I've noticed that some of the TMA frequencies in Switzerland does not match with the correct ATC-unit. For example, around Zurich, SD mentions "Zurich Information", but this is only the FIS-frequency and they can't give clearances by themselves. For TMA crossings "Zurich Terminal" is the correct ATC-unit to contact in TMA-airspace around Zurich for VFR-traffic in class C. For crossings within the non-TMA and non-CTR airspaces (class C and D), "Zurich Delta" is the correct ATC-unit. They give for example clearances to cross corridors and in general class C airspace above FL100/FL130.

In Germany, the non-CTR airspaces in class D and C doesn't have published frequencies for VFR-charts at all, but they are mentioned within the IFR-arrival/departure charts as Radar frequency. For example around Suttgart, this would be "Langen Radar" on 125,050 or 119,200 and around Cologne/Bonn, this would be also "Langen Radar", but now on 135,350. The problem here is the German ATC-company "DFS", which want to force VFR-pilots to contact FIS first prior to cross airspace class C or D.

Are there any updates regarding this topic?

Regarding Switzerland: The frequencies for General Class C in Switzerland are also still missing, this should be "Geneva Delta" on 119.175 in the Geneva airspace and "Zurich Delta" on 119.225 in the Zurich airspace (same boundaries as FIS). FIS is only responsible for airspace E and G in Switzerland, for C (non-TMA) it is Delta. This is also described in the AIP ENR 2.1.

Furthermore, there is an issue with the "Information" frequency for LSME, LSZC and LSMA. This just an information frequency for airspace activation, just like an ATIS, which tells you what airspace is active or not. You cannot make a call on that frequency and its certainly not an AFIS. It's now mentioned as "Buochs" for LSZC, "Emmen Information" for LSME and "Alpnach Information" for LSMA, but it should be called "Airspace Information" or something similar, since it is one frequency for all named aerodromes. This takes me to the next error: "Kägiswil Information". There is not an AFIS-frequency for LSPG. Before departure, pilots should monitor the airspace activation-frequency to check if the airspace of Alpnach is active or not, and then the pilot should call Alpnach Tower for clearance OR make blind-calls on the Alpnach Tower frequency for Kägiswil. In my opinion, "Kägiswil" 128.475 would be sufficient for LSPG.

Last but not least, Meiringen (LSMM) and Dubendorf (LSMD) have only "Tower" as radio-callsign, which should be "Meiringen Tower" and "Dubendorf Tower" of course.
