Singapore Changi trialling new computed tomography (CT) security screening technology

Singapore Changi is conducting trials of new 3D screening technologies that if successful could mean that passengers no longer have to remove laptops and other electronic devices from baggage at security checkpoints. 

The trials, which are being conducted at two boarding gates at Changi Airport Terminal 3 until June 2016, involve the use of computed tomography (CT) security screening for hand luggage.

Passengers currenty have to take electronic devices such as laptops and tablets out from their hand-carry luggage and place them on a separate tray for screening.

However, using advanced 3D screening technology, the new CT screening equipment allows them to keep such electronic devices in their hand-carry luggage, ultimately saving them time and delivering what it hopes is a "better airport experience for passengers".

Airport operator, Changi Airport Group (CAG), is also trialling a new automated tray return system useable by two passengers simultaneously and new enhanced body scanning equipment that uses millimetre wave technology to detect both metallic and non-metallic items.

Passengers, after removing items in their pockets or on their body, simply need to walk into the body scanner and be scanned, a process that takes a few seconds.

CAG is quick to point out that the millimetre wave technology has been certified to be safe and poses no known health and safety risks as it utilises a very low-power non-ionising form of electromagnetic technology. 

It states: "The amount of electromagnetic radiation emitted by millimetre wave security scanners is many times smaller than that emitted by a mobile phone. The scanner complies with the standards set by the US Food & Drug Administration, American National Standards Institute and United Kingdom Health Protection Agency".

Alan Tan, CAG’s vice president of aviation security, says: “At Changi Airport, we take safety and security seriously and are committed to maintaining the highest

standards. We work very closely with the authorities to review and adopt new advanced technologies and process innovation to improve security screening and
enhance the passenger experience at Changi.

“The data and passenger feedback we collect from the trials will help us assess the effectiveness and operational efficiencies of these new systems, before we ascertain their suitability for implementation at the airport.”
