A group of European universities, lighting
specialists and aviation companies are
working together to research next-generation
aircraft lighting which delivers the best
environmental conditions for passengers.
Germany's Wuppertal university, the
Fraunhofer Institute for Construction Physics,
Airbus, aircraft interiors and lighting
specialist Diehl Aerospace and German
light manufacturer Osram have joined forces
to determine how aircraft lighting, in terms
of colours and brightness, can be used to
enhance passenger well-being using new,
chronobiologically adapted light.
In a six-day trial using a Diehl model-
aircraft cabin in Nuremberg, the partners
demonstrated that that chronobiologically
adapted lighting based on light-emitting
diodes (LED), particularly on long-haul,
overnight flights, can result in a medically
measurable improvement in sleep, as well
as enhancing well-being and resulting
in greater alertness on arriving at the
Light is the primary stimulus for regulating
the human body clock and can influence
how a passenger rests.
Some 32 participants each experienced
three realistic long-haul, overnight flights
in the simulator. The partners found that
activating LED-based lighting systems
improve rest and comfort for passengers.
During the tests, the lighting was adapted
to the respective phases and times of the
journey using LEDs and intelligent lighting
management systems. The colour spectra
were selected in accordance with the time
of day to support the circadian rhythm (a
person's daily cycle of activity).
During the tests, the participants were
assessed in terms of tiredness, sleep
quality, stress, well-being and alertness
using questionnaires, electrocardiogram
measurements for heart rate, saliva samples
to measure melatonin and stress-hormone
levels, and movement sensors.
The research found that warm, white
light at the beginning of an overnight
Italy's ABC International has launched an in-
flight Trolley Espresso Machine. The machine
can be installed on existing in-flight trolleys,
with ABC providing the modification kit,
espresso machine and batteries.
Alternatively, ABC can provide a trolley
with the machine already installed. The
machine works with coffee capsules supplied
by Italian company Illy Caffe.
ABC is working towards certification
of the unit, which is patented, with first
deliveries scheduled by the end of the
first quarter. The company says it already
has two Italian airline customers and has
embarked on an international marketing
campaign, which will include the machine
being launched at the Aircraft Interiors Show
in Hamburg in April. -- Emma Kelly.

NEWS IN BRIEF
ETIHAD launched its Etihad Wi-Fly in-
flight internet and mobile connectivity
services, delivered via Panasonic's Global
Communications Suite, in December. The
first aircraft equipped is an Airbus A330-
200 flying long-haul routes. The airline will
have ten aircraft equipped by the end of
the first quarter of 2013, with the entire
fleet fitted by the end of 2014. The service
is complimentary to Diamond First Class
passengers, while other passengers are
charged US$24.95 for 24 hours' access.
GERMAN CARRIER Lufthansa has become
the latest airline to test Lufthansa Systems'
BoardConnect in-flight entertainment
system. BoardConnect, which is already
flying with German charter carrier Condor,
has been installed on a Lufthansa Airbus
A320 which operates short-to-medium-
haul routes from Munich. The system
features an onboard infotainment server,
which includes Hollywood movies, digital
newspapers and destination information,
delivered to passengers' laptops, tablet
computers or smartphones.

Stellar Entertainment has completed the
expansion of its production facility in Kuala
Lumpur. The facility, which Stellar says is
Asia's "only truly complete IFE facility",
can now accommodate 20 more personnel
and offers expanded dubbing facilities
and digital capturing, archiving and
transcoding. The Australian company first
opened a facility in Kuala Lumpur in 2005
and has expanded it three times since then.

flight contributes to relaxation, promoting
melatonin production and a slower heart
rate, resulting in better sleep.
Meanwhile, cold, white light, with a high
blue content, on the morning after a restful
sleep can help passengers be more alert on
reaching their destination by suppressing
the excretion of sleep hormone melatonin. --
