LED lighting technology has come a long way in the past few years and is still rapidly improving. Looking at the specifications on website http://www.aeroleds.com/ the average current draw at about 1 Ampere per light is still rather large for a glider. I suspect the efficiency will continue to improve to the point where they will be a viable option, perhaps glider manufacturers would then include them in their design. BTW some of the cyclists LED lights are extremely bright especially when flashing but full daylight is hard to compete with!

Re: [Aus-soaring] Glider visibility-UK-BGA
John, Your last 7 words sum the situation up nicely but possibly some genius may be able to turn this to advantage. As I recall the original research (and of course as we know from our own experience), the only useful positive finding was that the reflected flash of sunlight off a highly polished wing was visible for miles Unfortunately this situation really only occurred when a glider was circling. So it is not so much a matter of Mandrake and smoke and mirrors, but more about mirrors! As John McFarlane rightly notes, everything else (at the time), was basically useless for an aircraft that could be any colour you like, as long as that colour was white! It is nice to see the CAA giving it a go. Does anybody know what the allocated budget for the program is? In the meantime we are left with lookout, lookout, lookout, and to a lesser (but invaluable) extent Flarm.

Re: [Aus-soaring] Glider visibility-UK-BGA
Hey Bernard
I don't use them all the time because they only stand out while cruising under
a cloudstreet or in slightly
overcast conditions. In bright daylight they are less effective but I still
turn them on while flying in areas
of high traffic density.
Isn’t that a bit selective... bit like putting seat belts on in heavy traffic !

My only additional thought was whether it would be worth connecting the LED
strobes up to be triggered by the flarm such that when the flarm alarm sounds
the strobes start going (in addition to a manual switch).
A different line of thought, that would up the fun quotient considerably, would
be a modern version of the RP-63 'Pinball' (google it). Connect up a little
box simialr to flarm that works out line of fire in two aircraft and then go
dog fighting. The strobes go off signifying hits. (The RP-63 was a development
of the Bell P-63 King Cobra in WW2 and was used to train bomber gunners. It
had a strobe light in the nose in lieu of the cannon. The strobe would light
up signifying hits from the gunners.)

LED strobes are increasingly common in the amateur-built arena. The desire to
save weight means it's pretty unusual to install a strobe which requires a
heavy power box these days.

Hi Anthony and others!
You might recall that I have embedded a row of LED strobe lights into the
leading edge of the winglets
on my ASH 25. It was a trail for Schleicher and happend about four or five
years ago.

The very latest generation of LED strobes are by far more powerful and a lot
more effective. They will
momentarily blind you if you look directly into them - just as conventional
strobes do. The relatively
narrow beam remains a problem but this can be overcome by embedding several
rows of LED lights
into the leading edge of the fin. This option is now available on the latest
breed of Schleicher ships.
The beauty is that there are no aerodynamic penalties at all.
Kind regards to all

Re: [Aus-soaring] Glider visibility-UK-BGA
Given they found this didn't work in UK conditions last time - RAF investigation, probably not. In some light conditions, the coloured wing tips shortened the effective visible wingspan making things worse - it was like camouflage !
