ICAO Code

The International Civil Aviation Organization (ICAO) defines several important codes for use in international aviation:

  • International Civil Aviation Organization airport codes or location indicators (published in ICAO Document 7910 - Location Indicators): 4-letter codes like LSZH for Zürich or HECA for Cairo
  • Airline codes or ICAO airline designators (published in ICAO Document 8585 - Designators for Aircraft Operating Agencies, Aeronautical Authorities and Services): 3-letter codes like BAW for British Airways or AFR for Air France
  • ICAO aircraft type designators (published in ICAO Document 8643 - Aircraft Type Designators): 4-letter codes like A320 for Airbus 320 or B772 for Boeing 777-200
  • ICAO 24bit aircraft addresses: allocation of 24 bit addresses to states to uniquely identify aircraft worldwide

Famous quotes containing the word code:

    “...I had grown up in a world that was dominated by immature age. Not by vigorous immaturity, but by immaturity that was old and tired and prudent, that loved ritual and rubric, and was utterly wanting in curiosity about the new and the strange. Its era has passed away, and the world it made has crumbled around us. Its finest creation, a code of manners, has been ridiculed and discarded.”
    —Ellen Glasgow (1873–1945)
