THE UK’S NATIONAL Air Traffic Service (NATS) has said that the air traffic control failure it experienced yesterday was caused by flight data it received, with both primary and back-up systems responding by suspending automatic processing, chief executive Martin Rolfe said.
Thousands of holidaymakers had their flights delayed or cancelled yesterday after the technical fault meant flight plans had to be input manually by controllers
The fault was remedied at around 3.15pm yesterday afternoon, but the impact on airlines was still being felt today.
Analysis of flight data websites by the PA news agency shows at least 281 flights – including departures and arrivals – were cancelled today at the UK’s six busiest airports.
In a statement this evening, Rolfe said: “Very occasionally technical issues occur that are complex and take longer to resolve. In the event of such an issue our systems are designed to isolate the problem and prioritise continued safe air traffic control.
“This is what happened yesterday. At no point was UK airspace closed but the number of flights was significantly reduced.”
He said an initial investigation into the problem show it relates to some of the flight data NATS received.
The company’s primary and back-up systems responded to the data by “suspending automatic processing to ensure that no incorrect safety-related information could be presented to an air traffic controller or impact the rest of the air traffic system”.
Rolfe said there are no indications that the fault was a cyber-attack.
“We have well established procedures, overseen by the CAA, to investigate incidents. We are already working closely with them to provide a preliminary report to the Secretary of State for Transport on Monday.”
He said the conclusions of the report will be made public and apologised for the fault.
“I would like to reassure everyone that since yesterday afternoon all of our systems have been running normally to support airline and airport operations as they recover from this incident.”
Earlier today, Ryanair boss Michael O’Leary slammed NATS for the “unacceptable” disruption caused over the past two days following a technical fault.
In a video message today, O’Leary described yesterday as “a very difficult day” with 250 flights cancelled, while a further 70 flights were axed today.
Speaking from the airline’s operations centre at Dublin Airport, he said: “I’m sad to report that we had to cancel about 250 flights affecting the flights of about 40,000 passengers because of long delays to flight plans, crews running out of hours.
“Last night we had 20 aircraft that couldn’t get back to their home bases so they’re out of place for today.
“Today, unfortunately, it looks like we’re going to cancel about another 70 flights.

“That’s a very small number out of the 3,200 flights we’re planning but that doesn’t mean we’re not doing everything we possibly can to try to minimise the disruption for our passengers and their families.”
The Ryanair boss said the airline had been in contact with NATS about the issue.
“We still haven’t had an explanation from them (about) what exactly caused this failure yesterday and where were their back-up systems,” he said.
It’s not acceptable that UK NATS simply allow their computer systems to be taken down and everybody’s flights get cancelled.
He added: “We hope by the end of today, Tuesday, that from tomorrow we’ll be running a normal operation.”
In a statement this morning, Kevin Cullinane, group head of communications at daa, the operator of Dublin and Cork airports, said further flights were impacted by delays or cancellations today.
“The teams at Dublin and Cork airports are working hard to support our airline partners and to ensure passengers impacted by UK air traffic control issues resume their travel plans as quickly and as safely as possible,” he said.
Passengers intending to fly from Dublin Airport today are advised to check the status of their flight with their airline before travelling to the airport, while passengers needing to re-book flights have been encouraged to do so through their airline’s app or website.
Dublin Airport has waived any car parking fees for customers returning to the airport as a result of delays.
For any car park customers delayed as a result of the ATC issues in the UK, we are waiving any additional parking fees they may have incurred. Impacted passengers should speak with a member of staff on the ground or use the intercom facility when exiting their car park. 🚗 (3/3)

A spokesperson for Aer Lingus stated today that it continues to face “unavoidable cancellations and delays”.
“We are doing everything possible to minimise any further disruption to our customers and we apologise to all those impacted for the inconvenience caused, which is due to circumstances outside of our control.”
Aviation analytics company Cirium said across all UK airports yesterday, 790 departures and 785 arrivals were cancelled. That was equivalent to around 27% of planned flights.
There is speculation the fault was caused by a French airline submitting a flight plan to NATS in the wrong format.
NATS would not comment on whether that was accurate.
Former NATS controller Doug Maclean said he did not know whether the actions of a French carrier were to blame, but believed an “operational glitch” was likely to have happened.
Asked if the problem could reoccur, he replied: “I wouldn’t think that there’s much likelihood of a failure but as long as NATS don’t say anything it’s a perfectly legitimate question.”
He added: “What was the problem? I don’t understand why they’re so closed mouth about it.”
Downing Street did not rule out the possibility that an inputting error by a French airline could have caused the disruption.
The British Prime Minister’s official spokesman said: “There’s going to be, think you’ll know that there’s going to be an investigation by the CAA (Civil Aviation Authority), and a report shared with Government.
“I think (Transport Secretary) Mark Harper confirmed this morning he’ll be getting that in days.
“I’m not going to pre-empt that. I’ve seen, obviously, various bits of speculation, but I’m not going to pre-empt the work that needs to be done.”
But he added that experts had confirmed it was a “technical issue, not a cyber security incident”.
Asked if officials would speak to counterparts across the English Channel, the spokesman said “you would expect them to be speaking regularly” with other countries, “but I’m not aware of any specific conversations with French counterparts”.

