What You'll Learn
Air traffic controller shortages
Air traffic controllers at Newark Liberty International Airport lost radio and radar contact with planes on April 28, 2025, leading to significant delays. This equipment failure exposed years of underinvestment and staffing shortages in air traffic control, despite increased demand for air travel.
The Federal Aviation Administration (FAA) has been criticized for not adequately addressing these issues. The Port Authority of New York and New Jersey, which oversees major airports in the New York City area, has urged the FAA to address ongoing staffing shortages and upgrade outdated technology.
The FAA has acknowledged the problems, with a spokesperson stating that they had at least three controllers scheduled every hour on Monday evening at a Philadelphia facility that manages Newark's air traffic. However, sources familiar with the situation claimed that the number of fully certified controllers on duty was sometimes as low as one or two.
The shortages forced the FAA to delay flights to and from Newark, with delays lasting up to nearly seven hours. United Airlines also announced that it would cut 35 flights per day from its Newark hub to ease disruptions and put more slack into the system.
The FAA has proposed replacing 618 radars and constructing six new air traffic control centers, as well as installing new fiber optic, wireless, and satellite systems. These measures aim to address the outdated equipment and chronic shortages of air traffic controllers, especially in busy airspaces like New York City.

Aging technology
The aging technology at Newark Liberty International Airport has been a significant contributing factor to the airport's recent challenges. The airport, one of the busiest in the nation, has experienced major delays and cancellations due to technological disruptions and system outages. This has resulted in a loss of trust among travellers, who are concerned about the safety of flying into Newark.
The air traffic control systems at Newark have struggled to keep up with the surging travel demand. The technology currently in use is outdated, with some equipment dating back to the late 1980s and 1990s. This includes the use of floppy disks and paper strips in the control tower, which are no longer effective in today's fast-paced aviation industry. The system outages have caused controllers' screens to go dark, resulting in a critical loss of ability to track aircraft.
The Federal Aviation Administration (FAA) has acknowledged the issues and is working to address them. They have implemented temporary measures to ensure safety, such as slowing down arrivals and departures and redirecting flight traffic to other runways. However, these measures have contributed to increased congestion and delays. The FAA is also facing criticism for not modernizing the air traffic control system sooner, as the issues with outdated infrastructure have been long-standing.
Transportation Secretary Sean Duffy has proposed a modernization plan to address the needs of the air traffic control system across the country. This includes updating telecommunications connections from copper wires to fiber-optic technology, providing greater bandwidth and speed. The FAA is also focusing on hiring more air traffic controllers and improving retention with incentive programs. However, these solutions will require significant time and investment, and it may be years before positive results are seen.
The issues at Newark highlight the urgent need for investment and modernization of airport technology. While the FAA works to implement long-term solutions, travellers can expect continued delays and disruptions at Newark Liberty International Airport and potentially other airports facing similar challenges.

Bad weather
On April 28, air traffic controllers at the Philadelphia Terminal Radar Approach Control, responsible for Newark's air traffic, lost radar and communications with planes. The communications blackout lasted anywhere from 30 to 90 seconds, an alarming duration for air travel. This incident resulted in hundreds of delays and cancellations and three dozen flight diversions.
The Federal Aviation Administration (FAA) acknowledged that their antiquated air traffic control system was affecting their workforce and pledged to improve telecommunications equipment reliability in the New York area. The FAA also slowed down departures and arrivals at Newark and deployed a backup system to alleviate disruptions.
United Airlines CEO Scott Kirby cited Newark, the airline's hub, as an example of an airport suffering from staff shortages, stating that in November, over half a million customers were delayed due to air traffic control shortfalls. In response to continued delays, United cancelled 35 round-trip flights at Newark per day.
In addition to the issues mentioned above, the closure of one of Newark's busiest runways has exacerbated the situation, leading to further delays and cancellations.

Runway construction
Newark Liberty International Airport is currently facing significant disruptions due to an ongoing runway construction project. This construction, combined with other factors, has resulted in hundreds of flight delays and cancellations, causing significant inconvenience to passengers.
The closure of one of the airport's busiest runways has severely impacted the airport's operations. With limited runway capacity, the airport's ability to handle the usual volume of traffic has been greatly reduced, leading to prolonged delays and cancellations.
The runway construction is not an isolated issue but is compounded by several other challenges. Firstly, the airport is facing a critical shortage of air traffic controllers, a problem that has plagued airports across the country for years. This shortage has been further exacerbated by recent trauma leaves among controllers, leaving the airport struggling to fill these essential roles.
Additionally, the airport has been grappling with ageing technology and equipment, resulting in multiple telecommunications and radar outages. These outages have severe implications for flight safety and punctuality, as evidenced by the radar outage on Friday morning, which caused a 90-second disruption and further contributed to the cancellations and delays.
The Federal Aviation Administration (FAA) has acknowledged the challenges facing Newark Airport and has implemented measures to mitigate the disruptions. They have slowed down departures and arrivals to ensure safety, and they are working on improving telecommunications connections and technology, including deploying backup systems.
The issues at Newark Liberty International Airport highlight the urgent need for investments in the nation's air traffic control system. A multibillion-dollar plan to upgrade the system has been proposed, aiming to provide controllers with modern technology and enhance the overall efficiency and safety of air travel.

Radar outages
On Friday morning, May 10, 2025, air traffic controllers at Newark Liberty International Airport in New Jersey lost radar access for 90 seconds. This was the second time in two weeks that such an outage had occurred, with the first taking place on April 28.
The Federal Aviation Administration (FAA) slowed down traffic at the airport following the initial outage to ensure safety, leading to hundreds of cancellations and delays. The FAA has also been dealing with multiple recent equipment and telecommunications outages. The radar outage on Friday was attributed to similar issues as the week before, with White House Press Secretary Karoline Leavitt calling it a "glitch".
The radar outages at Newark Airport are part of a larger issue affecting the nation's air traffic control system. The system has been criticized for its aging technology, with Transportation Secretary Sean Duffy announcing a multibillion-dollar plan to replace it and provide controllers with modern technology. In addition to technological issues, Newark Airport is facing staffing challenges, with a shortage of air traffic controllers. This shortage has been exacerbated by controllers taking trauma leave after the radar outages.
The combination of radar outages, staffing shortages, and other factors such as bad weather and runway construction has resulted in Newark being one of the most delay-prone airports in the nation. These issues have caused significant disruptions for passengers, with hundreds of flight delays and cancellations over several days.
