Malaysia Airlines plane missing

If a plane of that size is intact (i.e no explosion/fire) but loses all power is there anyway of still operating controls - rudder, ailerons etc- by wire or other mechanical means? And if so, if power was lost at 35000ft how long/far could it get in a controlled or uncontrolled glide?

In the eventuality of a complete power loss from both engines airliners are equipped with an emergency wind driven generator that deploys and provides electrical power.

The news programmes last night were indicating a glide of c90 miles.

The 777 has a 'glide ratio' of something like 17-1... it can glide 17 feet for every 1 foot it descends.

 

So not even half the distance from the reported "last known position" to where the military now say they tracked it to. Rule out my powerless glide theory then.

Not all of them although the 777 does. It's called a ram air turbine, or RAT for short.

 

I doubt gliding came into this. The only things which could knock out both engines on a 777 are fuel starvation, birds, severe icing or volcanic ash. It would take a substantial fuel leak which the crew didn't notice for this flight to have ran out of fuel so early. In any case, the pilots would have broadcast a mayday on HF radio if they were attempting to glide.

Your right Minty . I am probably reading to much into things re passports etc .

 

But if you have a mother already living in Germany why would you need to travel halfway round the world to get a stolen passport to go and see your mum and seek asylum .

 

Meanwhile on news in Scotland it is report via al jeesera. That Iran and not Libya May have been responsible for the Lockerbie flight .

 

A documentary claims to have uncovered fresh evidence that Iran, not Libya, ordered the bombing of Pan Am flight 103 over Lockerbie in December 1988.

Some interesting insight into what could have caused it on http://www.pprune.org (professional pilots rumour network) whee there's a thread looks set to rival the great pompey takeover one. This poster seems to know his sh!t:

 

"CNN have totally bought into the new theory that the plane was tracked on radar into the Straits of Malacca and that it was last radar-fixed at some as yet undisclosed location roughly 100-200 miles northwest of KL.

 

This certainly points to one of two scenarios being more likely than others:

 

1. The pilot, having lost much of his guidance, was attempting to make a visual return to KL. One must then ask if moonset and local weather (something we left behind when it was assumed that the search would be much further north) played any role. METARS for relevant stations might be useful now.

 

2. Hostile elements, either terrorists or misguided pilot(s) were in control of the aircraft and the postulated track would suggest a terror attack planned at KL which after all has some of world's tallest buildings. One might then ask why anyone would plan such a thing especially at night (it would be approximately 0330h to 0400h local time if any terrorists managed to execute such a plan.

 

As either of these seem somewhat difficult to believe, we might then consider a third option, terrorist hi-jack with known landing point in Sumatra, explaining the low-altitude flight path in an attempt to evade primary radar. This even keeps alive the possibility that this plan has been successfully executed but in which case, why no announcement or demands?

 

Most likely outcome, but not by much, is that crippled aircraft made desperate but ultimately unsuccessful attempt to return to KL and that evidence of this will eventually be found."

Interesting theory on this site as well.

That said, if the plane continued flying the you and crossed Malaysia, you would expect another plane to pick up where it is. If it has crossed west and continued flying then it could be anywhere in the Indian Ocean.

Interesting theory which - to the layman - seems plausible.

 

What if - I mean IF - it had lost ability to transmit and carried on on it's original course. How would the Chinese approach an unidentified unresponsive aircraft heading for Beijing? I'm guessing shoot first ask questions later. Could be why thee seem to be getting a bit arsey and keen to lay blame over the whole incident.

Just seen on Sky News

 

Boeing issued a warning about possible fuselage cracking around the radio antenna.

 

Such cracking could firstly cause a slow decompression / lack of Oxygen which could have taken out the crew (eg Payne Stewart)

 

If plane then lost the antenna there would be no comms and if on autopilot with crew gone it could be up to 3,000 miles.

 

More at 6:30 UK time on special report

Eek

 

So there WAS an identified issue with 777's

 

Washington (AFP) - Months before Malaysia Airlines flight MH370 mysteriously vanished, US regulators warned of a "cracking and corrosion" problem on Boeing 777s that could lead to a mid-air breakup and drastic drop in cabin pressure.

 

"We are issuing this AD (Airworthiness Directive) to detect and correct cracking and corrosion in the fuselage skin, which could lead to rapid decompression and loss of structural integrity of the airplane," the Federal Aviation Administration said.

During a sudden drop in cabin pressure, the crew and passengers can become unconscious, leaving no one at the controls of the affected aircraft.

In 1999, a Learjet carrying golfer Payne Stewart crashed into a field in the US state of South Dakota after flying uncontrolled for several hours after those on board apparently became unconscious due to a lack of oxygen brought on by a loss of cabin pressure.

 

A supporting document accompanying the directive indicates that one unidentified operator reported a "16-inch crack" (40.6- centimeter) of the fuselage skin in an aircraft that was 14 years old.

