UK air traffic control meltdown caused by error with a ‘1 in 15 million’ chance

Published

on

Systems crashed causing 1,500 flights to be cancelled, leaving thousands of passengers stranded abroad.

The technical glitch which caused last week’s flight chaos in the UK was a “one in 15 million” event, according to air traffic service NATS.

On 28 August, thousands of passengers were left stranded after 1,500 flights were cancelled during one the busiest parts of the summer season.

The service says the chaos was caused by a single flight plan that wasn’t properly processed by part of its system, causing it to shut down automatically within a matter of seconds.

A new report released on Wednesday (6 September) by NATs outlines how this extremely rare error occurred.

The UK’s National Air Traffic Services (NATS) has confirmed the root cause of the meltdown in the preliminary report released today.

Airlines are required to submit the path of every flight that passes through a country’s airspace to its national control centre. In the UK, these should automatically be shared with NATS controllers who oversee the country’s skies.

The report from NATS found that one flight plan with two identically named but separate waypoint markers outside of UK airspace was behind the technical glitch.

These waypoints, which represent locations along an aircraft’s route, are identified by a series of letters and numbers. The two identical points in the problem flight plan were 4,000 nautical miles (7,408 km) apart but shared exactly the same name, forcing the system to stop working for safety reasons.

“In these circumstances, the system could not reject the flight plan without a clear understanding of what possible impact it may have had. Nor could it be allowed through and risk presenting air traffic controllers with incorrect safety-critical information,” NATS said.

A backup system also failed and no correct information was sent to air traffic controllers. This series of events unfolded in just 20 seconds.

It meant that the service couldn’t process flight plans automatically for several hours and instead had to switch to a slower, manual process. The number of plans NATS could handle dropped from 400 per hour to as low as just 60, causing more than a quarter of flights to be cancelled.

An extremely rare error

Around 250,000 people were affected by the disruption while delays and cancellations continued for two more days as planes and crews were left out of position.

When asked the odds of an incident like this occurring, NATS chief executive Martin Rolfe told the BBC it was around “one in 15 million”. The system that failed has processed 15 million flight plans in the five years it has been operating and this was the first time this set of circumstances has been seen.

This is also why it took engineers a number of hours to figure out how to fix the problem.

Rolfe added that the system did “what it was designed to do” – fail safely when it receives data it is unable to process.

NATS says it has taken measures to ensure that the same glitch doesn’t happen again and emphasised that safety was never compromised during the event.

Spain orders removal of more than 65,000 Airbnb tourist rentals it says violate regulations

Spain has launched a major clampdown on Airbnb properties, ordering the removal of over 65,000 holiday rental listings across the country that fail to comply with regulations.

The Spanish Consumer Rights Ministry cited several violations, including missing licence numbers, not specifying whether the owner was an individual or a corporation, and discrepancies between listed information and official records.

The crackdown comes against the backdrop of Spain’s growing housing affordability crisis, which has sparked widespread protests over rising rents and home prices.

Many Spaniards blame short-term rentals on platforms like Airbnb for worsening housing shortages, particularly in popular tourist destinations like Madrid and Barcelona.

‘No more excuses’

On Monday, Spain’s Consumer Rights Minister Pablo Bustinduy said the move aimed to address the general “lack of control” and “illegality” in the holiday rental business.

“No more excuses. Enough with protecting those who make a business out of the right to housing in our country,” he told reporters.

The nationwide enforcement primarily targets listings in Madrid, Andalusia, and Catalonia, where tourism is most heavily concentrated.

The ministry said it had notified Airbnb about the noncompliant listings months ago, but that the company had appealed the move in court.

Spain’s government said Madrid’s high court had backed the order sent to Airbnb.

Bustinduy said it involved the immediate removal of 5,800 rental listings from the site. Two subsequent orders would be issued until the total of 65,935 removals is reached, he said.

Airbnb intends to appeal new ruling

Official data shows Spain had approximately 321,000 licensed holiday rentals as of November last year- a 15 per cent increase since 2020 – with many more operating without proper licenses.

