+x C82R - 1/2/2022 10:20:31 AMI'm a PPL instructor in France.A French regulation makes it mandatory to overfly cities and towns at a minimum height depending on the size of the town.The official regulation (arreté de 1957) says that the size of the town are shown on the IGN (Institut Geographique National) 1/500000 map.So I must in practice teach navigation with that IGN map as it is the only source of information available.As it is not available in Skydemon I just cannot recommend Skydemon to my students, and they go for SDVFR or Flymate instead. It's a shame as Skydemon is I think the best VFR navigation app. Once they get used to another app, they won't change.

It will be a special piece of software for France: i.e. in German ICAO charts, towns are classified by the number of inhabitants and there is no such special regulation.
+x C82R - 1/2/2022 8:45:14 PMIt's the map I was talking about. The 1/500000 IGN ICAO Map. It is only available from IGN. The official size of the towns are nowhere else available. You can freely access to the map through https://www.geoportail.gouv.fr/.IGN is the sole ICAO maps publisher to provide the information. Without the 1/500000 IGN ICAO map you just can't make sure that you are not braking the rule when overflying a town below 5000ft AGL.
