A preliminary technical report by the National Air Traffic Service (Nats) claimed the issue was caused by a data anomaly that forced its system to stop processing flight plans. The system was closed to maintain safety and required manual operation to continue service.
The CAA said it would now independently review the issues around the system failure and how Nats responded to the incident – with the threat of “appropriate” action should the organisation be found to have breached its statutory and licensing obligations.
