Since January 2021, only the new EU drone pilot licences have been issued. These include the EU Certificate of Competence A1/A3 and the EU Remote Pilot Certificate A2.
As soon as a drone is operated with more than 250g, at least the small drone licence (EU proof of competence A1/A3) is required for the drone pilot.
For drones with a take-off weight of less than 250g, we also recommend obtaining a small drone pilot's licence from the Federal Aviation Office. This provides you with basic knowledge about how drones work and how to operate them.
