At precisely 1:02 flight APA 791 comes into the ARRIVING section. At 1:09 it transmits its arrival message. I found that particular message in the sources and it's the pic.

If you look at the middle part of this picture:

you can see that this certainly seems to be the data which would fill these formatting strings. It's clock times when a plane with a certain flight name arrive and when they should depart from gate, as well as a bunch of other magical numbers I have yet to figure out. Some of the numbers most certainly tell the game which entry point in the air they are using to come in. Others should denote airplane model (different sprites).

To me this all seems like a straight forward case of fucking around and finding out, until something cool happens.
