CT Technology: Principles and Advantages
The newly installed scanners use Computed Tomography (CT) technology, primarily known from the medical field. Unlike conventional X-ray machines, they generate a 3D image of the baggage, enabling detailed cross-sectional views. This provides security operators with a more sophisticated view of the contents, allowing for more precise identification of potentially hazardous items.
The main advantages of this technology include:
-
Significantly higher detection accuracy for dangerous substances,
-
The ability to leave liquids and electronics inside baggage,
-
Faster passenger processing at security checkpoints,
-
An enhanced passenger experience while maintaining high security standards.
Current Restrictions Remain in Place
Despite this technological readiness, the restriction on carrying liquids in cabin baggage—limited to containers of 100 ml—remains in effect across the European Union. This measure was introduced in 2006 following the discovery of a terrorist plot involving liquid explosives. Any revision of this rule depends not only on technological advancements but, crucially, on a regulatory change at the European level.
The European Commission has previously tested easing these rules, including a trial that raised the limit to 330 ml at some airports, but these measures were ultimately withdrawn. The primary reason was the lack of uniform certification standards for different types of CT equipment, which created an inconsistent security environment across member states.
Potential Changes in 2025
According to Prague Airport, the European Commission could issue a new regulation allowing larger quantities of liquids as early as autumn 2025. In practice, this would mean the end of the 100 ml limit, with passengers permitted to carry liquids in containers of 300–500 ml, or potentially up to 2 litres per person, as has been considered by the industry body ACI Europe.
In the initial phase, the change would apply only to Terminal 2 (flights within the Schengen Area), where the new technology is already installed. Terminal 1 is scheduled for modernization in the coming years.
In Summary
With the installation of CT technology, Václav Havel Airport Prague is prepared for a fundamental change in cabin baggage regulations. However, the decision to lift or raise the liquid limit rests solely with the European Commission. If the change is approved, passengers could be enjoying the benefits of modern screening without the familiar restrictions by the end of 2025.
Until then, the current rules remain in full effect, and passengers must continue to carry liquids in containers no larger than 100 ml, all placed within a single, transparent, resealable 1-litre plastic bag.
