Hello Juha,
While I am currently in the process of integrating the Eurocontrol SSR Code Allocation List into our Topsky setup, I came across two issues:
The plugin seems to ignore any range with an Area definition (e.g. DEPAREA, DESAREA, AREAVIA) even though all areas are defined correctly.
For example: ADESAREA:UK will be ignored while ADES:EG works file. It seems like this is a bug, correct?
Could you please consider adding an option to exclude certain airports from the Mode S area? In Germany for example, all ACCs/UACs generally accept squawk 1000, but some aerodromes don't use squawk 1000 yet due to equipment reasons (e.g. EDDN, EDDK, EDDS etc.). Therefore, I would like to exclude these airports from the Mode S area.
Edit: Apparently, for 1. it's only the case for aircraft still on the ground. For airborne traffic, the areas have been reported to work.
