Ordinary strobes are, as has been agreed, not powerful enough to make
much of a contribution to visibility. However, a former glider pilot and
electronic engineer, Phil Manning, is developing an LED flash to perform
the same function. The "flashes" are of much higher intensity but of
much shorter duration than that emitted from a strobe so current
drainage is reasonable. Furthermore, as this is a cold light, the
casings can be moulded to conform with the glider thereby reducing any
extra drag. I suggest that anyone interested in his work contact him
directly at;-

Dick Johnson wrote one some time back, but I don't remember which issue.

Sorry. However, I believe he concluded that the distance at which the

strobe was noticeable during the day was so relatively short that there

was minimal benefit to the installation.

Anyone remember/know what issue(s) that was in? I'm researching
collision avoidance stuff (again, still . . )

(Boy, do I wish there was a good INDEX to Soaring! I've got every
copy since 1966 and a few going back to 1937, making a fantastic
resource
that's
darn near unusuable because there are no complete indices (and the few
that
were printed back in the seventies and eighties are poorly organized
. .))
