Like radiolocation, it is a type of radiodetermination.

In accordance with the Convention on International Civil Aviation (also known as the Chicago Convention), all civil aircraft must be registered with a national aviation authority (NAA) using procedures set by each country.

Every country, even those not party to the Chicago Convention, has a NAA whose functions include the registration of civil aircraft.

An aircraft can only be registered once, in the one jurisdiction.

The NAA allocates a unique alphanumeric string to identify the aircraft, which also indicates the nationality (i.e., country of registration) of the aircraft, and provides a legal document called a Certificate of Registration, one of the documents which must be carried when the aircraft is in operation.

According to the International Civil Aviation Organization (ICAO), a runway is a "defined rectangular area on a land aerodrome prepared for the landing and takeoff of aircraft".

Runways may be a man-made surface (often asphalt, concrete, or a mixture of both) or a natural surface (grass, dirt, gravel, ice, or salt).

An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller.

Airplanes come in a variety of sizes, shapes, and wing configurations.

The broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research.

Commercial aviation is a massive industry involving the flying of tens of thousands of passengers daily on airliners.

Most airplanes are flown by a pilot on board the aircraft, but some are designed to be remotely or computer-controlled.

Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft.

The word aviation was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb avier (synonymous flying), itself derived from the Latin word avis ("bird") and the suffix -ation.
