# How can this ACARS message be decoded?

With regards to the text below, can someone offer either advice or a link to a website/document that would help decode ACARS messages.

I am ok with the following:

• QU - ACARS "to" address
• Q - ACARS "from" address
• FML - data from left hand FMS
• FI - Flight Identifier
• AN - Aircraft Number
• IGW1 - Iridium server identifier
• 130710 - date/time of data package sent
• F57A - package identifier

So that leaves the DT QXT info plus the hex from ADS line.

QU REKASCC
.QXSXMXS 130710
FML
FI AB1234/AN G-INFO
DT QXT IGW1 130710 F57A

• Welcome to aviation.SE. Could you please be more explicit on what you do and do not understand? QXT is one, could you list all the terms that you are missing? This will help in giving you a better answer. – Federico Nov 16 '17 at 12:12
• As @Federico says, a list of what you understand and what you don't, will be helpful in providing a good answer. I've modified your question, so that it is much more understandable, but you can always roll-back to your original question, if you don't like the new one.

• For another flight I've managed to get it to convert to this but it's the text on the DT line and POS line that I need help with. Also is there a list of acronyms such as "QXT" that might be available somewhere?