People who call their son Jack are also extremely likely to drive a VW Golf and think Mrs Brown’s Boys is the best comedy on TV.
@The Guru: really..I dont have a golf and hate mrs browns boys.
Drive A4 and watch friends ;)
@Mark Murphy: I drive an Audi and hate Mrs brown’s boys with a passion.

@Sequoia: and lots of Mary Lou’s.
@Chin Feeyin: Funny thing when I was a child , my first tea set was a Mary Lou tea set, four cups, saucers ,plates,teapot,sugar and cream jug and four little spoons, they were coloured yellow with red flowers and made in tin by chad valley, they are collectors items now.
I was assured that Mohammed was in the top 5? What’s going on?
@greg merrin: Did Gemma tell you that?
@greg merrin: 78 and creeping up
@Nolan Spare: it’s the most common name in the UK now taking all the different spellings into account.
@greg merrin: Definitely a cover up…can’t see a ‘foreign’ name in the top 20…shows a further cover up of the imminent takeover of Ireland by foreigners with staggering birth rates simultaneously stealing jobs and claiming benefits
@greg merrin: It’s a conspiracy…it’s definitely number 1, as the staggeringly high birth rate of immigrants and them simultaneously taking jobs & benefits is leading to an imminent apocalypse & collapse of Irish society
@Bountyop: Are you a parody account?
@Nolan Spare: You mean it has fallen from 63 last year? That type of creeping up?
I am happy that in each of my 3 kids school years there is not another kid with the same name as them!
@Fergal O’Hagan: can i take a guess. Attracta, Assumpta & Dymphna.
@Fergal O’Hagan: Kim Kardashian can say the same thing how does that make you feel? thats what the world needs more of…pretentious parents with notions
@Keelan O’neill: close, Bingo, Bango and Bongo!!!
@Wheresmyjumper: didn’t go as extreme as her but just gave them regular names that aren’t common. We used our imagination and relatives names!!! Trust me I have no notions!!!
C’mon folks, jack again? Sick of it at this stage. As well as the rest of the downton abbey type names.
@Bart Teeling: Pipe down Bort!
@Bart Teeling: Don’t have a cow man !!
@Chris Linehan: are you talking to me ?
No Keith on the list? Shocked!
Guys, we have enough Jacks now, come on! Show some originality
@Newto2016: the toilet or the names?
Feeling pretty unique
The new boys name which is taken off big time is ‘Theo’,unbelievable numbers calling their child with this name.
Ross is better than Jack
I have a little girl last January and called her Mary-Anne definitely not on the list since 1969
Are you sure that’s not the English list?
3 Rueben’s in my kids class
@Peter Leonard: 4 and you’ll have the makings of a cube.
When I was young I rarely heard of any other boys/girls called Darragh/Daragh. Now we’re everywhere. I turn my head every time I hear someone say the name as I’ve inadvertently been programmed to think I’m the only one and they have be talking to me…
Odhran seems to be the most popular boys name. Makes the list twice. One with a fada and the other without.
@Stevo The Man On A Mission Returns: it appears to have fallen from 63 to 78…
@Bountyop: It increased from 63 to 78.

@Edel Boyle: Repeating yourself isn’t going to move her name up the list, Edel! I’m kidding, congrats and it’s a lovely name!
embed the maps next time lads
I know 6 Noah’s. I have a Jack and dont know another one
@AnnieBelle: all noahs look the same
@AnnieBelle: I heard a fellow in the Rotunda with a really strong Cork accent whose wife just had a boy.
A nurse asked him if they’d come up with a name for their baby boy, “Noah”, he replied. “I’m sure you’ll think of something” the nurse said”… He looked at her like her two heads, “Noah, that’s his name, like”
What is it about giving children shortened names? Charlie instead of Charles, Katie instead of Katherine. I thought only the Americans do that. One day Charlie will be 40 year old, maybe inposition of authority. I mean name them properly and then call them Robie if you want!
I’d a little girl last Jan and named her Mary-Anne definitely not on the list since 1969 lol
Jack was No. 1 and Daniel(s) was No. 5. Did any parents with the surname Burbon name their baby son Jack Daniels?
Obviously made a mistake with my Daughter Emily 2012, but not with Ben 2007
I have a little girl last January and called her Mary-Anne definitely not on the list since 1969
@Edel Boyle: when the Journal says there’s a problem posting you comment they are lying. Does it all the time, just ignore it
