Many airline passengers say the worst a part of any journey is the airport safety test. Worldwide in regular instances, half 1,000,000 individuals go by airport safety each hour. Travellers resent the restrict on LAGs (liquids, aerosols and gels) in cabin baggage, in addition to the duty to extract electronics corresponding to laptops and tablets from hand baggage.

The liquids guidelines have been launched swiftly in 2006 as “a temporary measure” to guard towards explosives. Despite repeated guarantees they continue to be in place.

In 2019 Boris Johnson vowed the principles can be eased at main UK airports by 2022, permitting bigger portions and eliminating the necessity to have liquids individually scanned. Rishi Sunak’s authorities then prolonged that deadline to June 2024.

New scanners are being put in at checkpoints in any respect the UK’s major airports – however not quick sufficient to satisfy the June deadline. The largest UK hubs say they won’t be prepared in time. The transport secretary, Mark Harper, has given airports an extension, however warned that they could possibly be fined in the event that they additional delay the roll-out of smoother safety.

Simon Calder, former safety officer at Gatwick airport and present Independent journey correspondent, explains extra.

Cabin baggage: what are the principles?

The listing of things that can not be taken by an airport safety checkpoints in carry-on luggage has elevated over the a long time, evolving in response to terrorist assaults – profitable and in any other case.

All weapons, whether or not firearms, knives or explosives, are banned from hand baggage. But there are additionally strict guidelines about bigger portions of liquids, aerosols, gels, pastes, lotions and cosmetics, extending even to yoghurt, smooth cheese and Creme Eggs.

No container for any LAG may be above 100ml, and so they have to be carried inside a resealable clear plastic bag with a most quantity of 1 litre.

How did the liquids rule come about?

In August 2006 the aviation business – and baffled passengers – awoke to search out safety guidelines for passengers had tightened in a single day. The authorities introduced that it had uncovered a terror plot to explode transatlantic jets from Heathrow to North America.

The perpetrators aimed to take the components for improvised explosive units on board various plane. The components, derived from hydrogen peroxide, have been supposed to be disguised in smooth drink containers. The plotters aimed to assemble the bombs on board earlier than detonating them and destroying the airplane. They have been later convicted of offences together with conspiracy to homicide and conspiracy to trigger explosions.

The bosses of Britain’s airways have been referred to as within the early hours of 10 August 2006 to be instructed their passengers can be banned from carrying something greater than a handbag or pockets into an plane cabin. Even pens have been banned from transatlantic flights, on the grounds that the ink they contained was a liquid.

One concession was made, for nursing moms: they might take milk for his or her child by the checkpoint, however provided that they tasted it first in entrance of safety employees to show it was the true factor.

Baggage techniques couldn’t address two or 3 times the conventional variety of objects, and Heathrow airport floor nearly to a standstill. Flight networks elsewhere within the UK and Europe have been additionally affected.

Three months later, the principles have been eased – however with strict limits that prevail right this moment at nearly all UK and abroad airports. The limits have been launched as a “temporary measure” whereas airport safety expertise caught up. But progress has been painfully gradual.

Even a really modest rest of the principles – to permit airport purchases of drinks to be taken by checkpoints in a sealed “security tamper-evident bag” (Steb) – took years to be carried out.

Many passengers are nonetheless being caught out, dropping their costly airport purchases, as a result of duty-free drinks are usually not allowed by the airport the place they modify planes.

Is there a technological resolution?

Yes. Modern scanners use computed tomography (CT) – the identical expertise as medical scanners – to analyse the molecular construction of the contents of a passenger’s bag. The nachines can detect any potential menace and current safety officers with a three-dimensional picture of the contents.

They can even analyse whether or not laptops and different digital tools current a hazard.

At airports the place the expertise is used, liquids and laptops not should be eliminated. The package was first utilized in Europe at Shannon within the west of Ireland, the place “liquids, gels, pastes, lotions and cosmetics in containers of any size” have been allowed by safety since March 2022.

Teesside airport and London City airport are additionally now totally up to date.

Travellers have a a lot simpler expertise: they not want deconstruct their cabin luggage, and the entire airport course of feels a lot simpler.

Security is additionally enhanced, with extra refined evaluation of potential threats. The quantity of employees time consumed in “secondary searches” is diminished, permitting officers to spend extra time assessing passenger behaviour.

To scale back stress for passengers and improve safety, in 2019 the federal government instructed all main UK airports to have superior CT scanners at safety checkpoints by 1 December 2022. But the deadline was missed.

During the Covid pandemic, airports confronted catastrophic losses as passenger numbers collapsed. The obligation to make the multi-million pound funding required was lifted.

But smoother journeys are actually again on the desk?

Yes. In 2022, the transport secretary Mark Harper stated the airport expertise would grow to be simpler from June 2024: “The tiny toiletry has become a staple of airport security checkpoints, but that’s all set to change. I’m streamlining cabin bag rules at airports while enhancing security.

“By 2024, major airports across the UK will have the latest security tech installed, reducing queuing times, improving the passenger experience, and most importantly detecting potential threats.”

Some airports, together with Luton and Birmingham, are heading in the right direction to satisfy the June 2024 deadline. But the UK’s 4 largest airports won’t be prepared.

When everybody is prepared, will that be the top of issues?

Not essentially: passenger confusion is a continuing downside for aviation safety. Nothing has modified but, although some travellers might infer that it has.

Worldwide, lack of conformity is a key difficulty for aviation safety professionals – and passengers.

At many airports liquids are restricted however can keep within the traveller’s bag. Laptops and tablets corresponding to iPads have to be eliminated within the UK and plenty of different nations, however in some nations they needn’t be.

In Israel, procedures are completely completely different. The authorities say: “Passengers should arrive three hours prior to departure for the security check procedure.” There is typically intense questioning by officers, and laptops have to be eliminated. But liquids are permitted with out restriction.

The major difficulty: passengers shouldn’t count on aviation safety to be the identical worldwide – and even UK-wide. At some small Scottish airports together with Barra, Campbeltown and Tiree there have been no safety checks since 2017.

Is this going to value me extra?

The airports which can be collectively investing a whole lot of hundreds of thousands of kilos might be searching for a return – and that would embody elevating charges. But the brand new tech ought to reduce employees prices, representing financial savings for airports.

Willie Walsh, director-general of the International Air Transport Association (Iata) – representing airways worldwide – stated: “Implementing this technology should not come with a big bill. In fact, simplified processes should deliver significant efficiencies.”

“Speedy deployment should be possible. The technology has already been used successfully and for a long time at various airports across the world with measurable improvements to the passenger experience.”

Will aviation safety stay a everlasting ache?

No. In 2019 Iata described the prevailing safety state of affairs as “no longer sustainable”. It has been working with airports for over a decade on a undertaking referred to as “Smart Security”.

Ultimately walk-through steel detectors and safety pat-down of many passengers must be eradicated, with expertise assessing potential threats extra successfully than people watching screens.

The passenger ought to be capable to stroll unchallenged alongside a hall flanked by detectors, barely conscious that they’re being checked.

Checkpoints will nonetheless be staffed, however safety personnel might be freed as much as do what individuals do finest, which is to review the behaviour of passengers and determine “persons of interest” for additional investigation.
