For Switzerland, many VFR reporting points and VAC map locations used by ATC are missing. Just two examples:
When flying to Locarno, Arbedo is an important VFR reporting point. Mezzo too. ATC will ask you to report Arbedo or Mezzo all the time.
When flying to Lugano, for example after a crossing of the Locarno airspace, there is Mezzo again. M. Ceneri is also popular to be used by ATC.
There is of course an easy workaround: 'Locarno Tower, Mezzo is not on my map, request different reporting point.' It has been a problem for a long time that local ATCOs expect pilots to have the same level of familiarity with their ATC area.
I assume that these reporting points and map locations are not actual aeronautical data. Is that correct?
