find the pertinent details for their flights. As a result, important updates or changes in flight conditions could have easily been missed, posing risks to the safety of passengers, aircraft crew members and the general public (hence the suspension of air traffic).

The format and organization of the NOTAMs themselves also presented challenges. The lack of standardization and consistency made it difficult for users to interpret and extract the essential information accurately. Pilots and air traffic controllers had to navigate through lengthy and complex texts, often written in technical jargon, leading to potential confusion and misinterpretation. This situation not only increased the risk of errors but also consumed valuable time and resources, causing delays and disruptions in flight operations.

Although the air traffic suspension lasted only a couple hours, its residual effect could be felt for days, resulting in backlogs in flight schedules, extensive rebooking efforts, staff shortages and frustrated passengers.

Plans to Prevent Future NOTAM Outages

In the light of the recent air traffic disruptions caused by outdated aviation technology, three U.S. Senators have introduced legislation to prevent future FAA outages.

Senators Amy Klobuchar (D-MN), Shelley Moore Capito (R-WV) and Jerry Moran (R-KS) have introduced the NOTAM Improvement Act, a groundbreaking piece of legislation aimed at enhancing the efficiency and effectiveness of the NOTAM system. The act recognizes the critical role that NOTAMs play in ensuring aviation safety and seeks to address the challenges posed by outdated technology and cumbersome processes. By promoting greater standardization, streamlining information dissemination, and leveraging modern digital platforms, the NOTAM Improvement Act is intended to prevent future disruptions caused by outdated FAA systems.

FAA has also stated plans are underway to expedite the replacement of the 30-year-old NOTAM with a brand-new system compatible with modern-day technology and aviation industry needs.

The FAA originally planned to take at least six years to replace the system; however, in response to recent events the process is to be expedited with NOTAM being fully replaced by 2025.
