International Air Transport Association code

International Air Transport Association code is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand International Air Transport Association code rather than just read about it. In short: IATA codes are abbreviations that the International Air Transport Association (IATA) publishes to facilitate air travel. They are typically 1, 2, 3, or 4 character combinations (referred to as unigrams, digrams, trigrams, or tetragrams, respectively) that uniquely identify locations, equipment, companies, and times to standardize international flight operations.

Key takeaways

International Air Transport Association code belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect International Air Transport Association code to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of International Air Transport Association code from memory before moving on to harder problems.

Reference excerpt

IATA codes are abbreviations that the International Air Transport Association (IATA) publishes to facilitate air travel. They are typically 1, 2, 3, or 4 character combinations (referred to as unigrams, digrams, trigrams, or tetragrams, respectively) that uniquely identify locations, equipment, companies, and times to standardize international flight operations. All codes within each group follow a pattern (same number of characters, and using either all letters or letter/digit combinations) to reduce the potential for error.

Airport codes

IATA airport codes are trigram letter designations for airports, like "ORY" (Paris-Orly Airport), "CPT" (Cape Town International Airport), OTP (Otopeni International Airport) and "BCN" (Barcelona-El Prat).

Airline designators

IATA airline designators are digram letter/digit codes for airline companies, like "M6" (Amerijet), "NH" (All Nippon Airways), and "4A" (Air Kiribati).

Aircraft type designators

IATA aircraft type designators are trigram letter/digit codes used for aircraft models, like "J41" (British Aerospace Jetstream 41) and "744" (Boeing 747-400).

Country codes Digram letter codes are used for countries as specified in ISO 3166-1 alpha-2. One additional code is used:

code XU is used to specify part of Russia east of (but not including) the Ural Mountains.

Currency codes Trigram letter codes are used for currencies as specified in ISO 4217.

IATA time zone codes IATA time zone is a country or a part of a country, where local time is the same. IATA time zone code is constructed of 2–4 characters (letters and digits) as follows:

ISO 3166-1 alpha-2 country code is always used as first and second characters of time zone code. If country is not divided into separate time zones – no more characters added. Just 2 characters used. If country is divided into time zones – 3rd character of time zone code is a digit – number of time zone in country. Note: Russia is divided into 11 time zones, so number of time zone in country is specified by 2 digits – RU01, RU02, ... RU11. If some territories have the same local time, but different rules on daylight saving time – a letter can be added as 4th character to make unique codes for all such territories. Example: Time zone code AU2 is used for Australian states New South Wales and Victoria (local time is UTC + 10 hours, DST begins at end of October). Time zone code AU2A is used for Tasmania (local time is UTC + 10 hours, DST begins at end of September). Time zone code AU2B is used for Queensland (local time is UTC + 10 hours, no DST).

IATA region codes IATA region codes trigram letters codes used to specify large territories, consisting of several countries. Following codes are used:

AFR - Africa CAR - Caribbean Sea countries CEM - Central America EUR - Europe TC1 - IATA American Traffic Conference (includes NOA, CEM, SOA and CAR) TC3 - IATA Asian Traffic Conference (includes JAK, SAS, SEA, SWP) TC2 - IATA European and African Traffic Conference (includes AFR, EUR, MDE) JAK - Japan and Korea MDE - Middle East NOA - North America SCH - Schengen agreement countries SOA - South America SAS - South Asia SEA - South-Eastern Asia SWP - South-West Pacific Speaking on region codes and countries, country code RU is used to specify part of Russia west from (and including of) Ural Mountains and country code XU is used to specify part of Russia east from (and not including of) Ural Mountains. Country RU is in EUR region, country XU is in SEA region. For all other purposes only country code RU is used to specify all the territory of Russia. Country code AQ is used to specify Antarctica. Country AQ is not in any of regions listed here.

Name class codes The trigram is composed of the first letter of first name and the first two letters of the names (ISO 9625)

IATA class codes

IATA class codes are 1-letter codes created to help airlines standardize conditions of travel on passenger tickets and other traffic documents.

IATA tax codes List of ticket and airport tax codes:

AB - Government Tax AC - Value Added Tax AE - Passenger Service Charge (International) AF - Airport Departure Fee (Domestic/International) AG - Ticket Tax AH - Airport Tax AI - Baggage Security Screening Fee AJ - Airport Exit Tax (International) AK - Airport Departure Tax (International) AL - Passenger Service Charge (Domestic/International)

Worked examples

Example 1 — a first encounter with International Air Transport Association code

Start with the simplest possible case. Write down what International Air Transport Association code claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to International Air Transport Association code before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about International Air Transport Association code ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of International Air Transport Association code

In research: International Air Transport Association code appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses International Air Transport Association code in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: International Air Transport Association code is common in secondary-school and first-year university syllabi. It links to neighbouring topics Encodings, International Air Transport Association, so understanding it makes those chapters shorter.
In everyday life: Look for International Air Transport Association code outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
