+xAh, you're referring to the country-wide class C. Just as on paper charts, we don't explicitly show country-wide airspace in our main map as it's not very useful to do so. However, the airspace data is still present in SkyDemon and you can see it in the virtual radar when you plan your flight.
As someone mentioned, you'll also see it in the airspace stack shown in What's Here but only if the window is high enough, which is dictated by the number of items for inspection on the right.
I absolutely agree, that it makes no sense to show country-wide airspace on the main map.
But in "What's Here" it should nor depend on the number of items if the stack is complete, or not.
The Stack is a great help, to get a fast impression about the airspace structure. Much faster then the textual information on the right. But this only works, if one can rely on it. Why not just scale the Stack, so it will complete fit even in small windows.
The country-wide class C starts at FL 100. But near the Alps its lifted up to FL 130. The border of those areas are not good to see in SD. So every Pilot crossing the Alps VFR will regularly check, if he/she can already climb. What I want to say with that, is that it's not enough to "know" that the FL-100-Ceiling exists. And that it would really be helpful if the Stack would show this in any case.
Not to mention foreign Pilots from other Countries. Germany, Austria, Switzerland, Italy. Sometimes You cross three Countries in a few Minutes. All have different "Ceiling Airspaces". But "Whats Here" will only sometimes show them...
