+
+## Acronyms / Codes
+
+...
+
+## Analysis
+
+The format seems to be comma-separated values with a '/' as a line separator.
+
+Taking the three examples above, the first line listed in order:
+
+```
+A320,007078,1,1,TB000000
+A320,015737,1,2,TB000000
+A320,002986,1,1,TB000000
+```
+
+The second field looks like a message number.  The third field is always 1, but the fourth field is 2.  fifth field is always TB000000.
+
+```
+REP019,64,01,1
+REP026,84,01,1
+REP003,64,01,1
+```
+
+The REP line has a different starting number for each of these examples, but there's not enough data to conclude anything.
+
+```
+CCD-AINZ,AUG31,130953,EDDF,EGLL,0007
+CEC-NCS,AUG31,151713,LEVC,EGKK,8944
+CCJY-RAA,AUG31,153516,EGCC,OJAI,0116
+```
+
+The line starting with a 'C' is either CC or CE, but includes the tail number, date and time, origin and destination IACO codes.  No idea what the last digits are.
+
+```
+C0SW060063130001
+C0TWP02VLG030101
+C0SW019040420021
+```
+
+There's not much to go on here, but the Vueling (VY) aircraft appears to have a very different set of characters here - VLG meaning Vueling?  Is this a version or serial number?
+
+
+```
+C106,82020,5200,50,0011,0,1100,50,X
+C101,67920,4000,30,0000,1,0000,30,1
+C151,22610,4000,50,0010,0,0100,50,X
+```
+
+Unsure what these are.
+
+```
+CE0010,16989,270,556,6384,334,W22013
+CE0308,00056,---,---,----,---,W22G03
+CE0010,20680,298,656,6656,265,W22042
+```
+
+Again, unsure what these are.
+
+At this point, the data appears to differ.
+
+```
+EC771860,11071,07209,C3,15,055
+```
+
+The LH reports this, whilst the VY reports:
+
+```
+C21020420-4-121  
+C35010269        
+C45321231-23     
+C55321160-07     
+C61020420-2-121  
+C74665934        
+C85321231-23     
+C95321160-07     
+```
+
+And the RJ reports:
+
+```
+C21020420-3-121
+C33PXAU00308
+C45321231-23
+C55321160-07
+C61020420-3-121
+C73PXAU00401
+C85321231-23
+C95321160-0
+```
+
+Are these something to do with the cargo hold?  ISO 6346 covers intermodal shipping containers, maybe there is a similar for aviation?
+
+The LH doesn't report anything as it's a cargo flight.
+
+```
+EE771232,12921,08769,C3
+```
+
+Unknown.
+
+From here, the messages start with E, N, S, T, V and X.  They are grouped by the second digit, i.e. the x1xxxx messages form a group, as do the x2xxxx messages.  The groups do not contain all members, but always contain and 'S' and a 'T'.  'E' and 'N' are either both present, or both absent:
+
+* E/N/S/T/_/X
+* E/N/S/T/V/X
+* _/_/S/T/_/X
+* _/_/S/T/V/X
+
+Numbers start at 1 and increment, with gaps.
