I flew on 4/7. I connected my Oudie N to by iPhone using the phone as a hotspot. I had Navigator running on my phone also. Less than an hour into the flight the Skysight weather disappeared from the Oudie. Soon after it disappeared from my phone too.

It was a short flight as I didn't find lift. On the ground I had to restart the Oudie to get Skysight weather to come back.

I flew today and saw the Skysight information disappear about 1 hour from take off on both my Oudie N and on Navigator on my phone. Has any progress been made on the issue? When do you expect this to be resolved?

Thanks,

Hi Doug,

We are treating this as a feature request. The SkySight weather maps are not loaded in advance at the moment, they expect to be downloaded on the fly while flying.

We will let you know when it is done, but it won't be in April.

Although the subject is skysight, I noted Naviter response to your Polarized question.
I respectfully disagree with Naviter response. I’ve been flying for over 20 years with polarized sunglasses and had no issues with any other screen (unless I tilt my head significantly). You will only see black screen if your sunglasses polarization is
wrong or the screen polarization is wrong. If both polarized correctly, they will not cancel each other. You may want to try another polarized glasses, and if the issue persists, then your Oudie has wrong polarization. You may need to rotate your display
as you suggested.
I always fly with polarized glasses as it enhances wisps and faint clouds.

For displays such as on Oudie N, it is a property of the screen type that the display is polarized (at an angle chosen by the instrument manufacturer). For displays that are only put into the panel one way, the manufacturer can orient it such that
polarized sunglasses will not diminish the brightness (due to polarization) unless the pilot tilts his/her head significantly (as Ramy notes). (Note: sunglasses are polarized vertically, which cuts out horizontally polarized reflections, such as off the
water.) For instruments that are made to operate in vertical or horizontal (portrait or landscape) orientation, the manufacturer is faced with a choice - if the polarization is set at either vertical or horizontal, the display will appear fine in one
orientation and black in the other, (and varying degrees of darkness in between) through polarized sunglasses (unpolarized sunglasses have no effect). So, a compromise is to (optimally) set the polarization of the screen at 45 degrees. At 45 degrees,
this will diminish the brightness by 50% for either instrument orientation (Transmitted intensity = incident intensity*cos^2(angle of polarization), but it will be readable with sunglasses, polarized or not. This is in addition to the reduction in
brightness by the sunglasses due to lens tint.

In general, as Ramy says, polarized sunglasses will enhance sharpness. On the other hand, the military does not issue polarized sunglasses for pilots (according to my source) because it can eliminate the glare/sun flash off another airplane fuselages or
wings - the same goes for glider pilots trying to spot other gliders in the area. It becomes a matter of choice for glider pilots as to which is more important. My experience is that I stopped using polarized sunglasses due to instrument display
obscuration due to polarization since so many of mine can be oriented in the portrait or landscape position. My CN flight computer, which can orient either portrait or landscape, appears to be at about a 70 degree offset for output and I had to tilt my
head slightly to read it when in portrait mode. I have experienced the same on other instruments that can go portrait or landscape for orientation, but not on instruments that have only one display orientation. Also, I do find it easier to find other
gliders at a distance from their glint with non polarized sunglasses.

I will suggest that with greater use of FLARM, finding other gliders has become easier, and with ADS-B IN/OUT even easier. But visual identification is still paramount.
