This route crosses the TMA of Szechin which goes down to 1000ft and is airspace D, thereafter crosses a part which goes down to 1700ft and is airspace C. How can I tell this from the map? I get a hint at the "flight details" tab and at the radar at the bottom, but the lower limit of the areas appears to be displayed incorrectly. 

Edit: it relates to stacked airspaces and the map scale, see images 4 to 6: with the iPhone at 1:350 000, the limit of both parts of the TMA are displayed, at 1:500 000, only the upper TMA is displayed (which is dangerous) and at 1:750 000, only the lower TMA is displayed, which is ok if the route is planned at 2000ft. With the iPad mini, only 1:250 000 displays both parts of the TMA correctly, larger scales display only the upper TMA.
