The near-miss at Austin-Bergstrom International Airport three years ago – a FedEx cargo plane almost colliding with a Southwest Airlines jet on the runway – vividly illustrates a persistent vulnerability in air travel. While thankfully averted, the incident, which occurred on a foggy winter day in February 2021, highlighted the critical demand for enhanced runway safety technology. Now, a latest system developed by Honeywell is offering a potential solution, providing pilots with direct alerts about potential collisions, adding a crucial layer of defense beyond what air traffic control can provide.
Runway incursions – any instance where an aircraft, vehicle, or person is incorrectly positioned on a runway – remain a significant concern for aviation safety. According to the Federal Aviation Administration (FAA), there were 444 runway incursions in fiscal year 2023, a slight increase from the previous year. FAA data shows that the majority of these incidents involved pilots or vehicle operators deviating from instructions, or miscommunication between pilots and air traffic controllers. The stakes are incredibly high, and even minor errors can have catastrophic consequences.
A Direct Line of Defense for Pilots
Honeywell’s new technology, dubbed Surf-A (Surface Alerts), aims to address this vulnerability by providing pilots with real-time information about the location of other aircraft and vehicles on the runway. The system utilizes data from onboard transponders – devices that broadcast an aircraft’s identity and position – to track movement on the ground. In a potential collision scenario, pilots receive immediate, clear warnings such as “traffic on runway” or “traffic behind.”
A test flight conducted last fall in Kansas City, recreating a similar scenario to the Austin near-miss on a Boeing 757, demonstrated the system’s effectiveness. Honeywell estimates that Surf-A could have given the FedEx pilots in Austin an additional 28 seconds to react, potentially preventing the incident. “It’s really important to provide pilots alerts, because seconds matter,” explains Thea Feyereisen, a distinguished technical fellow at Honeywell Aerospace. “If the alert is just in the tower, it takes a while for the controller to hear that alert. And how does that alert make it to the aircraft—you have to make sure no one else is talking on the radio at the same time. What we really desire for runway safety is multiple layers of technology defense, both in the tower as well as in the cockpit for pilots.”
Beyond Technology: A Systemic Approach to Safety
The Austin incident also revealed another layer of complexity: the airport’s previous lack of comprehensive surface detection technology. While the airport has since implemented such a system, the National Transportation Safety Board (NTSB) has consistently recommended that the FAA mandate this type of equipment – which tracks aircraft and vehicles on the ground – at all airports. The NTSB has also called for direct cockpit alerts to pilots, as Surf-A provides.
The need for a multi-faceted approach to runway safety was tragically underscored by the recent accident at LaGuardia Airport on March 22. A fire truck entered an active runway just as a Delta Air Lines plane was landing, resulting in the deaths of both pilots and injuries to dozens of passengers. The BBC reported that LaGuardia Airport does operate an Airport Surface Detection Equipment, Model X (ASDE-X) system, which uses radar and radio sensors. However, the system failed to activate due to the proximity of vehicles merging and unmerging near the runway, according to NTSB Chair Jennifer Homendy. NBC News also reported that the fire truck was not equipped with a transponder, hindering its accurate tracking.
The LaGuardia investigation is ongoing, but preliminary findings suggest that multiple factors contributed to the tragedy, including the activation of runway red lights – intended to signal an active runway – and potential communication issues between the air traffic controller and the fire truck crew. This underscores the importance of not relying on a single layer of safety, but rather implementing a comprehensive system that includes technology, clear communication protocols, and adherence to procedures.
The Role of Transponders and Surface Detection
The absence of a transponder on the fire truck at LaGuardia highlights another critical element of runway safety. Transponders allow air traffic control and other aircraft to accurately identify and track vehicles on the ground. While not mandated for all ground vehicles, their widespread adoption could significantly enhance situational awareness. The FAA is currently evaluating the potential benefits of requiring transponders on more airport vehicles.
Surf-A and similar technologies represent a significant step forward in enhancing runway safety. By providing pilots with direct alerts, these systems empower them to seize proactive measures to avoid potential collisions. However, technology alone is not a panacea. Effective implementation requires comprehensive training, clear procedures, and ongoing investment in infrastructure and personnel. The FAA is expected to provide an update on its runway safety initiatives in the coming months, outlining its plans for implementing new technologies and addressing existing vulnerabilities.
As aviation continues to evolve, prioritizing runway safety remains paramount. The lessons learned from incidents in Austin and LaGuardia serve as a stark reminder of the potential consequences of complacency. Continued innovation, coupled with a commitment to systemic improvements, will be essential to ensuring the safety of passengers and crew.
