EU certificate of competency
The operation of a drone in the ‘open’ operation category is subject to different conditions as regards the qualification of the pilot, depending on the sub-category (A1, A2, A3). If you do not know which subcategory is relevant for you, you can find this information here.

For operations in sub-categories A1 and A3, only an EU certificate of competency is required; further information concerning qualification can be found here. This certificate will be issued after successfully completing an online training course as well as an online theory test.
