Under the 'specific' category do I still need training, given that I was flying drones before the rules became applicable?
Any certificates of remote pilots’ competency issued by national authorities will remain valid until 1 January 2022, after which your National Aviation Authority will have to convert your national certificate(s) to new one(s) that comply with this Regulation.
Whether or not you have to undergo more training after that date will depend on the conversion process that your National Aviation Authority decides to put in place.
As of 31 December 2020, if you do not have a national certificate for your remote pilot competency, you will have to undergo the required competency training as required for the ‘open’ category.
Regulatory reference: Article 21 and Annex part A (UAS.OPEN.020) and (UAS.OPEN.040) of EU Regulation 2019/947.
