Had a conversation on the Skyview weather area, like how big an area can you see weather? I thought you could see the whole USA (when airborne of course), my friend thought you could only see a small circle around you. Who is correct?

The whole USA. I think more detail is available nearby. I think you will see an age of data for regional and ConUSA. It's in the book.

There are some EFIS systems that only show the local data, but SkyView is not one of those.
NEXRAD Radar Imagery
NEXRAD radar transmits short high-frequency beams of radio energy into the atmosphere from
the ground at various angles and receives reflections of that energy back at the original site.
The return signal is then amplified, processed, and colorized for easy interpretation. Based on
the time it takes to receive the reflected energy, the radar data product is able to convey the
approximate location and density of precipitation at a specific location. This is then depicted
graphically on the SkyView map page.
NEXRAD radar provides high resolution local regional imagery and lower resolution imagery
that covers the entire continental US (CONUS). The FAA’s ADS-B system transmits both of these
periodically, limiting the high resolution regional weather imagery to your locale to preserve
available ADS-B data link bandwidth. SkyView presents all of this data seamlessly.

From above:
You can get the lower resolution for anyplace in the USA and zoom in and see it, but this does not make it as high resolution as the areas near you. It's all relative though, the "low" resolution is still pretty good and given that it would take at least an hour in a a fast RV to get to the low resolution area, by the time you've flown near it you are now getting it as high resolution.

Thanks, that explains it well, I understand what it does now.
