Hi @MikeRaven
You can read our Article 16 Operational Authorisation here: article16.fpv.uk
Section 3.7 of the Article 16 Operational Authorisation is entitled ‘Location(s) of Operation’ and starts ‘This authorisation may be used throughout the United Kingdom’.
It is not valid outside of the UK.
There isn’t an ‘EU drone licence’. You just need to register and get an Operator ID (which is free), and do multiple-choice quiz and get a Flyer ID (which is also free). Then you must display the Operator ID on your aircraft.
You can do that in any EU country but I would recommend Alpha Tango - the French system.
This thread walks you through the process: Operator vs Flyer in Europe
I hope that helps. Any further questions please let me know.
