I would like to see the experiment method described in detail. While I have not conducted any tests on high visibility colors, I can tell you they work on my eyes for roadside workers, construction crews, hunters, and they single glider I have seen with the day-glo orange, all the above were highly visible. I also know from merging and formation flying the aircraft with red really stood out.

As a former engineer I will gladly accept well designed test results. But if you do not publish the experiment method, in detail, then the conclusion is suspect as it has not undergone peer review. Having said that, I am depending on eyes, Flarm and LED strobe in my bird.


The studies on glider conspicuity I've seen were all performed in Europe. It would be interesting to see the results of a similar study in an area like Nephi, or Hobbs, or Uvalde, or Minden on a typical summer soaring day. I've flown at the latter three sites but not at Nephi.
