NEW grouped airspace
complex airspaces are often a combination of different parts (blocks). Due to the airspace file structure each of this part is handled as a separate airspace.
This can be annoying if you want to acknowledge or en/disable such complex structure.
The airspace grouping will combine all airspace parts as one airspace, as long the parts have identical names and types.
The name must be identical in length and upper-/lowercase characters.
Grouping the airspaces can be turned on/off in Setup page 2 "Airspaces".
But in case you need separate acknowledgment of parts of the same airspace it is a better way to give it different names (e.g. Dresden EAST, Dresden WEST).
