As one of the first airlines to roll-out high-speed Wi-Fi connectivity across its entire fleet of aircraft, Icelandair turned to STG Aerospace to effectively communicate this major enhancement in the passenger experience on its fleet of Boeing 757 aircraft.
 
Through a powerful combination of photoluminescent and LED technology, the new PSU lens removes the need to backlight the No Smoking icon by moving it to a central position and illuminating the command with blue glowing photoluminescence, ensuring the sign is always visible even in low light and dark conditions. 

 
Creating a switchable display on the left, now converted to LED, the No Smoking icon has been changed to a Wi-Fi icon, allowing airlines to manage the availability of the service and advertising to passengers that Wi-Fi is available on-board.
 
Dr Sean O’Kell, Director of Innovation at STG Aerospace, commented: “When Icelandair approached us, we were only too pleased to respond. By applying our commitment to innovation and our expertise in both photoluminescent and LED technologies, we were able to rapidly develop an elegant solution and, using our in-house facilities, bring a new product to market in a remarkably short space of time.”
 
Sigurður Ingi Ljótsson, Industrial Designer at Icelandair, said: “Our long-standing relationship with STG Aerospace made them a first choice for this PSU upgrade project. By changing the switched no-smoking symbol for a Wi-Fi available one, we can let passengers know in the day or night that Wi-Fi connectivity is available on our planes.”
 
In addition to the practical and aesthetic benefits, the new patented PSU lens is a lighter, simpler, retrofit solution that can be customised to provide effective on-brand messaging to all passengers on-board. To complete the modernisation process, STG Aerospace offers direct, filtered white LED’s to illuminate the sign and its latest square beam reading light.
