The new standard means passengers can leave electronics – laptops, tablets, mobile phones, cameras – in their hand luggage for scanning. This reduces passenger preparation time and the number of trays which, in turn, creates a faster, simpler and more efficient screening process. “We no longer need random trace detector searches, which is a major improvement for both passengers and operators,” added Søren Bjerg. “And we have achieved the ultimate aim of significantly increasing throughput.”
Previously, operators had to stop screening, ask people to remove large electronic devices from their bags, then rescreen the bag itself and also the device. This time consuming process has now been eliminated and tray usage has been reduced by at least 30%. Initially, throughput slowed slightly as operators became accustomed to looking at the more complex images, but they adapted very quickly and returned to previous evaluation levels. Very little additional training was required.
The C2 upgrade did bring an increase in the alarm rate but this was more than compensated for by faster passenger divestment and a more streamlined overall process. Alarms are easily dealt with using on-screen evaluation, followed by a manual, secondary check if the operator is still concerned. Otherwise, the bag is simply accepted – a manual check is not required for every alarm.
