IATA Telex Types Definition

Updates about the online telex processor here

Working in the airport IT industry you are always challenged with integration tasks at each airport. Usually you face a heterogeneous landscape of home-brew or taylored solutions and standard software running on anything from mainframe to virtual instances in a private clouds. Using an ESB we can tackle a lot of interfacing work and focus on the data integration part. One interface that you will find on all airports that operate commercial flights, is a link to the SITA network to send and receive IATA Telexes.

It is hard to find any information online, so I summarised the available message types here. Btw, these telex types are often referred to as SITA Telex types, which is not correct, IATA (Air Transport Association) defines the available telex types and SITA is operating the network to distribute the messages between airlines, airports, ATC, groundhandling agents and other relevant members of the airport community.

This list should be almost complete, giving you the type, the description and the AHM (Airport Handling Manual) or RP (Recommended Practice) reference. The AHM that you can purchase from IATA gives you all the syntax and details for most of the available types.

Disclaimer: The list might not be correct or complete. It is for educational purpose only. For reliable information please refer to the IATA manuals.

MVT, LDM, PTM, TPM, CPM, PSM, UCM are among the most common telexes from my experience. If you implement a telex interpreter you definitely need to implement these types first.

I am working on an online telex processor, a demo version I will put online soon.

  1. Hi Sven, thank you for a comprehensive list. I am looking forward to seeing your online processor.

    Kind regards,
    Thomas

  2. Hi Sven.

    I’ve found your page when I looked for sita telex, so you’re developing an online telex processor! I’am (and we are) very interested about it, becouse we are going to develop one as well. Maybe we can cooperate late. I’m waiting for your first demo and than we can talk about the future if you are interested about it as well!

    Thanks

    Good Luck: Zoltan Nagy

  3. Hi Sven
    Thanks for the list. Do you know any link to the RP descriptions

    IATA RP 1707b,1708, 1709, 1715, 1717, 1718.. ?

    Best regards Hans

    • I gave up on searching for it online. I look into printed versions from customers. Or you buy it from IATA…

  4. Thanks full for the information, Now can you help me something about this. ?

    Can you help me to write the order in a form of Telex message about…

    The order..

    please send the telex to the relevant agencies to prepare a wheelchair (WCHR) for a passenger before on board.

    Detail..

    1. Name of passenger : MR.Smith Johnson, 70 years old (Elderly Passenger)

    2. Flight : CX700/CX356/11FFB/BKKHKGLAX

    3. Departure : BANGKOK (BKK)

    4.Transit : HONGKONG (HKG)

    5. Arrival : LOS ANGELES (LAX)

    6.TELEX sent from Ground Staff : KP

    How to write these all in form of TELEX ?

    This is my homework but i don’t understand about this lesson because i couldn’t go to a class for awhile cause an accident by a motorbike.

    Please help me if possible.

    I’m a girl from Thailand. I’m studying about Airlines Business Management. I want to be a ground staff or maybe a cabin crew if it possible. 🙂

    Thanks for your help 🙂

    • You need to create a PAL message (Passenger Assistance List) according to IATA PSCRM RP1707b.

      Should be similar to this, not to sure about transit:
      QK HKGTGKP LAXTGKP
      .BKKTGKP 110230
      PAL
      CX700/11FEB BKK PART1
      1SMITH/JOHNSON
      .R/WCHR HK1
      ENDPAL

      • Thank you so much 😀
        I though that maybe i send a paper with out an ink to a teacher cause i can not do it and lose my points (just 2 points but it’s important for me so much)

        Thank you a lot Devdude 😀

    • There’s no real rule for e-mail addresses. For industry Type B teletype messaging, the address is constructed by 3 parts:
      – 3 chars for PCC (pseudo city code, an airport like LGW for Gatwick or a city such as LON for London)
      – 2 chars for PR (printer routing, nowadays I would say “functional area” such as RM for machine readable reservations messaging)
      – 2 chars for carrier code (e.g. BA for British airways)

  5. 1/ What about the following:
    – COM
    – ETL
    – PRL

    2/ Does any one know how to write / create a standard PNL telex out of a normal PAX list?? What are the rules and criteria? Is there a manual which I have to read first?

  6. Dear All
    any one can explain LDM
    example

  9. Please, i have a doubts
    1. LDM is a standard format?
    2. Airlines must always use this format or free?
    3. what is the meaning PAD? and what are the parameters?
    4.- for example: PAX/0/163.PAD/0/1for
    Thank you!

    • PAD Is Passenger available for disembarkation. Refers to staff pax on board.
      PAX/0/163.PAD/0/1 is NIL passenger in first class/163 passengers in economy. NIL staff passengers in first class and 01 staff passenger in economy.

    • Hi Sam,

      RFL is a dangerous goods classification, just means they have a RFL loaded, FFM will have the information on which unit it is load in and CPM the position of that unit

  10. Dear All,

    Can anyone advise on below PSM message, why many routing address(BEGOXJU BEGKWJU BEGPHXH AUHPXXH) are present in one message?

    QU BEGKKJU BEGOXJU BEGKWJU BEGPHXH AUHPXXH AUHLCXH
    .HDQKMJU 070813
    PSM
    JU0800/06APR BEG PART1
    -AUH
    1POPOVIC/SLAVKOMR 3A
    APFT
    ENDPSM

    Thanks,
    Vicky
