Where is that plane? It can be in Australia, Korea, Pakistan, anywhere? God this is scary.
US
investigators suspect the missing Malaysian airliner was in the air for
four hours after its last confirmed contact, and may have been diverted
to an unknown location, the Wall Street Journal reported on Thursday.
It said US aviation investigators and national security officials are basing their theory on data automatically downloaded and sent to the ground from the Boeing 777's Rolls-Royce engines, which suggested the plane flew for a total of five hours.
The WSJ attributed the information to two unidentified sources "familiar with the details". Contacted by AFP, Rolls-Royce in Singapore said it could not comment on an ongoing investigation.

All of this is incorrect; there is no engine data that was transmitted to engine manufacturers. Wall street journal is talking out of its ass.
ReplyDeleteTo add to the earlier comment, I will talk more about the Boeing Airplane Health Management (AHM) system here.
ReplyDeleteAHM collects data from ACMS or CMC; In addition, it collects data from the electronic flight bag. Data is collected and downlinked via teh airplane communication addressing and reporting system.
It provides ground repair crew with data about possible fault states in the aircraft; it gives times of flight vs torque and other engine data. However, I am not clwear waht data regarding catastrophic failure is transmitted.
MAS is not a subscriber to this service. This service is mainly used by US/Western European airline companies because they have good inflight wifi systems that can transmit digital data. In places like India, and Russia, this data would be simply cached when wifi is not available, and transmitted when the wifi systems become available. For this reason, Trans-Asian flights and trans pacific flights do not have this system installed.
I think someone got excited about some data after airFrance crash and made it as if all this data was available somewhere.
