AMC1 Article 14(6)Registration of UAS operators and ‘certified’ UAS

UAS OPERATOR REGISTRATION NUMBER

(a)The unique UAS operator digital registration number that is issued by the Member States should consist of sixteen (16) alphanumerics in total, arranged as follows:

(1)the first three (3) alphanumerics (upper-case only) corresponding to the ISO 3166 Alpha-3 code of the Member State of registration;

(2)followed by twelve (12) randomly generated characters that consist of alphanumerics (lower-case only); and

(3)one (1) character corresponding to the checksum that is generated in line with point (c).

(b)The Member States should randomly generate three (3) additional alphanumerics (lower-case only) called ‘secret digits’.

(c)The Member States should generate a checksum by applying the Luhn-mod-36 algorithm to the fifteen (15) alphanumerics that result from the concatenation, in the following order, of:

(1)the twelve (12) alphanumerics of the UAS operator registration number defined in point (a)(2); and

(2)the three (3) randomly generated ‘secret digits’ that are defined in point (b).

(d)For the Luhn-mod-36 algorithm, the mapping of the alphanumerics to the code-points should start with digits that are followed by lower-case letters, as shown below:

Alphanumeric0123456789abcdef…z
Code-point0123456789101112131415…35

(e)At the time of registration, the Member State should provide the UAS operator with the full registration string that consists, in the following order, of:

(1)the UAS operator registration number as defined in point (a); and

(2)the three (3) randomly generated ‘secret digits’, separated by a hyphen ‘-’ (ASCII code [DEC] 45).
