FAQ n.135904

Only drones compliant to Regulation (EU) 2019/945 (R945)  are safe and therefore authorised to be operated in the open category (unless the drone in privately built, please see the related FAQ). If you operate a drone in the open category without a class identification label or if it is not compliant with R945 you may expose other people to risk and you may be persecuted by the law. In order to obtain reasonable confidence that the drone you are using is compliant, you must apply the measures described in the FAQ above.
