Lufthansa Technik receives approval for new photoluminescent exit signs

Lufthansa Technik AG in Hamburg has received approval across all aircraft types for a new generation of photoluminescent exit signs. With immediate effect the existing maintenance-intensive and non-environmentally-friendly exit signs at the flexible curtains in the cabin can be replaced by the Lufthansa Technik GuideU material, which is already used for emergency floor path marking. Regular replacement of signs for reasons of aging as has been the case to date is now history thanks to a so-called “Multitype STC”, an aircraft manufacturer and type-spanning approval for the new material. The exit sign made from the self-illuminating, aging-resistant and completely maintenance-free GuideU material simply has to be installed once directly at the aircraft manufacturer or as part of routine maintenance work. The signs previously had to be replaced after seven years at the latest. 30 different language variants of the bilingual signs are already available now, while others are in progress. The signs can be replaced as part of smaller maintenance activities during daily aircraft operation.
