Reading comprehension
The objective of this activity is to get specific information from a text about airport codes written in standard language and also to write the answers by using the appropriate structure.
Read the following text and then answer the comprehension questions below with complete sentences.
Airport codes
All airports have an airport location identifier, commonly known as airport code, which is often, but not always, the abbreviated form of the common name of the airport.
The origin of airport and location codes –which can be quite confusing– can be traced to the National Weather Service (NWS) in the early years of the 20th century. The NWS used to tabulate data for cities and gave each one a two-letter identifier. So, when air travel exploded, existing airports put an X at the end of their identifier, hence LAX for Los Angeles International Airport. A government official then drafted the three-letter system we have in place today, which effectively produces 17,576 different combinations. This has further evolved to include four-digit identifiers with numbers in the code.
The International Air Transport Association (IATA), the International Civil Aviation Authority (ICAA), the Federal Aviation Administration (FAA) and the International Organization for Standardization (IOS) are collectively responsible for assigning these codes, of which there are a few main types:
- Airline Codes (e.g., DL is the IATA’s code for Delta).
- Airport Codes (e.g., ORD is the IATA code for Chicago O’Hare).
- Aircraft Codes (e.g., 320 is the IATA code for the Airbus A320).
- Country Codes (e.g., US is the IOS country code for the United States).
- Location Codes (e.g., GVA is the IATA code for Geneva; locations can also include bus stations, ferry ports, heliports and metropolitan areas, to name a few).
Airports are uniquely represented by their IATA airport code and ICAO airport code.
The assignment of a three-letter alphabetic code is governed by the International Air Transport Association (IATA) Resolution 767, and it is administered by IATA headquarters in Montreal. The codes are published biannually in the IATA Airline Coding Directory.
Many codes are simply the first three letters of the city name. The codes are not quite unique: 323 of the 17,576 possible codes are used by more than one airport.
IATA codes are an integral part of the travel industry, and are essential for the identification of an airline or a logistics company, its destinations and its traffic documents. They are also fundamental to the smooth running of hundreds of electronic applications which have been built around these coding systems for passenger and cargo traffic purposes.
While the IATA codes are the most familiar airport codes, the 4-letter International Civil Aviation Organization (ICAO) airport codes are also common. The ICAO airport code is a four-letter alphanumeric code designating each airport in the world.
These codes are defined by the International Civil Aviation Organization and are used by air traffic control and airline operations such as flight planning. They are not the same as the IATA codes which are used for airline timetables, reservations, and luggage handling. ICAO codes are also used to identify weather stations, whether or not they are located at airports.
Unlike the IATA codes, the ICAO codes have a regional structure. In general, the first letter is allocated by continent and represents a country or group of the ICAO flag countries within that continent. The second letter generally represents a country within that region, and the remaining two are used to identify each airport. The exceptions to this rule are larger countries that have single-letter country codes, where the remaining three letters identify the airport.
In the United States and Canada, most airports which have been assigned three-letter IATA codes use the same code with leading “K” or “C” as their ICAO code; e.g., YYC (Calgary International Airport, Calgary, Alberta) and CYYC, IAD (Dulles International Airport, Chantilly, Virginia) and KIAD.
