| @dublin4711- in aviation, there are two ways to identify airports, by the ICAO code or by the IATA code. ICAO codes are four alpha-numeric codes to identify ever airport in the world, including small airports, and each country's airports are identified with specific letters. for example, most airports in the united states begin with K_ _ _, or in northern europe with E _ _ _ (with the second letter specific for different countries), in japan RJ_ _, etc. Large airports that are served by commercial, cargo, or charter flights are also identified with a three-letter IATA code, which in many instances just drop the prefix from the ICAO code (which is why canada's airports all start with Y, because the ICAO code patterin is CY_ _). In the US and canada (with the exception of alaska and hawaii), the IATA code is just the ICAO code with the first letter dropped, but most airports around the world have an IATA code that is just used to identify the airport or city (for example, LHR instead of EGLL, HKG instead of VHHH, ATH instead of LGAV, etc. |
