STG Aerospace’s saf-Tglo photoluminescent system, SuperSeal UltraLite (SSUL), has received FAA and European Aviation Safety Agency (EASA) certification for Airbus A320 family aircraft. Following certification, A320 operators are able to upgrade the SSUL emergency floor path marking system to the latest version.

STG Aerospace said saf-Tglo, first launched in 1995, stores and simultaneously emits light and marks the way to the emergency exits after a short charging period. It requires no power source and “features a unique fully sealed design that eliminates fluid ingress and can reduce maintenance costs by up to 80% compared to other systems.”

STG Aerospace said saf-Tglo has been installed on more than 10,000 aircraft operating for over 300 airlines.
