STG Aerospace has designed, developed and patented a saf-Tsign product in response to a request from its long-standing client Icelandair.
The product has been introduced to help the airline upgrade some dated Passenger Service Units (PSUs), complete with a switchable Wi-Fi sign. Icelandair was one of the first carriers to roll out high-speed Wi-Fi connectivity across its entire fleet and turned to STG to effectively communicate this enhancement on its fleet of Boeing 757 aircraft.
Through a 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, so the sign is 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, said: “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, added: “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.”
