What's the MSA over the part of the Malaysian peninsula that they might have flown to get to the Malacca Straits?
The minimum off route altitude is at its highest around Ipoh (WMKI). It is 9500ft there.

Anyone remember the three Ugly Sisters at QF, one developed a massive crack in the fuse which could have easily sent it to the bottom of the Pacific.

I hope not but could the ex MAS B744 crack, caused by illegitimate sealant removal using a box cutter, be repeated again? :uhoh:

Often it pays to look at history, as it has a habit of repeating itself.

A semi-retraction from the RMAF.

IMHO this is ridiculous butt-covering. Any credible SAR effort would not commit such serious assets to a search area so diametrically opposed to the track of the aircraft in question without very good reasons.

The Malaysian political imperatives now seem to be taking over, leading to an impression of a confused SAR effort.

The Malaysians need to be upfront here. Already the suspicions of a cover up are beginning.


OFFICIAL STATEMENT BY CHIEF OF ROYAL MALAYSIAN AIR FORCE ON
BERITA HARIAN NEWS ARTICLE DATED 11th MARCH 2014 ON SEARCH AND RESCUE OPERATIONS IN THE STRAITS OF MALACCA

1. I refer to the Berita Harian news article dated 11th March 2014 on Search and Rescue Operations in the Straits of Malacca which (in Bahasa Malaysia) referred to me as making the following statements:

The RMAF Chief confirmed that RMAF Butterworth airbase detected the location signal of the airliner as indicating that it turned back from its original heading to the direction of Kota Bahru, Kelantan, and was believed to have pass through the airspace of the East Coast of and Northern Peninsular Malaysia.

The last time the plane was detected by the air control tower was in the vicinity of Pulau Perak in the Straits of Malacca at 2.40 in the morning before the signal disappeared without any trace, he said.

2. I wish to state that I did not make any such statements as above, what occurred was that the Berita Harian journalist asked me if such an incident occurred as detailed in their story, however I did not give any answer to the question, instead what I said to the journalist was “Please refer to the statement which I have already made on 9 March 2014, during the press conference with the Chief of Defence Force at the Sama-Sama Hotel, Kuala Lumpur International Airport”.

3. What I stated during that press conference was,

The RMAF has not ruled out the possibility of an air turn back on a reciprocal heading before the aircraft vanished from the radar and this resulted in the Search and Rescue Operations being widen to the vicinity of the waters of Pulau Pinang.

4. I request this misreporting be amended and corrected to prevent further misinterpretations of what is clearly an inaccurate and incorrect report.

5. Currently the RMAF is examining and analyzing all possibilities as regards to the airliner’s flight paths subsequent to its disappearance. However for the time being, it would not be appropriate for the RMAF to issue any official conclusions as to the aircraft’s flight path until a high amount of certainty and verification is achieved. However all ongoing search operations are at the moment being conducted to cover all possible areas where the aircraft could have gone down in order to ensure no possibility is overlooked.

6. In addition, I would like to state to the media that all information and developments will be released via official statements and press conferences as soon as possible and when appropriate. Our current efforts are focused upon on finding the aircraft as soon as possible.

Thank You

GENERAL TAN SRI DATO’SRI RODZALI BIN DAUD RMAF
Chief of Royal Malaysian Air Force

Crew oxygen supply
 
Are there two completely separate bottles/regs/valves etc, ie independent systems for each pilot?

Is there a portable oxygen supply stowed in the cockpit?

Disc failure unlikely???
One assumes (!) that it was not at take off power when it "vanished", and there is much less stress on most engine components at cruise power
Certainly true, but it certainly can happen. United flight 232 suffered a catastrophic fan disc failure in cruise at FL370.

United Airlines Flight 232 - Wikipedia, the free encyclopedia

DAUD is covering his ass here as reuters reported the story was confirmed by another military source.

Two bottles feeding a common system to both pilots & jump seat occupants. ( I think-it's been a while).

Portable 02 in the cockpit? Not to my knowledge.

777 is a fly-by-wire aircraft
 
If for some reason, all electrical went out to lunch .. all of the major control surfaces might go to neutral? (remember, the 777 is the first fly-by-wire commercial jet) You'd be flying similar to the Sioux City aircraft without hydraulics? Only the engines to control left/right/up/down with? I think you'd have major problems with the up/down .. it might go into a phugoid oscillatory mode. Very difficult to control .. flying low .. you might get an idea of land/water to see where you were, but, you're cooked. You have to figure a place to land, and it's not going to be pretty. But, I'd think that there would be battery power for the critical items .. flight control computers, comm radios? Unless it was some sort of power surge throughout the system?

in my opinion from the little evidence available, it had a depressurisation problem rendering the flight crew and passengers unconscious, resulting in the aircraft flying solely on autopilot and completely unmonitored from the malacca straights on an approximate track taking it over the indian ocean towards the island of madagascar via diago garcia, where at some point it ran out of fuel.

Jabawocky:-

I had the exact same thoughts, same airline same paint removal process

Count Niemantznarr 12th Mar 2014 00:01

Isn't about time all data is transmitted/streamed live from an aircraft, rather than just information on engine condition to the manufacturer? With the AF A330 crash, investigators had a reasonable idea of what happened through the final ACARS messages.

Searching for the CVR and Black Box can be a challenge, in this case, the authorities cannot even find the aircraft!

tartare 12th Mar 2014 00:03

OK.
So the RMAF are now saying they didn't track it westbound?
I'm a little confused.
Without intending to irritate anyone, or appear callous in regard to the souls missing, transponder appears to be located on the pedestal next to the FO's left arm... tries to squawk 7700 while passing out and instead accidentally switches it off...?

prayingmantis 12th Mar 2014 00:06

yep
 
Diego Garcia - now there's a place with limited radar capabilities!!! Surely they would have missed an incursion into their airspace :rolleyes:

Doesn't seem likely. The code change switches have a different and distinctive feel from the mode selector switch.

Very well, my Brother in Law was on that flight. (Assuming you mean the one where the O2 broke loose & ran amok in the cabin before exiting the fuselage). I thought of this in relation to the crew oxy & electronics location question. Massive damage from a rogue cylinder there.

I lean to your theory, although we still haven't been able to rule out foul play, and that the airplane was taken for a reason.

overthewing 12th Mar 2014 00:12


In all these posts, the only real facts known are that the transponder was turned off, the plane turned back, and descended, and was last detected by the military radar westbound until the signal abruptly disappeared.
Do we know that the signal disappeared, or simply left Malaysian radar range?

flt001 12th Mar 2014 00:15

I've completely missed the source saying the military are retracting their statement that the plane changed track westbound. Anyone?

If true it fits into their PR mode of making some vague statement, leaving it one news cycle then retracting said statement.

A320 was the first fly by wire airliner.

B777-You would still have engine driven and air driven hydraulic pumps running.

B777-Spoilers No.4 & No.11 have backup cable controls. So some roll control still.
