A significant air traffic control failure in August 2023 has driven changes in the UK’s National Air Traffic Services (NATS), reducing homeworking and increasing on-site staffing during high-traffic periods. The disruption, triggered by a duplicate location code in the air traffic control system, led to widespread flight cancellations and delays affecting over 700,000 passengers.
The issue arose when the system mistakenly identified the code “DVL” as representing both Deauville in France and Devil’s Lake in the USA, causing a system shutdown. Efforts to resolve the fault were delayed as the lead engineer was working remotely and took more than three hours to reach NATS headquarters in Swanwick, Hampshire. Even on-site, resolving the problem required the intervention of the system’s manufacturer, Frequentis Comsoft, which restored normal operations by the afternoon.
The Civil Aviation Authority (CAA) has urged NATS to prioritize on-site engineering presence during peak travel seasons, citing an industry-wide financial impact of £75-100 million. NATS has since taken steps to increase the number of engineers available during busy periods and assured that the technical issue has been permanently resolved.
“We deeply regret the inconvenience caused by this unusual incident and have implemented measures to ensure it cannot happen again,” NATS stated.
