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:

    “Many people will say to working mothers, in effect, “I don’t think you can have it all.” The phrase for “have it all” is code for “have your cake and eat it too.” What these people really mean is that achievement in the workplace has always come at a price—usually a significant personal price; conversely, women who stayed home with their children were seen as having sacrificed a great deal of their own ambition for their families.”
    —Anne C. Weisberg (20th century)
