The origins of the N in the U.S. Registration can be traced back to the Commission Internationale de Navigation Aerienne (CINA – the Convention for the Regulation of Air Navigation) established as part of the Paris Peace Conference immediately following World War I. A part of this conference was the adoption of the Convention for the Regulation of Air Navigation that laid the foundation of the system of international aircraft identification still in use today. In these proceedings, the first letter(s) of the identification designating national origin are set. Each major participating country was allowed a single identifying letter and to specify their own designation letter. The U.S. Delegation was allocated “N.”

The reason the U.S. Was allocated “N” for its national registration mark comes from existing regulations of wireless communications in place in 1919. The International Telecommunications Union (ITU, formed in the late 1800s to provide international standards in telecommunications and still going strong today) held its first International Wireless Telegraph Conference in Berlin in 1906. Here the first Service Regulations were established for governing international radiotelegraphic communications. It was at this conference that S-O-S was adopted as the international radio distress call. By 1912, the proliferation of wireless radio stations, both land and ship based, had created chaos in the airways as each base (or country) was creating their own call-signs for identification leading to the potential for call-sign duplication. In 1912 at the London International Radiotelegraphic Conference, the Service Regulations were expanded to include a protocol for international radio call-signs. In short, the following identifiers where assigned to major countries:

G – Great Britain
D – Germany
F – France
I – Italy
J – Japan
N, KDA-KZZ, Wxx – United States

The reason “N” was assigned to the U.S. Was in recognition of the industry leading development and deployment of wireless communications by the U.S. Navy that had been using “N” as the prefix to its station call-sign identifiers since 1909.

The answer is in Part 47.31 sub c.(1) http://www.gpo.gov:80/fdsys/pkg/CFR-2012-title14-vol1/xml/CFR-2012-title14-vol1-sec47-31.xml
Temporary registrations are good for 90 days. The FAA may extend that by letter if there is a reason.
The temporary form must be carried in the aircraft just as would the actual registration.

All of them.

admin answers:

SAS has airplanes registered equally in Denmark, Norway and Sweden -
OY-registry, LN-registry and SE-registry -
By agreement, the jurisdiction is shared by the 3 countries -
SAS “operating address” is at the CPH Kastrup airport -
The proportion of stock was 40-30-30% among the 3 countries -
I cannot recall which one has the 40% stake – could be Sweden or Denmark…? -

Be aware that there are airplanes leased from companies in other countries -
But then the jurisdiction is in fact (by exception) for the operator (airline) -
Not the country of registry -
Example, Singapore Airlines has many airplanes under USA “N-registry” -
These are leased in USA, but the law applicable inside the airplane is Singapore -
Singapore being the operator -

Pilots have a special purpose FAA license issued for operating N-registries -
See FAR 61.77 which applies for that case -

I have operated airplanes of various registries (countries) -
USA, France, Indonesia, Iceland, Germany, Argentina, the Netherlands, Belgium -
I did not have a licence issued by these countries – just a letter of authorization -
What “counts” is the country of the operator (airline), not registry -
That is in the case of leased airplanes -
