An urgent investigation is underway by the National Air Traffic Services (NATS) to determine the cause of a significant flight processing system issue. The problem led to hundreds of flights being cancelled or delayed at major airports including Heathrow, Gatwick, and Stansted. Engineers identified the fault within the flight processing system, prompting NATS to implement a fix on Tuesday afternoon. While the system is now reported to be operating normally, recovery from the backlog of flights is ongoing.
Operational Impact and Passenger Disruption
Nats boss meets minister as flight chaos hits 1,300 cancellations
Air traffic control system failure enters second day, impacting thousands of passengers across UK airports.
The computer fault meant that flights were temporarily halted from taking off from affected airports. This resulted in a shortage of parking spaces for aircraft, as planes were unable to depart. The disruption caused hundreds of cancellations and delays, with some aircraft being diverted to other airports such as Edinburgh and Cardiff. Passengers faced significant inconvenience, with the impact expected to continue for several days as individuals rebook flights or seek alternative travel arrangements.
Differing Views on the Cause
Ryanair's chief operating officer, Neal McMahon, suggested that the aviation chaos was caused by "exactly the same issue" as a problem experienced in August 2023. He stated that NATS had described the 2023 incident as a flight plan processing failure that sent the system into a loop, causing it to shut down. McMahon questioned the backup systems in place, noting that a "spurious flight plan" was reported as the cause of the recent outage.
Nats Technical Fault Disrupts Flights at Major UK Airports
Passengers faced lengthy delays and were stranded on aircraft due to an air traffic control system issue.
However, NATS chief executive Martin Rolfe indicated that the cause of the current disruption was different from previous incidents. Mr Rolfe told BBC radio that he did not believe such an incident had happened more than once in NATS's 50-year operational history, suggesting this was a new type of problem. He confirmed that a cyber attack had been ruled out as the cause of the system failure. Mr Rolfe was summoned to meet with Transport Secretary Heidi Alexander on Wednesday morning.
Mr Rolfe acknowledged that issues can occur in complex systems, but stated that all necessary personnel and partners were on site to resolve the problem as quickly and safely as possible. The ongoing disruption has led to calls for Mr Rolfe's resignation.
