Is it possible to get a VFR clearance into that airspace?

Yep, it's class C not A or B.

Yes, but authorities don't always allow transits of such airspace in every country, so I had to ask.

The main reason we omit such large country-wide airspaces at the moment is that they slow down the system. Not when drawing on the map (they are typically excluded from the map anyway) but as you fly, we need to check every second whether (and how) your flight intersects with these airspaces which typically comprise thousands of coordinates.

Having written the odd program myself, I appreciate what you say. However, rarely is the customer interested in the woes of the programmer. What the customer needs is a solution. How? "You'll figure it out", is what I heard most often.

Very helpful. I am simply pointing out that if I implement this, the experience will get worse for just about every customer. This helps to explain why I have not implemented it.

I wasn't trying to be helpful just pointing out the expectation of your customers.

All I am saying is that airspace that requires an entry clearance is something most SD users expect to be warned about. Even if that airspace overlies an entire country at 10,000 feet (that's a reasonable VFR altitude, particularly in mountainous terrain). Climbing above 10,000 feet or crossing the German border at an altitude above 10,000 feet would have me in violation.

So if the standard way of checking for airspaces in SD isn't good enough for this, someone needs to be creative.

As you did not find Chrises "You'll figure it out" very helpful:

Obviously your software does not have any issues with thousands of airspaces in Europa that are currently NOT close to the coordinates of the airplane. I assume your software uses an algorithm that removes these airspaces in an initial step before checking for any airspace intrusions with the relevant (in close proximity) airspaces.

So why not split up the huge class C airspace in Germany in pre processing (NOT on the device)?
By breaking up these airspaces in maybe a frew dozen sub areas your software performance might be up again.

Thank you Chris for pointing this out again!

I can only speak for myself (as a not-yet customer):
As long as SD only warns me about 95% of the relevant airspaces I will stick to my current solution and safe my money.

Hi,

the Situation presented by Daniel_KDF is sometimes a big problem. A problem that can ruin you. As a matter of fact I witnessed exactly what Daniel mentioned, on the Frequency of Munich FIS. Some Guy flew northbound in the area of Kempten, where the Alpine Class E Airspace ends. That pilot flew right into the C Class Airspace. The nice Lady on the Radio advised him on that and that he had do descent at once. It was a very hot day and everyone was flying very high that day. 
I am from southern Germany and was trained in that area north of the Alps, so I'm well aware of that airspace stepdown. You Can "see" it in the printed map and also in Skydemon, but only if you are aware of this circumstance.
You can produce the same problematic Situation if you fly from Austria to Germany in FL130 or higher, northbound. Again you will fly right into C airspace without warning. 
Skydemon does display the TRA's above FL100, for example EDR207B which is north of Kempten and begins at FL100.

I think the poses a big problem for pilots who are not aware of this airspace situation and Skydemon should warn you in the same trustworthy manner it always does.

Hello,

just a remark from another german customer who flies quite often in the Alps region.

I agree to the other guys explaining the problem with necessary descent from FL120 to below FL100 leaving the Alps E airspace.
I also would appreciate it if SD would warn if the plane enters a restricted/controlled airspace.

Of course preflight preparation should make aware of that, but neithertheless I think it would be great feature if SD could warn before maybe entering illegally another airspace.

But I also agree - if a country wide airspace would be bad for the performance / stability, than don't do it ;-)
