It's a little difficult to understand why the ACARS message transmit times have been discounted. If the pitot disagreement preceded the Cavalry Charge (AUTO FLT AP OFF received at 02:10), why was the PROBE PITOT message buffered in the computer (and not sent) for one minute thirty-nine seconds?
The sequence of ACARS messages is easy to misunderstand if you don't know how the hierarchy works. Fault codes are batched and transmitted in hierarchical order every minute, but warning codes are sequenced in real time - though also time-stamped to the nearest minute. Even though the fault codes are batched with a minute time-stamp, their transmission sequence is still subject to other warning messages taking precedence.
It makes sense if you consider that the pilots get all the warnings in real time, whereas for maintenance purposes the source of the warning(s) is recorded as a fault.
The following interactive
ACARS list has the minute attributed to each message highlighted in a different color. Each line will change color as the cursor passes over it, and if clicked will be highlighted in yellow. Click each highlighted line again to restore it to normal.
