Qantas working with Airbus, Sydney’s Charles Perkins Centre and Caon Design Office has created lightning to reduce Jetlag for its A350s for ultra-long-haul flights.

The design is a result of more than 150 hours of testing in the Airbus Customer Definition Centre in Hamburg where representatives from Qantas, Airbus, the University of Sydney’s Charles Perkins Centre and Caon Design Office created and tested hundreds of lighting patterns and sequences in an Airbus A350 cabin mockup.

Qantas and the Charles Perkins Centre last year released preliminary findings on how to potentially reduce the impacts of jetlag by reshaping the inflight travel experience, based on world-first research conducted during test flights for Qantas’ Project Sunrise program.

Based on state-of-the-art modelling of circadian rhythms, the Charles Perkins Centre advised the optimal spectral irradiances for light to promote circadian adaption, sleep, and wake. These were implemented and tested throughout the lighting workshops in Hamburg and adjusted for eye comfort and appearance.

The lighting sequence will be tailored to help passengers adjust to their destination time zone before they set foot on the ground.

Qantas said that the trial has produced a series of 12 unique lighting scenes specifically for the Project Sunrise flights, including:

• “Awake”: Broad-spectrum, blue-enriched lighting to help customers adjust to the destination time zone and help them stay awake; a softer version is available for crew to choose based on cabin mood and ambience.
• “Sunset”: An immersive transition from a daytime mode into dark that moves through the colours of a sunset into a night sky with moonlight and slow cloud effect to relax customers and prepare them for sleep.
• “Sunrise”: Dynamic lighting effective for a transition from night to day that replicates an Australian sunrise rolling from the front of the cabin to the rear.

The main cabin will also have Welcome and Farewell lighting scenes for boarding and disembarking, as well as tailored scenes for taxi, take-off and landing, and sleep.

The Wellbeing Zone will feature soft blue-enriched light creating a daytime sky effect with slow-moving clouds during ‘the day’ to keep customers awake, and a moonlight-inspired scene with reflections of water rippling to relax customers who spend time in the Wellbeing Zone while the rest of the cabin is in a dark period.

In a first for the airline, the six enclosed First Suites will offer a fully customisable lighting sequence for their environment which means customers can choose the time zone they want to be on for the duration of the flight.

Qantas International CEO Cam Wallace said that the scientifically informed lighting design was another
critical component of the preparation for Project Sunrise flights, which will connect Australia’s east coast
non-stop with London and New York.

“These world-first flights have been an opportunity for us to work with experts and build on our experience of long-haul flying to rethink the inflight experience with a focus on customer wellbeing and combating the effects of jetlag,” said Mr Wallace.

Australian Industrial Designer David Caon said the lighting workshops followed more than five years of cabin design with Qantas to maximise customer well-being inflight.

“Aircraft lighting doesn’t cross the mind of most travellers but the external light cycle of night and day has more impact on our circadian rhythm and the impact of jetlag than any other factor,” said Mr Caon.

“The Charles Perkins Centre provided us with the ideal spectral irradiance for wake and sleep and these workshops were about crafting a beautiful ambience which was guided by that science and exceptional design principles.

“Every part of the Project Sunrise A350 cabins was specially designed for Qantas and creating this tailored lighting sequence is one of the final pieces of the puzzle.”

Joost van der Heijden, SVP & Global Head Of Marketing, Airbus Commercial Aircraft said “The A350 Airspace cabin has been designed to provide passengers with the best possible flight experience. This includes more personal space, the quietest cabin in the sky, the highest air quality and full connectivity throughout. And the unique and innovative state-of-the-art LED lighting system offers over 16 million colour combinations, enabling airlines to fully customise their offerings.”

The Wellbeing Zone was recently recognised at the Crystal Cabin Awards, taking out the category of ‘Passenger Comfort’ on the specially designed A350.
