your 2nd point not valid MAS did not use satcom for any data transfer (no contract) used vhf (and perhaps HF)
Thank you, although are you really sure Malaysia Airlines not using SATCOM?
press release dated 21/07/2010
Malaysia Airlines has chosen Thales’ TopFlight satcom (TFS) for its new B737s. This new ARINC 781 standard of satcom continues to support Inmarsat aero services for flight deck voice and data connectivity. In addition, for airlines that have the Thales IFE system, the TopFlight satcom enables data throughput to the passenger seat for internet connection......
and another older press release about inflight mobile phone usage.
"We are also very well placed to upgrade our capability with Malaysia Airlines as, uniquely, the Honeywell avionics are already in place on their fleet to enable future Inmarsat SwiftBroadband upgrades later this year".
The first Malaysia Airlines B777-200 was installed with the AeroMobile system during a routine maintenance check.
Very nice article covering MH370 and SATCOM in detail.
