Why change from electrical systems to saf-Tglo®?

Airlines have previously had issues with electrical systems as they are prone to failure or complications, which can result in aircraft being grounded. Reliability is a major requirement when deciding which emergency exit system to use. If saf-Tglo® is there, it works, and requires no maintenance or costly parts.

Why change from seat-mounted systems?

Seat-mounted systems were a response to floor-mounted electrical systems that failed because of excessive traffic or ‘hard knocks'. saf-Tglo® eliminates this issue: our sealed saf-Tglo® system has a robust exterior which has been proven to withstand footfall and trolley traffic. Because saf-Tglo® is a twin-track system, when the carpet needs replacing you only have to replace the section between the two strips of saf-Tglo®. Once installed, saf-Tglo® is durable and cost-effective – saving both time and money.

Why change from other photoluminscent systems?

STG Aerospace pioneered saf-Tglo® in 1995. STG Aerospace is the the world’s expert in the application of photoluminescent emergency lighting in the aviation market. STG Aerospace is the only manufacturer in aviation of photoluminescent systems designed and produced ‘in-house’. STG Aerospace's experts provide honest technical advice to support all customer requirements.  

STG Aerospace provides honest technical advice. We are proud to offer support from initial enquiry through to post-installation. Please contact us if you require support.

saf-Tglo® is simply cut to length and installed using the same double-sided tape that is used to install the carpets.

There are some simple rules that must be followed:

1. The photoluminescent strips must be installed at floor level along both sides of the main passenger aisle(s) with no significant breaks in the lines.
2. The saf-Tglo® system must be combined with the more typical battery-powered low- level exit markers to create a so-called 'hybrid' system.
3. The saf-Tglo® system is mounted on the floor below the seat armrests or adjacent to the cabin structure (galleys, lavatories, cabinets, etc.).
4. At each over-wing exit, an outboard spur must be installed to provide additional guidance to the evacuating passengers.

You will need to perform a lighting check to ensure that cabin lighting on your aircraft is sufficient to charge the saf-Tglo®. We have designed the STC so that the minimum lighting level is easy to achieve with even the oldest fluorescent lighting systems.

To operate a saf-Tglo® system you need to set the cabin lights to bright and perform a system charge at the start of the day. The charge time depends on the aircraft type. Typically it is undertaken while the aircraft is being prepared for the day's operations and does not impact on the operational timings as the charge times are so short.

Unlike electrical systems, saf-Tglo® does not require any power supply. This reduces the amount of battery packs required on board and the associated cost to the enviroment. As a company, we reduce the amount of waste by re-using components where we can and recycle what we are able to.

The saf-Tglo® system charges by any light source: cabin, daylight, etc. Once all light sources have been removed, the saf-Tglo® discharges (glows) over many hours to indicate the aisle path in any dark cabin emergency situation.

With up to 300 colours available as well as our Colourmatch system, STG Aerospace will be able to find the colour for your cabin interior. However, we cannot supply in red or black as photoluminescence will not charge in these colours.

Yes, we now offer PatternMatch™, a unique pattern matching innovation. This has been developed in response to demands from customers for whom interior design is a key feature. If you are interested in this service, please contact us. We are able to provide a sample of PatternMatch™ if you can supply a small amount of the carpet used on board your aircraft.
