PULSASLOT188 The SDU on 9M-MRO (the aircraft used for Flight 370) logged onto the Inmarsat network at midnight MYT. 33 At 08:19, the aircraft had been airborne for 7 h 38 min; the typical Kuala Lumpur-Beijing flight is 51â„2 hours and fuel exhaustion was likely. After initial analysis determined that Flight 370's last location was within Australia's Search and Rescue region in the southern Indian Ocean, Australia played a major role in co-ordinating the analysis in conjunction with Malaysia. Since the aircraft did not respond to a ping at 09:15, it can be concluded that at some point between 08:19 and 09:15, the aircraft lost the ability to communicate with the ground station. The log-on message sent from the aircraft at 08:19:29 was not immediately well understood. When passing through the satellite, the signals are amplified and translated in frequency-mixed with the signal from an oscillator in the satellite, leaving the satellite at the combined frequency.|30 for 30
