An in-line baggage screening system is scheduled to start functioning in both international and domestic terminals at the Netaji Subhas Chandra Bose International (NSCBI) Airport in Kolkata, India.

The installation of the system is expected to be completed by the end of June this year, when various security agencies will test the system.

Netaji Subhas Chandra Bose International Airport director Kaushik Bhattacharya told The Telegraph: “Today we decided that the installation of the system in the international and domestic sections should be completed by June-end and the system will be ready for tests. The system will be functional by the end of August.”

Once the system becomes functional, passengers will deposit their registered luggage at the check-in portals of the respective airlines without getting it scanned by stand-alone X-ray machines.

Passengers currently have to stand in a queue to get their luggage scanned by the stand-alone machines.

“Portal A in the domestic wing cannot be linked to the in-line system by August because of logistical issues.”

In 2016, an in-line baggage screening system was launched in the international terminal but was withdrawn temporarily to upgrade the system.

Airport authorities told the publication that the modernised system is being deployed at the three check-in portals in the international section.

The system has already been installed in four of the five check-in portals in the domestic section.

“Portal A in the domestic wing cannot be linked to the in-line system by August because of logistical issues,” an official told the news agency.

Once the deployment is completed, the securities agencies will carry out two sets of examinations.

As part of the project, X-ray (CTX) machines that capture three-dimensional (3D) images of baggage are being installed.

“Conventional X-ray machines provide two-dimensional images. Screeners sit beside the machines and examine the images. After the CTX in-line X-ray machines become operational, the screeners will sit at a remote location, to be called Level 2 room,” Bhattacharya added.

The US Transportation Security Administration (TSA), which operates under the Department of Homeland Security of the US, will carry out the first test.

The second and final round of tests will be conducted by the Indian agency, Bureau of Civil Aviation Security (BCAS), allowing it to be commissioned.

“The system cannot be made functional without the bureau’s clearance,” an official added.
