Below are examples of the use of call signs and their abbreviations.

4.6.3 Aircraft call signs

Callsigns are letters that indicate an aircraft's unique identification, which are

used to ensure clear and unambiguous communication between the aircraft

and the ground unit.

The first or first two letters of the callsign tell where the aircraft is registered.

For example, OY is the designation for aircraft under Danish registration.