The Consumer Rights Ministry opened an investigation into Airbnb in December last year.

Airbnb told Euronews Travel it will continue to appeal against all decisions linked to this case.

“No evidence of rule-breaking by hosts has been put forward, and the decision goes against EU and Spanish law, and a previous ruling by the Spanish Supreme Court,” a spokesperson said.

“The root cause of the affordable housing crisis in Spain is a lack of supply to meet demand. The solution is to build more homes – anything else is a distraction.”

The spokesperson added that governments across the world are seeing that regulating Airbnb does not alleviate housing concerns or return homes to the market: “It only hurts local families who rely on hosting to afford their homes and rising costs.”

Barcelona bans short-term rentals

Last year, the Spanish government launched a general crackdown on holiday rentals amid growing frustration among residents who say mass tourism is aggravating a housing crisis.

Locals say they are being priced out of their cities due to gentrification and landlords favouring more lucrative short-term tourist lets.

Barcelona has already taken aggressive measures to address the problem, announcing plans to eliminate all 10,000 licensed short-term rental apartments by 2028 to prioritise housing for permanent residents.

Brits could soon enjoy shorter passport control queues at EU airports. Here’s why

Published

on

British holidaymakers will soon be able to use e-gates at more EU airports, the UK government has announced.

It comes as part of negotiations between the UK government and the European Union to finalise a ‘post-Brexit reset deal’.

It means British passport holders will no longer have to wait at manned desks and will instead be allowed to use fast-track e-gates usually reserved for EU or European Economic Area citizens.

EU Relations Minister Nick Thomas-Symonds said this would give British travellers “more time to spend on holiday or work trips […] doing what you want, not being stuck in queues.”

The UK government said the move would end “the dreaded queues at border control.”

UK travellers have to join ‘other nations’ queue at EU airports

Following Brexit, UK citizens forfeited their privileged status when travelling to EU countries.

They now fall into the ‘visa-exempt third-country nationals’ category – the same classification as travellers from dozens of countries, including Australia, Canada, New Zealand and Singapore.

This has meant British travellers must join the ‘other nations’ queue at border control rather than using the expedited EU lanes.

The requirement to check that British travellers meet entry conditions is a significant obstacle to allowing them to use the fast-track lanes.

EU border control has to verify that UK travellers are not in breach of the 90-day stay limit in 180 days and that they have the means to return to their country of origin, i.e. a flight ticket out of the EU.

Frontier officials must also stamp the passenger’s passport.

This change often translates to extended waiting times, especially at busy European airports like Amsterdam Schiphol, Milan Malpensa, and Paris Charles de Gaulle.

Waits exceeding an hour have become commonplace, especially when arriving shortly after large international flights.

These delays affect not only entry into EU countries but also departure, as British travellers must undergo exit checks that sometimes result in missed flights due to lengthy queues.

UK travellers will be able to use e-gates at many European airports

Under the new deal, British travellers will be able to take advantage of the faster e-gate passport checks at many EU airports.

No details have yet been released on when this will be introduced and where, although the BBC reported that British Prime Minister Keir Starmer “has called on all EU members to co-operate without delay.”

Some EU airports will likely allow UK travellers to use existing e-gates reserved for EU citizens, while others may install dedicated ‘third-country national’ e-gates.

The latter are already in place across Italy, including Venice Marco Polo and Rome Fiumicino, as well as at Amsterdam Schiphol and Lisbon.

With this system, once the traveller passes through the gate, there is a brief check by border officials who will also stamp passports.

Brits will use e-gates in all airports after introduction of EES

In addition, the UK government underlined that there will be “no legal barriers to e-gate use for British Nationals travelling to and from European Union Member States after the introduction of the European Union Entry/Exit System [EES].”

The EES is scheduled to come into force in October this year. The system will register non-EU visitors who don’t need a visa digitally, removing the need for physical stamps.

New pet passports will make it easier for Brits to bring pets into EU

The UK government also announced that new pet passports will be introduced as part of the deal.

This means UK cats and dogs will be able to travel “more easily” from the UK into the EU by “eliminating the need for animal health certificates for every trip.”
