LXNav screens (LX9000, LX9070, etc) and polarised sunglasses

[[email protected]]

Good evening all,

Has anyone experienced any problems with polarised sunglasses and LXNav PNA's? If so, could you kindly advise:
- The model number
- The installed orientation, and
- What plane was the screen polarised in, horizontal or vertical?

Many thanks!

I had a problem with a CAI 302.Â* It seems that in a certain batch of
production, the screens were installed 90 degrees to the required
orientation.Â* With that, I had to raise my polarized glasses or tip my
head to the side to read the instrument.Â* It was doable, but very annoying.

I have not heard of any problems with the LX9050, LX9000, LX9070.

Back in the day (and that day was 15 years ago), I sent my 302 back in for a free screen swap to get polarizing the right way. Someone somewhere probably has some "right-way" screens sitting in a dusty old box.

Didn't know the 302 was an option with LX90x0. The V8/80 is probably a better choice, certainly more contemporary.
Casey: My now ancient fix for non-standard polarisation angle issues was to stop wearing polarised glasses.

Thank you all

Jim: I’m attempting the reverse. Haze domes and cloud detail have been evading me. Something I’d like to change by going polarized.

I have used my LX9050 with polarized RayBans. No issues. The only thing I couldn't see was the Trig transponder screen. It's polarized the wrong way, I guess.

Old wisdom is that you never fly with polarised glasses because sun's reflection from other aircraft is essentially polarised to one direction and will be invisible trough polarised lens. Seeing cloud outline far away, haze domes etc. requires good contrast, usually brownish tint is best. I use Zeiss Skylet sunglass lenses which give amazing color reproduction AND contrast (very difficult to do both). I think they are optimal for gliding (and quite expensive, unfortunately). Absolutely no problems with any glider displays.
