I am just trying out the Free Trial of SD.

Here in southern Germany I am unable to see the standard Airspace C starting at FL100.
I can see C starting at FL130 in the alpine area, but not the standard C in the flatlands.

Same goes with airspace E. Visible when the lower limit is off-standard (like 1000ft)
but not when standard (2500 ft).

What am I doing wrong? Thanks a lot!

(and yes, I have well planned a route high enough - currently FL150)

Thank you Tim for this clarification.

Quite frankly, you should "tend to do that". At least with airspace C.

If I am flying VFR in FL120 from Austria to Germany, all well within airspace E, there will be a certain moment when I NEED to descend below FL100 or otherwise I HAVE to contact ATC. SD not showing this imminent airspace violation is - well - ridiculous.
(I tested it myself in simulation mode: Flying FL120 northward - all I get is an infobox "Exited Alpine Areo Class E", when instead, I just entered airspace C.)

Did you never hear any complaints about that? Might just be that all the pilots are still in jail ;-)

No, seriously: could you please consider adding airspace C at FL100 to your data base?

Thanks a lot,
Daniel
