How does the new CTX machine at Bengaluru airport ensure reduced waiting time during security checks?

Installation of this technology comes in view of a Bureau of Civil Aviation Security (BCAS) report that has directed big airports to install full-body scanners and CTX machines by December 31, 2023. Airports that handle over 50 lakh passengers annually have been asked to install these machines. Here’s a low down on how CTX aims to reduce time during security checks and ensure a seamless experience for passengers.

What is the CTX machine and how does it work?

The machine is an advanced cabin baggage screening system based on Computed Tomography (CT) technology. It uses advanced CT X-ray technology to create 3D volumetric images of a bag’s inside that reveal its contents. It also allows for automatic detection of explosives with low false alarm rates.

The CTX machine is also integrated with the Automatic Tray Return System and the full body scanner system, thus ensuring a seamless and hassle-free security scanning process. Currently, there are three full body scanners installed at Terminal 2 of Bengaluru airport.

How will this improve passenger experience?

Unlike the current system in which passengers have to take out their electronic items like laptops, mobile phones, besides LAGS (liquids, aerosols, and gels) and place it in trays, the new technology allows passengers to leave such items in their bags for a quicker screening process. With this, the authorities aim to reduce processing time at security checkpoints. Eliminating the need to remove many items from the luggage, also reduces the contact points (frisking) as well as the demand for trays, which speeds up the process.

How do CTX machines maintain safety and security standards?

The advanced screening of carry-on baggage using CT and automatic explosives detection algorithms ensure an improved security outcome with superior 3D image quality. CT can also better identify the density of liquids. The CTX machine is also designed to identify potential threats and help combat the movement of unsafe, undeclared or illegal items.

What is the operational efficiency of this technology?

Operators can rotate the view to look at the contents of bags, cutting down on re-checks and physical inspection. The technology is also designed for automated detection of prohibited dangerous items and currency. The EDS CB C3-approved system eliminates the need to remove large electronics and liquids from cabin baggage.

CTX can automatically detect a variety of threats, controlled and prohibited items without impacting the speed of the overall image evaluation. The additional detection capabilities provide invaluable support to all image analysts, reducing the burden in decision-making, and are particularly helpful for less-experienced operators. It is intuitive, easy to use and requires little or no training. The increase in operational efficiency also leads to a faster, more streamlined experience for passengers and visitors who have to pass the checkpoint.

Will this initiative be implemented only at T2?

The CTX Proof of Concept (POC) is initially to be used on a trial basis at Terminal 2 of Bengaluru airport only for domestic passengers. The installation and integration with ATRS lanes are currently underway and the trial is expected to begin by the first week of December.
