Quoting chrisrad (Reply 2): THE search for missing Flight MH370 has been thrown into yet more confusion after a key Malaysian military chief denied earlier reports that radar had spotted the plane hundreds of kilometres off course.
Air force chief General Rodzali Daud was quoted in a local pro-government newspaper as saying a military base had detected the Malaysia Airlines aircraft near an island in the Malacca Strait, far to the southwest of where it should have been headed. |
This is becoming a mess. An official says A, media says "A said B".
What's worse is that, media goes to C, and ask about A, and C would say, "Yea yea... A said B"...
You can see how far and fast that can go off track.

Question: Where is it now then? We're talking about a 777-200ER not a B-2 stealth bomber!
Quoting Web500sjc (Reply 6): Sorry just came to my mind, what happens to a fly by wire airplane , like the B777, B787, A320-A380 if there is a total electrical failure? how controllable would it be? |
Total electrical generation failure = RAT (Ram Air Turbine) would deploy and power the necessary electrics.
The aircraft is still controllable as the FBW is then powered by the RAT through the necessary electrical buses.
Quoting Starlionblue (Reply 20): In the case of 777, 320, 330-340 you end up in what is called manual reversion. |
Manual reversion is only there in terms of total systems failure ie: the
HYD AND ELEC systems are unpowered. The 737 has manual reversion... 777, 320, 330, 340, 767, 747 do not.
Quoting Mark2fly1034 (Reply 12): How is it if I lose my $500 iPhone I can find it right away anywhere in the world but a $250 million dollar aircraft goes under the radar. There has to be stuff not being told to the public. |
If you lose your $250 million dollar aircraft its easy to find it as long as you know it's at an airport anywhere in the world.
This case isn't the same as "if I lose my iPhone I can fnd it anywhere in the world"... try and lose it in an area with no cell coverage... or simpler enough, get on a speedboat, blindfold yourself, and throw the phone overboard... let's see how easy it is to find it... Not so, right?
Even better... get on a speedboat, blindfold yourself, switch the phone off... then wait a few moments, then throw the phone overboard... U still wanna say you can find it anywhere in the world?
Muslim pilots will say Allahu Akbar when they are scared, in distress... etc...
It was said in the KI574 fatal dive by both pilots... in fact, they screamed it in a fearful tone on the last moments... Not suicidal or terror is it?
Quoting airplanedaj (Reply 26): Does anyone know for sure whether or not it applied to 9M-MRO? I only ask because there are two placements for SATCOM antennas, as discussed in earlier threads |
9M-
MRO does not have the High Gain Antenna.
It may have the Low Gain Antenna... but I can't confirm it due to its size, but there is a 3rd 'blade' (the front most) between the wing's trailing edge and the tailfin along the top of the fuselage.
Quoting dirktraveller (Reply 36): Thanks for the information, I wasn't aware of Kota Bharu being the closest airfield, that should be capable of handling their B777 right? |
In am emergency, yes.
Kota Bharu is 2400m x 45m with strong pavements... albeit narrow, but can be used for emergency.
The other thing, they could have simply made a 180 turn and go to the better choice, Kuala Trengganu, which is designated as an alternate/emergency field for widebody ops in
MH. 3480m x 45m.
And bear in mind between those two, there's also Gong Kedak Airbase too. (and yes, the proximity of this airbase along with primary radar facilities nearby, make me dismiss the "they went to strait of Malacca" theory).

I'll think about it if you call me Mandala instead of Mandela...
Quoting Enobar (Reply 34): What information is relayed? The AF447 flight obviously had the more advanced subscription and relayed a whole heap of information before crashing - does it supply GPS coordinates? If so I wonder why it took so long to locate the wreckage. If not - it would perhaps not have made as big a difference to the SAR effort of MH370 as some seem to think..
And... It begs the question as to why ACARS would not relay GPS coordinates.. Surely if is already sending so much data back to HQ, would a set of coordinates really be much more data to send? |
ACARS messages are not very long, and depending on the package you subscribe to to ARINC or SITA, this can be expensive. This is why carriers are beginning to look into (and some have moved altogether) outside ACARS...
Again, it's a matter of cost.
