In the IATA Airport Handling Manual procedures, messages are send to communicate with the transit station to describe the cargo load. The Load message LDM (AHM 583) is sent primarily to enable the transit station to know in advance the load which continues on the same aircraft.

LDM ZZ999/13.ZZOEA.Y136.2/4
-CMB.27/22/12/3.T3500.1/2800.5/700.PAX/61.PAD/0 SI

In here we got hold id 3 total gross weight 1000kg,... In our automated system, we need info in compartment bay level.

How can we get those information?

  • Any other message like Container / Pallet Distribution Message CPM (AHM 587)?
  • Or we have to manage manually (should distribute by load controller)

  • $\begingroup$ thanks @mins yep It is related with IATA telex.. I parsed those LDM message. but those details are in abstract level (e.g total gross weight 1000kg in hold id 3 --> refer 3/1000). how can we get some specific details like what is the weight distribute in compartment bay (32L). note several compartment make a hold level. can any one who handling AHM messaging / Sita telex plz help me $\endgroup$

    $\begingroup$ I'll edit your post to make it more readable for this community. If you want to roll back to your version and improve it on your own, just use the edit link. You should still explain the context: Are you a developer or a user? Are you using an application or an API? Which one? $\endgroup$

Paranee, There is no such detail in the LDM, it is just a WEIGHT value. There maybe specifics for certain SL/DG (review AHM again for those) as some SL/DG are required to show location and some location and weight - explained in AHM.

BUT - LDM is just an overview, not very specific as it does not need to be. For a through flight A>B>C, where A is OFFLINE to your system, if you have received teletype LDM for processing and you are doing the sector B>C then any load B>C is just shown (know by the system) as TRA (transit) load - nothing more. No more detail.

However for unitized aircraft, the CPM complements the LDM to show the detail required by bay as opposed to HOLD and/or COMPARTMENT.
