Lufthansa Technik receives STC for photoluminescent exit signs


Lufthansa Technik AG in Hamburg has received approval across all aircraft types for a new generation of photoluminescent exit signs. The signs make use of the company’s GuideU material, a self-illuminating, ageing-resistant and maintenance-free material, which is already used for emergency floor path marking.

Lufthansa Technik received a so-called ‘Multitype STC’, an aircraft manufacturer and type-spanning approval for the new material. The GuideU material simply has to be installed directly during assembly at the aircraft manufacturer or as part of routine maintenance work.

“The new exit sign extends the product range of our GuideU system and allows us to fulfill the strictest demands for environmental protection as well as zero-maintenance,” stated Torben Biehl, head of product development for GuideU at Lufthansa Technik. The new system is already being used ex factory by Airbus. “We have made great progress in recent years in optimizing GuideU, which is now translating into additional potential applications.”

30 different language variants of the bilingual signs are available, while others are in progress. The signs can be replaced as part of smaller maintenance activities during daily aircraft operation.
