That map is way too conservative. It shows the range as not even making it to its intended destination - PEK.
The range is not based on fuel but on estimated flight time.
|Quoting hamiltondaniel (Reply 30):|
It's not really possible that kind of information is showing up on some aviation consultant's Twitter, is it? Surely something that astounding would be leaked not to him but to a reputable newspaper.
I believe he is speculating, like most folks.
Not necessarily. ACARS is a means of transmitting data, in this case EHM data sent from a module in the Trent engines.
|Quoting jetblueguy22 (Reply 50):|
If they have a Boeing maintenance package Boeing would get it. In this case it seems they have a Rolls Royce package, so they get the data.
All of the modern RR
engines have the ability to send EHM data.
|Quoting spacecadet (Reply 51):|
Is it possible that the engine manufacturer gets *all* the data, and only gives the *airline* what it subscribes to? Meaning RR would have everything, but in a normal flight just not give it to MAS because they didn't pay for it?
No. In fact the airline pays $5-6 for each message sent. Malaysia has 60 aircraft in its fleet, those costs add up. They will only send what they want to send.
|Quoting LTC8K6 (Reply 2):|
Presumably, they received a summary? And thus know when the flight ended?
For the reasons as above, I would think MAS would use gatelink for the summaries, which uses a WLAN connection on the ground, rather than transmit via ACARS.
|Quoting Starlionblue (Reply 58):|
I get the feeling that RR analyzes the data and then reports useful parameters and trends to MH. I don't know if MH would need the raw data. Note that this is of course just conjecture on my part.
The raw data is the intellectual property of the airline, not the OEM.
|Quoting hamiltondaniel (Reply 60):|
He has made several tweets about the purpose of whatever happened to the flight being "asset acquisition" of 20 employees of Freescale Semiconductor who were on the plane
Seems odd to me that a caper involving 20 engineers didn't result in proper disabling of the a/c broadcasts.
