Swiss Official ICAO Chart Overlay

In Switzerland, ATC and other pilots, strongly prefer to only ever use names of places that are listed on the official ICAO chart.

SkyDemon has a couple of issues:

1) There are places listed in SkyDemon that are not on the ICAO chart.
2) There are places on the ICAO chart _not_ listed on SkyDemon.

The first is a larger problem, since a pilot may be tempted to report their position using a name not listed on the ICAO chart, and the ATC or other pilots in the area would have no idea.

What kinds of workarounds are available to alleviate this issue?

I do not believe we have ever received any such "list" because there is no official list. They are not aeronautical data. The problem is, it seems ATC in Switzerland often use the same ICAO chart, and have adopted the towns listed on that chart as unofficial VRPs.

There is an implication in the last two posts that we possess tools to pick and choose which towns are selected in our maps at individual zoom levels. We do not. Could we develop those tools? Sure, but at present, Switzerland is the only country in which this seems to be an issue, and even then, we do not hear about it very often. Do ensure you have contacted customer support to let them know about this, so we can ensure that we record your desire for our chart to include those towns.

I appreciate this is more likely to be a problem for new pilots who have probably trained with the ICAO chart and have not yet moved on to charts from other providers, with the inherent differences therein.

I see, I was just referencing what other users had posted in this forum on the topic before me.

Indeed, hence it's also not just a problem for new pilots, but also pilots unfamiliar with Swiss airspace.

That is insightful and surprising,I did indeed expect that you guys had a 'tight' grip on all chart data including towns etc. but it makes sense why you wouldn't want to get into that.

Will do so!
