Can Pilots Confuse a Runway with a Taxiway? A Real-Life Example from Turkish Airlines’ Newark Incident
Aviation is built on precision and safety, yet pilots sometimes face unexpected challenges that can lead to critical errors. One such issue is mistaking a taxiway for a runway, an error that, while rare, can have severe consequences. One notable recent example occurred with a Turkish Airlines Airbus A330-300 at Newark Liberty International Airport, where the aircraft attempted takeoff from a taxiway instead of the assigned runway.
This article delves into why these confusions happen, examines the Newark incident, and explores ways to prevent similar occurrences in the future.
Why Do Pilots Confuse Taxiways and Runways?
Runway and taxiway confusion is a complex issue influenced by several factors. Large international airports often have parallel taxiways and runways, making it easier for pilots to misidentify them, especially in low visibility conditions. Some taxiways are also wider than usual, adding to the visual similarity.
Human factors play a role as well. Fatigue, workload, and stress can reduce situational awareness, leading pilots to misinterpret their surroundings. Airport signage and lighting are critical in preventing such errors, but if they are inadequate or not properly maintained, pilots may struggle to distinguish between different surfaces.
Why Do Pilots Sometimes Confuse Runways and Taxiways?
| Factor | Description |
|---|---|
| Airport Layout and Design | Large airports with multiple parallel taxiways and runways can create confusion. Some taxiways are designed to be wider, making them visually similar to runways. |
| Weather and Visibility Conditions | Low visibility due to fog, rain, or nighttime operations can make it harder to distinguish between taxiways and runways. Wet or icy surfaces may obscure signage and lighting. |
| Human Factors and Workload | Fatigue, high workload, or stress can reduce situational awareness. Miscommunication with Air Traffic Control (ATC) may also lead to incorrect taxiing or takeoff alignment. |
| Airport Lighting and Signage | Poorly maintained or inadequate lighting can make it difficult for pilots to identify the correct taxi path. Older airports may have outdated markings that are less distinct. |
The Turkish Airlines Newark Incident
On August 6, 2021, a Turkish Airlines Airbus A330-300 (TC-JNI) operating flight TK30 from Newark to Istanbul was cleared for takeoff on Runway 22R. Due to a taxiway closure, the crew had to adjust their route to the runway. However, instead of aligning with Runway 22R, the aircraft mistakenly entered Taxiway P, which runs parallel to the runway.
The aircraft began accelerating and reached 90 knots (167 km/h) before the pilots realized their mistake. Reacting quickly, they aborted the takeoff at approximately 1,400 meters (4,600 feet) down the taxiway. While the aircraft came to a safe stop, excessive braking caused the brake discs to overheat, forcing the flight to return to the terminal. After a 1 hour and 40-minute delay, the aircraft eventually departed safely for Istanbul.
This incident underscores how even experienced pilots can make critical errors under complex operational conditions. The deviation from the standard taxi route, combined with the parallel layout of the airport, likely contributed to the mistake.
Lessons from This Incident
The Newark event highlights the need for enhanced pilot training, improved airport infrastructure, and advanced technology to minimize such risks. Pilots receive extensive training on airport layouts and situational awareness, but real-world scenarios like unexpected taxiway closures can still lead to confusion.
Technological advancements such as Runway Awareness and Advisory Systems (RAAS) and real-time airport mapping in electronic flight bags (EFBs) help pilots navigate airports more accurately. However, airport design also plays a crucial role—ensuring distinct lighting and signage between runways and taxiways can reduce errors.
Air Traffic Control (ATC) is another critical component. Surveillance systems like ASDE-X can detect aircraft misalignment before takeoff, allowing controllers to intervene promptly. Ensuring clear communication between pilots and ATC can further reduce misunderstandings.
Conclusion
The Turkish Airlines Newark incident serves as a strong reminder of the importance of vigilance in aviation operations. Although the pilots acted swiftly to prevent a disaster, the event underscores the potential dangers of runway-taxiway misidentification.
By combining pilot awareness, cutting-edge technology, and well-designed airport infrastructure, aviation safety can continue to evolve, ensuring such mistakes remain rare. With each lesson learned, the industry moves one step closer to making air travel even safer.
