Airports Council International (ACI) World has released a new guide on computed tomography (CT) screening technology to increase efficiency and improve passenger experiences.

The Advanced Cabin Baggage Screening / Computed Tomography (CT) Implementation Guide emphasises the advantages of using CT technology for the cabin baggage screening process.

The guide was developed by ACI’s Smart Security Management Group, which includes airports, regulators and airlines.

It highlights the different measures and suggested actions that need to be adopted before and during the installation of the technology.

ACI World’s Smart Security programme lists improvements that can be made to the screening process by the deployment of current and emerging technologies.

ACI World director general Angela Gittens said: “ACI’s Smart Security programme explores how security checkpoints could be designed by providing airports with operationally viable solutions, which help maintain security while increasing operational efficiency and passenger satisfaction.

“Smart Security also looks beyond mid-term solutions and focuses on risk-based security concepts, innovative processes and advanced screening technologies that will help achieve a truly seamless passenger journey through airports.”

Australia, the Netherlands, Singapore, the UK and the US are some of the countries that are currently taking the lead in deploying CT equipment for airport passenger screening.

Other countries and airports have initiated CT technology trials.

According to Smiths Group’s annual results ending 31 July, the US Transportation Security Administration has placed a $96.8m order for CT cabin baggage scanners.

This June, London Heathrow Airport announced a £50m investment for CT technology, with plans to deploy scanners by 2022.

Passengers will benefit from the use of CT technology, which allows them to keep their liquids and electronics inside their cabin baggage.

In October, ACI World published its Annual World Airport Traffic Forecasts (WATF) report, which forecasted global air traffic to grow at a rate of 3.7% per annum, reaching 19.7 billion by 2040.
