What can I do if I don’t have a class ID? Grace period until 31 December 2022. In the future, drones will be provided with a so-called class identification label, which certifies what technical conditions the given device meets. Depending on the class identification label (CIL) of the device, it determines in which subcategories the operations within the “open” category can be performed. A drone can have multiple CILs, so they can be used in either two or, in some cases, in all three subcategories.
