How can i distinguish on the map between "perfect vmc conditions" and "no data available"? In the screenshot there is a rectangular area, that has probably no data. This area, which was in fact not flyable in vmc, is displayed exatly the same way as the area west of the green stripe, which had in fact perfect vmc conditions.

The depiction of "no data available" in Flyable Conditions is the map being a solid translucent red colour. You'll probably see it briefly when you first turn the feature on, before the data has loaded.
It is not possible in Flyable Conditions to have small islands of no data, due to the way the forecast model works.
I agree the abrupt edge of the coloured section in your screenshot is a little unusual, but not exactly unheard of. If you regularly see such an effect feel free to contact customer support with the exact time you saw it, a screenshot, and the information under What's Here (which I believe shows the model information) and we can ask the data provider to check.

Hi Tim,
the screenshot was made on August 17th, 14:29 Z.
I tried a restart of SD, tried different zoom levels and made changes to the route, but the section with no data remained the same.
From my point of view, this is a dangerous bug and needs to be fixed.
Best regards

I can see only two possibilities: a) Weather is changing abruptly over many miles exactly on 48° 00.0 N b) There is a bug in the system
From some decades of real life outdoor experience, i feel free to argue, that a) is quite unlikely. So you are saying the system has no bugs, which again, based on some decades of IT experience, seems to me to be quite unlikely, too.
Wish you happy debugging ;-)

It is not uncommon to see straight lines in the "edges" of bad weather as depicted in Flyable Conditions, I just scrolled around Europe right now and was able to observe them. Why these occur, I cannot say, I presume they're the result of the original satellite imagery and the forecast model processing.
The fact that one of these edges occurred at a latitude grid line makes you think this is a bug in SkyDemon. I disagree; it's inevitable that sometimes these will occur on a grid line.

Tim, Which one is it? sat imagery or forecast modeling? Once you say it has no coverage defined because it's a forecast model, now it's due to sat images. I completely agree that the 'good weather' vs 'we have no clue' areas MUST be easily distinguishable. I can also accept that you have no influence, as the data was like that from the provider. However, you also need to accept that we are not the ones with any knowledge/influence on that provider, but you are.

I used the word and, indicating that I believe it to be a combination of the two. A bank of fog, for instance, can easily have a straight-ish edge as it rolls along the sea or elsewhere. The resolution of the product is fairly coarse so what appears as a straight line (in pixels) would of course not be that straight in reality.
The coverage of Flyable Conditions is most of Europe; if you zoom out you can see the edges. There is currently no such thing as "no data" areas inside that coverage.
Please refer to the user manual if you want more information on the Flyable Conditions feature and how we recommend you use it.

The provider is Meandair and the model is proprietary.
