On Monday night (Mar 24), Malaysia Airlines concluded that all 239 people on board Flight MH370 had perished based on evidence given to it by the Government, MAS chairman Tan Sri Md Nor Md Yusof explains how they came to it.
According to The Star, acting Transport Minister Datuk Seri Hishammuddin Hussein shared that they came to the conclusion that the flight ended in the southern Indian Ocean using data that was analysed by Inmarsat and UK's Air Accidents Investigation Branch (AAIB).
Here are a few paragraphs from his press briefing yesterday, Mar 25:
"While on the ground at Kuala Lumpur airport, and during the early stage of the flight, MH370 transmitted several messages. At this stage the location of the aircraft and the satellite were known, so it was possible to calculate system characteristics for the aircraft, satellite, and ground station.
"During the flight the ground station logged the transmitted and received pulse frequencies at each handshake. Knowing the system characteristics and position of the satellite it was possible, considering aircraft performance, to determine where on each arc the calculated burst frequency offset fit best.
"The analysis showed poor correlation with the Northern corridor, but good correlation with the Southern corridor, and depending on the ground speed of the aircraft it was then possible to estimate positions at 0011 UTC, at which the last complete handshake took place. I must emphasise that this is not the final position of the aircraft.
"There is evidence of a partial handshake between the aircraft and ground station at 0019 UTC. At this time this transmission is not understood and is subject to further ongoing work.
"No response was received from the aircraft at 0115 UTC, when the ground earth station sent the next log on / log off message. This indicates that the aircraft was no longer logged on to the network.
"Therefore, sometime between 0011 UTC and 0115 UTC the aircraft was no longer able to communicate with the ground station. This is consistent with the maximum endurance of the aircraft."
Hisham said:
"The new analysis I have described above was convincing enough for the AAIB to brief the prime minister that MH370 flew along the southern corridor, and that its last position was in the middle of the Indian Ocean, west of Perth.
"Within a few hours, the families had been informed, and the prime minister announced the new development to the world."
MAS chairman Tan Sri Md Nor Md Yusof also added to that:
"That position is very far away, very remote ... and after 17 days, we could only bring ourselvesto this certain conclusion,” he told reporters at the KL International Airport here yesterday."
He also denied that the airline had delayed evidence from being released publicly.
