Nationality, registration and airworthiness
7 min read
Marks (Annex 7)
Every aircraft carries a nationality mark followed by a registration mark, in letters (and digits) that can be read clearly. On aeroplanes: at least 50 cm high under the wings, at least 30 cm on the fuselage or tail.
Combinations that could be confused with distress or urgency signals (such as SOS, PAN, XXX, TTT) five-letter combinations used in the International Code of Signals, or three-letter combinations beginning with Q used in the Q code, are not used.
The certificate of registration is issued by the state of registry and carried on board. An aircraft is registered in one state only.
