I did noticed that it's missing some information and frequency at some controlled TMA-area in Sweden.
We have some area or "sector" that are shared between two control units.
When one control unit is closed then the other one takes over that sector.
‌

On papermapthere is written like:

"Sector Klippan"

Open : Ängelholm 132,450

Closed: Ljungbyhed 129,550

 

In SDthis Sector only show the frequency of when it's Closed.

Itshould show the frequency of when it's Open instead, which is more common and importantto use like the Swedish AIP: ES_ENR_2_1_en.pdf says.
So no need for SD to know if it's open or closed. Just show the pilot both frequency with priority Open / Closed.

I will consult with my colleague on our best approach to this. SkyDemon isn't really designed with a mapping of multiple frequencies to one piece of airspace in mind.
