The VACs overlays are still available at the smaller airfields like LSGE, LSGL etc.

Does anybody have an explenation why?

Thanks for feedbacks

This is the answer I got from SkyDemon:

The Swiss Skyguide VFR Manual is updated regularly throughout the year, and with each update the plates must go through a georeferencing process to enable them to be overlaid on the map in SkyDemon. Unfortunately the release of these latest documents happened outside of weekday office hours, hence the delay in processing. The documents have now been georeferenced, and are available as an overlay, and we will be looking into ways to avoid this kind of delay in the future.

--> that's it! Thanks to SkyDemon!
