Air Traffic Control

Question: To ask His Majesty's Government what assessment they have made of interruptions to flights from several airports in the UK on 8 September due to issues with national air traffic control services.

Answer

The Government apologises to passengers across the United Kingdom who faced significant disruption as a result of the issues that impacted NATS’ operation on 8 September, resulting in delays and cancellations for a large number of passengers, as well as the disruption that it has caused for industry. Let us be clear that disruption of this kind is absolutely unacceptable.

Department for Transport officials worked closely with NATS, airports and airlines throughout the incident and recovery period to monitor impacts and provide support where necessary. The Department also provided night flight alleviations, where required, to assist airports in recovering operations.

The Secretary of State asked NATS to provide a report by Wednesday 16 September setting out the cause of the incident and the actions taken in response and has also asked the CAA to conduct an independent review into this matter immediately. The Department will continue to work closely with NATS and the Civil Aviation Authority to ensure the root cause is fully understood, lessons are identified, and appropriate steps are taken to minimise the risk of similar disruption occurring in future.
