Yes, but it works just fine with my polarized glasses in the vertical mode. So I made a bracket to hold it at the edge of the glareshield to the left of center.



Since the device and display are rotatable in increments of 90 degrees, and since all LCD displays I've seen are polarized in one plane or another, Butterfly had to pick one knowing full well that it would please some and offend others of the polarized sun glassed crowd. No way for them to win!

Well, not sure I entirely agree with that. I am pretty sure there are alternate solutions to that though I am not an expert by any stretch of imagination:

With that said, note that all their literature and pictures on their docs/website show the display mounted in horizontal layout which is orientation that does NOT work. This is opposite of how they actually installed the polarizer filter and seems more like a bug advertised as a feature!

Recently, I tried buy non-polarized clip-on or flip-up sunglasses for my
prescription glasses. There hundreds, but all were polarized. Does
anyone know where non-polarized clip-ons or flip-ups can be found?

I bought a pair (non polarized) in NZ a few years ago.

Any reputable optometrist should be able to put non polarized lenses in
your clipon glasses - when I bought my first pair of corrective glasses
the clipons that came by default were polarized, i asked for them to be
replaced with non polarized lenses, it added the benefit of choosing the
tint I wanted. Additionally I would recommend getting corrective
sunglasses instead of clipons for your regular glasses.. I found the
clipons let in too much light between the tinted lens and the corrective
lens. When buying dedicated prescription sunglasses you can choose non
polarized lens.

So- I lose the polarization which I find is a big help in cloud reading, so that I can read a Flarm display.
Not the best trade off for this pilot.

I did not realize polarized glasses helped with cloud reading. During
training we were told not to purchase polarized glasses as it may
produce blind spots due to refraction issues/imperfect canopies etc...
Since then I've always been under the (apparently mistaken)impression
that most pilots flew with non-polarized glasses, and have avoided
purchasing anything with polarization. I'll have to give polarized
lenses a try see if they help! I much rather see clearly outside than
any instruments in the cockpit.

There are those who swear by polarized glasses (like myself) and those who don't. I only fly with polarized glasses as I find them improving visibility of clouds, haze domes AND other gliders significantly, as well as reducing canopy reflections. I suspect those who claim otherwise didn't give them a try. I definitely not intend to give up my polarized glasses so I can read the flarm display. The solution as I suggested earlier is to rotate the display or switch to the panel mount display. Perhaps putting more pressure on the butterfly folks to address this issue will help.

Reflected light can get polarized, and then filtered totally by lenses
with 90 degree difference in polarization angle. Therefore using
polarized lenses is not a good idea IMHO.

Luke, I bet then that no one has told you of the special "thermal coloring glasses" (works just like in Condor).

I agree with Morteza, the polarizer filter should have match the most common layout, which is most likely horizontal. Or they could have provided 2 versions. Perhaps if we put more pressure they will. However with some effort you will most likely find a place to mount it vertically as I did, or switch to the in panel display if you have space, as it is polarized correctly and has louder volume.
