Data is collected and downlinked via teh airplane communication addressing and reporting system. <br /><br />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.<br /><br />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.<br /><br />I think someone got excited about some data after airFrance crash and made it as if all this data was available somewhere.Kodhambohttps://www.blogger.com/profile/06223497162089820128noreply@blogger.comtag:blogger.com,1999:blog-4320628892565328183.post-78809305629860206412014-03-13T07:13:00.014-07:002014-03-13T07:13:00.014-07:00All of this is incorrect; there is no engine data ...All of this is incorrect; there is no engine data that was transmitted to engine manufacturers.
