When flying through Emmen Airspace, the tower frequency of Emmen was shown on the Pilot Log. There should also be additionally the Info frequency 134.130.

See Swiss ICAO map

The frequency is used to check which CTR/TMA of the airports Emmen, Buochs and Alpnach are active.

Best regards,

Alain

We are unable to associate more than one frequency with a piece of airspace, so that's the way to get to it in SkyDemon at the moment.
