GM1 to AMC1 Article 14(6) Registration of UAS operators and ‘certified’ UAS
UAS OPERATOR REGISTRATION NUMBER An example of a UAS operator registration number as defined in point (a) of AMC1 Article 14(6) Registration of UAS operators and ‘certified’ UAS is ‘FIN87astrdge12k8’, where: ‘FIN’ is the ISO 3166 Alpha-3 code of Finland; ‘87astrdge12k’ is an example of the twelve (12) alphanumerics, as defined in point (a)(2) of AMC1 Article 14(6); and ‘8’ is the checksum, i.e. the result of the application of the Luhn-mod-36 algorithm to the fifteen (15) alphanumerics that result from the concatenation of the twelve (12) alphanumerics of the UAS operator registration number and the three (3) randomly generated alphanumerics (‘secret digits’, as defined in point (b) of AMC1 Article 14(6)): ‘87astrdge12kxyz’. An example of the full registration string, as defined in point (e) of AMC1 Article 14(6), to be provided by a Member State, is ‘FIN87astrdge12k8-xyz’, where: ‘FIN87astrdge12k8’ is the UAS operator registration number; and ‘xyz’ is an example of the three (3) randomly generated ‘secret digits’. The UAS operator must upload the UAS registration number and the three (3) ‘secret digits’ into the remote identification system of the UAS, if available, or into the electronic-identification system, if required by the geographical zone. The UAS operator should not share with anybody the three (3) ‘secret digits’ that are used to enhance the protection of the UAS operator registration number from being illegally uploaded into a UA.
