Hi doc!
I kinda think they got this confused. When I started checking out her daily routine, it was busy. For like the three or four days before , she ran on schedule, for the most part. Which is tough to do, where there are a lot of short hops.
If she had to turn around that many times she would end up starting to run late. And there was not a like stop 2 late stop 3 later on any days right before she crashed.
BUT, on one site they had the route being flown by a Boeing aircraft consistnetly, and then there was a change to the AIrbus like 4 days earlier.
So I am wondering if the Boeing ( it would be the same flight number) was the aircraft that was having trouble and the AIrbus took over. That is just specualtion.
But ACARS transmits on every single aircraft all the time. It is not an emergency thing. It has several functions, but it will tell on every flight and report it when the aircraft pushed from gate, exact time airborne, exact time pulls into the gate down the line. That is typical how it is designed.
It also is (again it is not an emergency deal) tranmitting to the ground if there is a abnormal system problem, it will tell the ground at the next part of any leg, I am sensing a overheated whatever. That is so the maintence guys at the next aiport can start diagnsing, get part replacement etc before landing in an effort to keep on time.
There are tons of ACAR messages - light out in toilet 4a , I dont know seat light in row 4n not working - your with me! ACARS in most instances are more "maintenancy" stuff. Obviouly the transmissions from this one were far more serious, but the story "reads" as if ACARS tranmitting inidcates some major deal, when that is not what it is for in the first place.
I kinda think the route was changed to the AIrbus, casue the Boeing kept having some glitches, that after the third time they concluded we need to pull her, so we can get to the bottom of this as to why it keeps happening.
There is no way a flgiht can be running on time if the way this "reads" throughout the 24 hours- espcecially since she had so many segments, that kinda deal would have a huge cascading effect all the place.
Now maybe the sites were both off, but they did not match that is for sure!!
just speculating here, But I agree with you the translation is bizairre or they think ACARS is always some big ordeal
Starting around page 10 here, you can see some of them, mostly pretty mundane stuff
