Quoting washingtonflyer (Reply 21): 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.
