Lufthansa Technik approved for photoluminescent exit signs

Lufthansa Technik AG has received approval across all aircraft types for a new generation of photoluminescent exit signs.

The existing 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,” said a release from Lufthansa Technik. “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.”

The GuideU system meets demands for environmental protection as well as zero maintenance, says Torben Biehl, Head of Product Development for GuideU at Lufthansa Technik.

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