At the time of writing, the facts are still emerging about why thousands of UK flights had to be cancelled or delayed on August bank holiday Monday. But the incident raises vital questions for safety professionals everywhere.

Safe skies maintained, but at what cost?

Nearly 2,000 UK flights had to be cancelled on and after what should be one of the busiest days of the year, causing delays and frustration for many tens of thousands of holidaymakers.
People are, understandably, asking why the UK’s air traffic control provider, National Air Traffic Services (NATS), was powerless to stop its systems from shutting down critical areas having received a flight plan which was “not sufficiently standard”.
This was rare, we are told, and if it did occur again the CEO of NATS, Martin Rolfe, reassures us they “can resolve it very, very quickly”. In an interview with the BBC, Mr Rolfe said the NATS system was designed to “fail safely”.
He explained that this was to make sure erroneous information could not be passed on to air traffic controllers.
The upshot was NATS had to rely on a manual system, which was slower and led to a large backlog. But it also meant that no damage was done to other data, and no accidents or incidents took place either in the air or on the ground.
On the BBC, he added: “At no point was UK airspace closed but the number of flights was significantly reduced.”
But will that satisfy the many people who had to sleep on the floor or were left out of pocket because they had to arrange last minute accommodation or alternative transport?
And will the airline industry foot the costs – which they say could run to a hundred million pounds – of reimbursing or compensating their customers?
Mike Robinson, chief executive of the British Safety Council.As a public-private partnership, partly owned by the airlines, NATS must deliver greatest efficiency while making safety its priority. This is a tension that any safety professional will recognise.
How to balance the need to ensure that no one is injured, made ill, or killed because of what you do with the need to deliver an efficient and cost-effective service?
The UK has some of the busiest skies in the world, especially in the South East and over London. And, as with all systems, we have a choice.
We can either pay large amounts up front, cater for every single possible eventuality, and provide absolute back up when something extremely rare occurs. Or we can design systems which alert us to threats and incoming risks and take immediate action to protect and safeguard us from them.
We currently await a full report from NATS on this incident, but it strikes me that in this case we have, quite rightly, chosen to go down the latter route.
If this is indeed something so rare and so unusual which, should it happen again, NATS could now deal with and resolve better, then it is probably not necessary to run an entire back up system which may itself not have been safe to operate given the erroneous flight data they had received.
Mr Rolfe explained that rejecting flight data was “nothing like throwing away spam” for air traffic controllers. He said: “If you throw away a critical piece of data you may end up – in the next 30 seconds, a minute or an hour – with something that then is not right on the screens in front of the controller.”
Clearly, not many of us operate in such a critical environment where every decision or piece of information must be handled in this way.
But I for one will sleep better knowing that the balance at NATS has not been tipped too far in the favour of ‘efficiency’ and that it still makes safety its top priority or, in its words, a “duty of care for the skies”.

In these times, how can we be safe, well and happy?
By Mike Robinson FCA on 01 July 2024
Last month, I mentioned two big moments – the General Election and the 50th anniversary of the Health and Safety at Work Act (1974) on 31 July. The lack of attention given to health, safety, or even wellbeing by most political parties in their election manifestos, while not entirely unexpected, was disappointing. And it doesn’t reflect the real concerns of workers and leaders here and around the world.
It’s time to protect all leaseholders from ruinous building safety remediation costs
By The Earl of Lytton on 28 June 2024
In my previous piece for Safety Management last summer (‘A new Building Safety Remediation Scheme would hold developers and builders to account for all fire and building safety defects in homes’) I set the scene on the unfolding world of building safety remediation and described how I was attempting to change things in the interests of consumer safety. Now with a general election called, there is an opportunity to influence the policies of a new, incoming administration.
Menopause at work: government failing to grasp benefits of providing more support to women workers
By Caroline Nokes on 01 May 2023
Many employers are waking up to the realities of menopause, and the benefits of providing a supportive environment for women at work. CIPD (Chartered Institute of Personnel and Development) research shows that 30 per cent of UK employers now have menopause policies, up from 10 per cent in 2019. But I am increasingly worried that the government has not appreciated the need to seize momentum.
