ACARS and Dispatchers/Flight ops

[G-BPEC]

Hi,

I have a question for any dispatchers/flight ops people who have experience of working with ACARS. my question is what happens to the message once it is recieved by you? How is it recived and what does it look like, and more to the point how do you decipher the necessary information from that jumbled up mess of letters and digits that most ACARS messages seem to take? Any help on this would be greatly appreciated.

Also, can anyone help me with a long standing query, and BA people perhaps? On a BA ACARS message, usually from 75/3/6 7's, you tend to get something that looks like this:-

DAVCS KIJUE
Are these the pilots names or something?
Thanks a lot in advance
