Hi @Kostis-Prassas, see this and this post for more info.

Hi @Ondřej-Šutera , is there any update on this maybe? I believe it is a major issue for the paragliding community. Another alternative would be OSM as long as ODbL is not breached. Tags sport=paragliding and free_flying:site=takeoff are normally used by the PG community, although coverage may not be 100% guaranteed. However, it is still growing and allows users to easily add new locations. Thanks!
