National Character of Aircraft


The nationality of an aircraft is determined by the state in which the aircraft is registered. This principle was recognized by state practice soon after air flight proved feasible and was incorporated into the Convention on International Civil Aviation of December 7, 1944 (Chicago Convention). Applying the same concept of nationality to aircraft as is applied to maritime vessels provides a basis for a state to maintain jurisdiction over an aircraft while it is flying through international airspace and establishes the power of the state to regulate what happens on board the aircraft regardless of its location. Under the Chicago Convention, contracting states register aircraft according to their domestic laws. When it registers an aircraft, the state must also certify that the craft is airworthy and has appropriate markings identifying the nationality and registration of the aircraft.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
