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.

Flying on a plane is safer now than ever before, study finds

Published

on

A recent study has found that flights are safer than they’ve ever been.

There’s a one in 13.7 million chance that a passenger anywhere in the world will die onboard an aircraft, according to a new study.

Researchers from the Massachusetts Institute of Technology (MIT) in the US analysed global passenger and fatality data between 2018 and 2022 and found deaths on planes dropped by an average of 7 per cent year over year.

Those results follow a pattern of “continuous improvement” that started in 1968 when the death rate fell an average of 7.5 per cent per year even as more flights took off and landed.

It comes as US aircraft manufacturer Boeing faces a series of technical issues that forced the company to ground the test flights of their 777-9 model. The Federal Aviation Authority (FAA) also reportedly has launched inspections into the 787 Dreamliner due to faulty pilot seat movements.

Death rate 36 per cent higher in some countries

The incident rate depends on what countries people are flying to and from, with researchers dividing countries into three tiers for low, medium and high risk based on air safety record.

The lowest risk is the Tier 1 group which includes the European Union, Australia, Canada, China, Israel, Japan, Montenegro, New Zealand, Norway, Switzerland, the United Kingdom, and the United States.

Some examples of countries in the Tier 2 group include Bahrain, Bosnia, Brazil, Brunei, Chile, Hong Kong, India, Jordan, Kuwait, Malaysia, Mexico, Philippines, Qatar, Singapore, South Africa, South Korea, Taiwan, Thailand, Turkey, and the United Arab Emirates.

The rest of the world’s countries are in Tier 3 or the high-risk group.

For the first two tiers, the death risk falls to one per 80 million passenger boardings, the study found. These countries account for more than half of the world’s 8 billion people.

“At that rate, a passenger could on average choose one flight at random every day for 220,000 years before succumbing to a fatal accident,” the report continued.

The fatality risk is around 36 per cent higher for tier 3 countries, the study found, but fatalities are still falling.

“While [these nations] continue to get better over time, their passenger death risk remains many times as high as the risk elsewhere,” the study says.

The study also didn’t include any accidents that were direct attacks on passengers, like a suicide bombing at Kabul airport in 2021 that killed 170 Afghans and 13 US military troops.

Over 4,000 deaths from catching COVID on a plane

The study accounts for the COVID-19 pandemic which they defined as the period from March 2020 to December 2022. While there were fewer airline passengers during the pandemic, those who travelled faced a “new source of danger” if exposed to the virus on a flight.

Airlines at the time told passengers that COVID-19 transmission was “all but impossible,” the researchers say in their study, even though the US surgeon general estimated that 96 per cent of flights during that time had at least one positive passenger.

Despite that new risk, researchers say that there “is no evidence that those who did fly suffered a greater risk of death from plane crashes or attacks than would have been expected had the pandemic never occurred”.

“Outside of on-board transmission of COVID-19, passenger safety did improve sharply,” the study said.

In total, the paper estimates that roughly 4,760 people died from contracting a COVID-19 infection on a flight from March 2020 to December 2022.

The MIT researchers do admit that it’s hard to know the exact number of deaths since passengers who got an infection after a flight could’ve passed it on to others who might have passed away.

“These estimates about COVID-19 deaths are necessarily imprecise,” the study says. “And while they use lower-end parameter estimates, they could well be too high”.

Their data also doesn’t count any passengers under 18 and doesn’t differentiate the age of any passengers over 65, which the researchers say is important because mortality goes sharply up for the elderly.

‘Paradise ruined’: Why Spanish locals fed up with overtourism are blocking zebra crossings 

Published

on

In northwestern Spain, villagers blocked zebra crossings to protest too many tourists – but ended up causing a huge traffic jam.

Spain has seen many overtourism protests this year, but one small village has been making its grievances known in a very unusual way.

In the Galician village of O Hío in northwest Spain, locals took it upon themselves to protest against the volume of tourists by blocking zebra crossings.

Walking up and down them for a total of 37 minutes, they caused total traffic gridlock – worsening the exact problem they hoped to highlight.

Nevertheless, residents stand by their decision.

Why are Spanish locals blocking zebra crossings?

“Traffic problems are already common, but this year they have tripled at least,” resident Mercedes Villar told local newspaper La Voz de Galicia. “It’s an avalanche of cars that not only pollutes but also affects everyone’s lives because they park wherever they want. We have the right to live too.”

Locals from the small coastal village say, while they’re not against tourism per se, they want authorities to find a mutually beneficial solution so that residents and visitors can co-exist happily.

They say their driveways are being blocked, traffic accidents are increasingly common and that parking-controlling yellow lines are being ignored.

“The protest was meant to raise awareness and sound the alarm,” another villager told La Voz. “We want people to be civil and understanding and, if they see that there is no parking space, to leave, as we all have to do in any city.”

Rogue parking by tourists creates ‘danger’ for locals

Villar, who is the spokesperson for the residents’ association, added that while locals tend to park their cars properly, visitors who don’t are creating “a situation of insecurity and danger”.

Villagers raised concerns that the situation causes access problems for emergency vehicles, citing residents who needed to be collected by ambulance, but found the exits from their houses blocked or their transport delayed due to the sheer number of vehicles on the streets.

Speaking to La Voz, Villar added that the significant amount of traffic had led to “uncivil” behaviour, including visitors littering the roads and parking areas.

She also says that too much traffic has led to the deterioration of some roads. “We want orderly and polite tourism that respects the environment. This is a paradise, but paradises also get ruined,” she said.

Locals have been invited to discuss their complaints

Like many Spanish people protesting against overtourism, Villar believes that the growing popularity of her local area has a lot to do with social media’s impact.

“This is sold as a beautiful place with no people, but now that is not true,” she explained, adding that residents tend to avoid beaches during tourist season as they are simply too busy.

She hopes that the zebra crossing protests will have laid bare how “annoyed” locals are with the situation.

It seems to have worked – in response, the local council has invited disgruntled locals to a meeting to discuss their complaints later in September.

From Cantabria in the north to Málaga in the south, growing numbers of Spanish people are calling for the government to change the face of mass tourism, which they believe is getting out of hand.

They say its impact is having a negative effect on property prices and rents as well as standard of living for residents.