Boeing performed a "metallurgical fracture analysis" of the affected section of the fuselage skin, according to the document

That would rely on a failure of the pressurisation system AND either the flight crew oxygen supply or the cabin altitude warning horn. It would take a highly unlikely coincidence for that to happen. Boeing issue bulletins to operators of their aircraft all the time, I doubt this has anything to do with the accident.

If that was the case, the aircraft would follow its flight planned route, commencing it's approach as close as possible to it's expected approach time. At the same time the crew would set the transponder code to 7600 to alert ATC that they had a loss of communications. The aircraft wouldn't be unidentified as it would be following it's flight plan and still transmitting it's call sign (MAS370).

 

In short, even the Chinese wouldn't have shot this one down.

So there WAS an identified issue with 777's

 

Boeing redesigned the skins of its aircraft after a Hawaiian Airlines 737 was literally ripped apart in mid air by structural fatigue. Amazingly, it went on to land safely, although a flight attendant was sucked out and lost in the accident.

 

Basically the skin is designed to be weaker in a grid like pattern around the fuselage. If a tear occurs, it should in theory travel to the edge of the grid square and along it's edges. If the tear goes undetected, eventually the square will blow out leaving a roughly foot square hole in the fuselage but maintaining the structural integrity of the aircraft.

 

Again, I would be surprised if this was a factor at all. 777s generally operate long haul and are low cycle aircraft, usually only going through 1 or 2 pressurisation cycles (i.e. flights) in a day. Compare that to a low cost short haul aircraft which will usually do around 6 or possibly 8. The Hawaiian accident occurred on a very old aircraft (about 23 years I think) doing high cycles, hopping around the Haiwaiian islands. As such, I would expect the stress fatigue on the skin to be relatively low on the Malaysian aircraft.

 

Plus the effects of pressurisation are well documented, especially after the comet crashes of the 1950s. Designers learned a lot of lessons (mostly from the window edges) from that.

But if I understood it correctly in this scenario it has lost the ability for the transponder and everything else to transmit and crew and passengers are unconscious.

That scenario would require a lot of highly unlikely events to all occur within the time this flight took place. For the flight to have reached cruising altitude, one would have to assume the pressurisation, both VHF transmitters and the transponder were all working correctly. If their was a pressurisation fault, a loud warning horn would have sounded in the cockpit once the cabin altitude rose above 10,000ft and the flight would have turned back and descended. If their had been a communications failure whilst in contact with Malaysian ATC we would know about it by now, likewise with a transponder failure.

 

You would need 2 separate compromises to the fuselage within less than an hour, on an aircraft which has been flying for years. Which would have to occur at the exact points on the fuselage of the 2 VHF antenna. The aircraft is purposely designed with these in separate locations as they do occasionally get damaged by birds or lightning. Add to that a transponder failure AND a failure of the cabin altitude warning system, which are all completely separate from each other. It's like buying winning lottery tickets in 4 different lotteries in the same week.

 

Who do you fly for Lighthouse?

 

I don't want to put it on here but it is a well known European airline.

If everybody was unconscious nothing would change. The transponder would stay on it's original selection. However in the cabin the Oxygen masks would drop as the cabin altitude increased, the crew have portable Oxygen bottles. The pilots have masks that can be inflated and put on in seconds. Emergency descents are practiced regularly in the simulator. I used to mentally run through all the memory items while in the cruise every day I flew. Only took about 5 mins reading the Check List and looking at the relevant controls.

 

A King Air was lost on a test flight from Southern England and crashed in Brittany after running out of fuel. One of our crews positioned from Orlando to Cancun in Payne Stewart's Learjet just before the loss. I asked the Captain where were the Oxygen masks and he said he was never told!! It sounded like a sloppy operation.

Cheers. Comprehensive answer . I did say it sounded plausible to a layman lol. Cross that one off the list of possibilities then.

BBC news still running with the news that large amounts of debris have been sighted by a Chinese satellite yet other news channels are discounting this including the Chinese

 

The beeb are so crap. With their news reporting .

That's a bit unfair. They're right on the button with anything and everything that happens globally, as long as it happens between 9.00 and 17.00 UK time Monday to Friday, and has a disabled minority feminist angle to it.

I know there are ranks out there but the authorities should not dismiss them out if hand . It's quite feasible that the guy on the rig did see something .. If they extend the search area any further then they will be searching the likes I of the Indian Ocean .

 

If it's at the bottom of the sea somewhere then that could take weeks to find . But I guess there's several subs scanning the ocean bed as I type .

 

The film moguls will do a drama film about it in the years ahead .

The flight will probably appear on radar and land 'on time' exactly a week later. Nobody on board will have any idea that anything is wrong.

I have know idea what happened just speculating on the various threads that exist . I appreciate the knowledge of our resident genuine pilots on here re how an aircraft might behave

 

One piece of information and pun intended . Is the fact there will be alsorts of debris floating in the sea around the works following the Japanese tsunami . Larger boats recently being washed up in the states and an even big vessel floating aimlessly in the seas . Last reported somewhere in the Atlantic if I remember correctly . So it is possible that the satellite imagery my be from the tsunami and not the aircraft

The mystery surrounding the fate of the Malaysia Airlines plane which went missing almost six days ago has deepened amid claims that satellites were still receiving data from the aircraft after it went missing.

