Unique and customisable cabin lighting inspired by the colours of the Australian landscape and grounded in science will feature on Qantas’ upcoming Project Sunrise ultra-long-haul flights to help minimise jetlag and improve customer wellbeing.

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 mock-up.

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.

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.

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

Qantas will be the first airline in the world to offer a purpose-built Wellbeing Zone located between the Premium Economy and Economy cabins featuring sculpted wall panels and integrated stretch handles, guided on-screen exercise program, a hydration station and a range of refreshments.
