Further security enhancements were on display at
the departure gate. A cargo zone also showcased the
innovative cargo-scanning systems.
The technolog y on display included camera
tracking , infra-red facial recognition, intelligent
security queue management using a barcode reading
solution, handheld body scanners to detect explosives,
rapid footwear screening which doesn't require the
removal of shoes, electromagnetic liquid scanners and
multi-spectral x-ray detectors.
e project "is now completed," ales said, with
the company in late January having submitted a nal
report to the government, including detailed analysis
of the trial results.
Meanwhile, on the other side of the world, the
Australian Government late last year tested new
technolog y to detect explosives in liquids, aerosols
and gels at Sydney and Melbourne airports. e
Liquids, Aerosols and Gels Advanced Technology
Trial was conducted in conjunction with the United
States and UK as part of an international approach
to enhancing aviation security, the Australian
Department of Infrastructure and Transport said.
e results of the trial are designed to contribute to
e orts to remove liquid restrictions on international
ights in the future, the department said.
On trial were two types of equipment capable of
detecting liquid-based explosives, advanced x-ray for
carry-on baggage and bottled liquid scanners.
e tests were conducted between 24 November
and 4 December at Melbourne Airport's Terminal
4, and between 29 November and 10 December at
Sydney Airport's Terminal 2.
e equipment on trial at Melbourne Airport
was the Rapiscan Advanced Technolog y 620DV
x-ray inspection system, the CEIA EMA-3 liquid
scanner and the ermo Fisher Scienti c Truscreen.
The Rapiscan system uses a second x-ray scan
perpendicular to the rst, allowing screening o cers
to view baggage from multiple angles.
e additional data allows the system to use an
automated algorithm to indicate the location of
potential threats, including solid and liquid explosives
in carry-on baggage by analysing material density
using the independent views. Bags and trays are put
on the conveyor belt, which feeds them through the
system in the same way as baggage screeners do today.
The CEIA system uses electromagnetic fields
to determine whether a liquid is innocuous or a
potential threat. Bottles and other containers are
placed in the bottle scanner. e electromagnetic
elds generated by the device are weak in intensity
and non-ionising so they are safe for liquids, according
to the department. e TruScreen bottle scanner uses
Raman spectroscopy to detect threat substances in
liquids carried in containers.
The Sydney Airport trial involved the CEIA
EMA-3 and two systems from Smiths Detection
-- the Hi-Scan 6040aTiX and the Responder BLS.
e Hi-Scan x-ray inspection system uses automated
explosive detection systems to detect explosives in
carry-on baggage by analysis of the atomic weight
and material density using four independent views.
Bags and trays are put on the conveyor belt which
feeds them through the system in the same way as
existing baggage x-ray screeners. e Responder BLS
is a desktop system that uses Raman spectroscopy
technolog y to distinguish threat liquids from benign
"Over 7,000 people took part in the trial and
overall passengers responded well to the trial," the
Department said. e data collected during the trial
is being analysed to inform policy and screening
process options and no further trials are planned at
the moment. e government said a report on the
trials will be released in the coming months, a er
which the decisions will be made on the use of such
Under the Australian Government's A$200 million
(US$214 million) Strengthening Aviation Security
initiative, A$28.5 million will be provided to assist
the industry in introducing a range of new screening
technologies, including next-generation multi-
view x-ray machines and bottled-liquid scanners
at passenger screening points at Australia's eight
international gateway airports. Assistance will
initially be provided for equipment installation at
international transit and transfer screening lanes, the
Many in the industry look forward to the li ing
of restrictions on the carriage of liquids and gels, but
believe that the technology is not currently mature
enough to allow this.
" e threat from liquid explosives and suicide
terrorists is still very real and so any change needs
to be considered in the context of a risk assessment,"
says Craig Bradbrook, ACI's director security and
facilitation. "Liquid explosive detection [LED]
systems should in due course allow for the routine
screening of all LAGs and so the restrictions should
be li ed. However, we do not yet consider the LEDs
technolog y to be mature enough or sufficiently
proven in an airport operational environment. False
alarm rates of some equipment are too high." n
IATA wants to shift security emphasis from dangerous objects to dangerous people.
