this post is misleading, that is no ruling AESA has no power to do so. that note is a "friendly" reminder of how things are in spain and always been.
the note comes from a series of public videos that have being seeing on TV of shots in city and public events done via Multirotors.
they are just sorting out the mess with a public "note" if you see the note is not even signed.
this comes because spain is in the work of an RPA legislation and want to avoid any kind of trouble while that gets ready.
they are just trying to stop all those companies lying to the clients saying they have permits to fly anywhere they want.
