Many elements contribute towards providing passengers
with a positive in- ight experience -- from friendly
cabin sta and a good meal to comfortable seats and
enjoyable in- ight entertainment. Even cabin lighting
and a well-designed lavatory play a role. Airlines and
their suppliers consider all these aspects as they work
towards improving the passenger experience, distinguishing their product from
their competitors and delivering cost, maintenance and weight bene ts.
Cabin lighting, for example, is now a major consideration in any new aircra
programme. A ra of lighting options are available to operators, including
mood lighting, wash lighting and coloured lighting, much of which is delivered
through light-emitting diodes (LEDs), which have a longer life than alternative
light sources -- lasting ten to 20 times longer than incandescent lights -- and
generate less heat.
e Boeing 787, the rst aircra to be exclusively equipped with LED
lighting , has set a new benchmark. Diehl Aerospace of Germany was responsible
for the cabin lighting on the new twin-aisle twinjet, and has also secured the
contract for the Airbus A350 XWB.
On the 787, the cabin lighting can be dimmed smoothly down almost
to complete darkness and can change from white to a wide range of other
colours. As a result, operators can simulate full daylight, then gradually
change to night lighting.
"Lighting scenarios like sunrise, candlelight, work light, among others, are
possible and a matter of so ware parameters only," says Diehl. Full brightness
can be delivered without white uorescent tubes in any colour tone.
All of this means a better experience for passengers. With some humans
receiving about 80 percent of their environmental information optically, cabin
lighting can have a huge e ect on how passengers feel. Illumination can be
matched to each phase of ight, contributing to passengers sense of well-being
and a ecting biorhythms to help alleviate the symptoms of jet lag.
Today s modern, LED-based lighting systems are also good for airlines.
Diehl says its LED lighting o ers bene ts in terms of life, maintenance, weight
and power consumption. e lights also feature technology that maintains
brightness and colour-consistency over the life of the product, rather than
fading and changing with age.
Improvements in lighting, seating and even lavatories are aimed at making the in-flight experience more comfortable
and efficient than ever before, writes Emma Kelly.
"Overall, modern and optimally integrated LED
illumination leads to double-digit percentages
of savings in terms of power, maintenance and
weight." -- Diehl
EMTEQ's Daylight is a white lighting
system that replicates natural lighting
inside the cabin.
