052

052 is a numeric designation that appears in several unrelated contexts, ranging from transportation and communications to military and scientific nomenclature. In the field of aviation, 052 is the ICAO airline designator for an airline that operates regional charter services, primarily within its home country. The code is used in flight plans and air traffic control communications to identify the carrier.

In telecommunications, 052 serves as an area code in certain countries, designating a specific geographic region for landline telephone numbers. The prefix is assigned by national regulatory authorities and is required when dialing to or from locations within the code’s coverage area.

Within the military sphere, 052 historically identified a unit or equipment model. For example, in some armed forces, the “052” designation has been applied to a particular class of patrol boats, signifying specifications such as hull length, displacement, and armament, as documented in defense procurement records.

Astronomy and space science occasionally use three‑digit numbers for cataloguing objects or missions; a "052" identifier may appear in lists of minor planets, where it denotes the sequential discovery number assigned by the Minor Planet Center.

In the Gregorian calendar, the number 52 is sometimes informally referenced as “day 52,” corresponding to February 21 in common years and February 20 in leap years, marking the point at which the year is roughly one‑fourth complete.

Overall, the meaning of “052” is highly dependent on the specific domain in which it is employed, with each usage providing a concise label for identification, routing, or classification purposes.