A source close to the investigation has said the flight MH370, which was travelling from Kuala Lumpur to Beijing with 239 on board, sent a brief signal, or 'ping', to satellites in space after it had lost contact with ground control.

The development comes as Malaysian authorities attempted to downplay the theories springing up around the fate of the aircraft, and as the U.S. confirms it could start searching the Indian Ocean for debris - rather than the South China Sea.

An Indonesian Air Force officer draws a flight pattern flown earlier in a search operation for the missing Malaysia Airlines Boeing 777, during a post-mission briefing at Suwondo air base in Medan, North Sumatra, Indonesia

 

The 'ping' is not through to have contained any information about the condition or trajectory of the plane, but merely to confirm that the aircraft existed and that it was possible to contact it.

The system transmits such pings about once an hour, sources said, but it remains unclear how many signals the plane sent after air traffic control lost track of it.

 

Boeing Co, which made the missing 777 airliner, and Rolls-Royce, which supplied its Trent engines, declined to comment.

 

Earlier Malaysian officials denied reports that the aircraft had continued to send technical data after losing contact.

 

Meanwhile Malaysian authorities expanded their search westward towards India today, and a senior Pentagon official suggested there was 'an indication' the plane came down in the Indian ocean.

 

 

 

 

 

 

 

Responding to the new theory that the Malaysian Airlines flight may have come down in the Indian Ocean, rather than the South China Sea, the U.S. Navy has allegedly sent its own resources there.

U.S destroyer USS Kidd is now reportedly being moved in to search the area, while Malaysia was due to ask for radar data from India and other neighbouring countries to see if they can trace the plane flying north west.

This evening a White House spokesperson conceded the possibility of a new search, saying 'new information' prompted the move. He did not make clear what the information was.

 

'It's my understanding that based on some new information that's not necessarily conclusive - but new information - an additional search area may be opened in the Indian Ocean,'White House spokesman Jay Carney said. 'And we are consulting with international partners about the appropriate assets to deploy.'

 

'We're looking at information, pursuing possible leads, working within the investigation being led by the Malaysian government,' Carney added.

 

Meanwhile, India plans to imminently deploy planes and ships in the southern section of the sea, a senior Indian official said on condition of anonymity because he was not authorised to speak to the media.

The senior Pentagon official reportedly told ABC News it would take 24 hours for USS Kidd to be moved into position.

Six days on and a massive international air and water search involving 10 nations using 56 surface ships has failed to find a single piece of debris or sign of the Malaysian Airlines aircraft

 

 

Flight 370: "We found nothing" says Malaysian minister

Earlier, Malaysian defence minister Hishammuddin Hussein described reports suggesting the jetliner kept flying for four hours after it vanished as 'inaccurate' and said satellite images showing suspected debris of the crash had been released 'by mistake'.

The plane left Kuala Lumpur and was flying northeast across the Gulf of Thailand and into the South China Sea when it dropped off civilian radar without any indication it was having any technical problems.

It's quite funny. Haven't really participated in this thread but am amazed that people have been able to generate so much content with so little evidence.

 

The mainboard is exactly the same.

 

Most people on this board are conspiracy theorists; some just have a wider range than others :)

The presence on board this flight of more than 20 employees of an American electronic warefare company may possibly have something to do with its disappearance. I don't believe it has simply fallen from the sky, I suspect that it has been diverted to somewhere, where the knowledge of these people can be harvested freely. Hence the 'confusion' from the media and the various governments involved.

Why the Andaman Islands or another remote area? Some theories related to hijacking mention the plane could have been landed somewhere with the intention of using it for other purposes. There is an airport on Andaman, which is in the hands of the Indian Navy but if such a scenario happened a landing would have needed to be somewhere remote where it wouldn't be detected easily. Indonesia, seems the more likely destination in a hijacking scenario. where a refueling could be carried out and the passengers offloaded. Perhaps some Muslim extremists have control of some remote airport or runway.

 

List of Indonesian airports ( quite a large choice!!)

My theory for what it's worth......

 

Onboard explosion of some sort/depressurization. Knocks out comms to the ground; pilots drop altitude and head back to KL; pass out through lack of oxygen; plane keeps flying west until out of fuel.

 

They'll find it in the Indian Ocean. The Yanks know where it is right now; they are feeding info out to the press in a way that will prevent them clarifying how they know it, and help Malaysian officials regain some face.

 

Note the stuttered wording of the Malaysian press conference: new information; protecting our national security; working with partners. Balls. USA is proactively guiding them to the spot in the Indian Ocean.

If it was flying west'ish for 5 hours it wouldn't be far from Diego Garcia (or in theory anyway). They'd know of any unidentified

aircraft that came within 1000 miles or so of there so yes they might well know exactly where it was if that case scenario

should have happened.
