An inquiry into the 2023 August bank holiday air traffic control (ATC) meltdown has recommended that National Air Traffic Services (Nats) gives earlier notice to airlines and airports of possible disruption.
The organisation should also review its contingency arrangements, the final report said.
More than 700,000 passengers were disrupted when flights were grounded at UK airports on August 28 last year after Nats suffered a technical glitch while processing a flight plan.
A total of 34 recommendations were made by the inquiry, which was set up by the Civil Aviation Authority (CAA) and led by Jeff Halliwell, who has served as a chief executive and non-executive director in roles across the private and public sector.
Airlines and airports should review the “adequacy” of the support available to passengers during significant disruption, particularly those who are vulnerable or travelling with children, according to the document.
Other recommendations include the CAA reviewing how Nats’ work is incentivised, and the Government considering bringing the CAA’s consumer enforcement powers into line with regulators in other sectors.
Mr Halliwell said: “The incident on 28 August 2023 represented a major failure on the part of the air traffic control system, which caused considerable distress to over 700,000 aviation passengers, and resulted in substantial costs to airlines and airports.
“Our report sets out a number of recommendations aimed at improving Nats’ operations and, even more importantly, ways in which the aviation sector as a whole should work together more closely to ensure that, if something like this does ever happen again, passengers are better looked after.”
Transport Secretary Louise Haigh said: “The Nats IT failure last year was an unprecedented event that we all hope never happens again, so I welcome the final report and its recommendations to strengthen the sector and restore passenger confidence.
“I’ve said before that I will be the passenger-in-chief and my priority is to ensure all passengers feel confident when they fly.
“That’s why my department will look to introduce reforms, when we can, to provide air travellers with the highest level of protection possible.”
CAA chief executive Rob Bishton said: “This final report gets to the heart of what went wrong in August 2023 and sets out a number of recommendations that are sector-wide in their scope.
“It is vital that we learn the lessons from any major incident such as this.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
