Hello Ian I can provide you with test results. Two years ago Schleicher asked me to try the new LCD lights on my on my ASH 25. We integrated a double row of flashing LCDs in the leading edge of both winglets and tested the effectiveness in bright Australian sunlight. The results were not as good as expected. I reported back that the light intensity needs to be significantly increased in order to provide any major safety benefit. However, in overcast conditions (or while flying under a cloud street) these flashing LCDs allow the glider to be detected much easier.
Please feel free to contact me off line for further details. Off to Mt. Beauty now!!! Bernard Eckey FUTURE AVIATION PTY.

Subject: Re: [Aus-soaring] Keeping Visible I can remember talking with the late Mike Valentine about the concept of using strobe lights on aircraft in general. His comment was that a single non flashing light was more effective than a strobe. This was quite easily demonstrated with aircraft flying with their landing lights on were much easier to see from much further away than ones just with the strobe on. Try it sometime, particularly around a GA airport. I believe that with the new LCD lights, which draw low power and a fixed to a wing tip would be much more effective than a strobe. They would be visible when turning and or head on. I read a safety article in US Soaring mag once, that pointed out the following. And take note. The letter o at arms length, represents the front on fuselage profile of a glider approximately 200 metres away. Try it. A fixed beam of light from a wing tip would highlight this dot much quicker. As we scan the sky we can very easily miss the flash of a strobe. Finally with paint, when the VMFG operated Kookaburras,the lower surface of one of our Long Wing Kookas was painted orange, the other one was white. Even I can remember the orange one was much easier to see in any sort of sky. 3 of my gliders have darker lower fuselages, orange and blue under white and even this stands out better than one colour. The early PIK 20 came with optional White, Yellow, and even Green finishes. The only trouble with the green one was, when flying in the British Nationals and landing out , the retrieve tug couldn't find it from the air and it very quickly had orange stripes painted on.
