Did Malaysian plane fly toward Indian Ocean after last contact?
Last Updated Mar 13, 2014 7:04 PM EDT
KUALA LUMPUR, Malaysia -- Malaysian authorities expanded their search for the missing jetliner westward toward India on Thursday, saying it may have flown for several hours after its last contact with the ground.
CBS News correspondent Bob Orr reports that there are technical indicators suggesting the plane continued to fly for an unspecified period of time after civilian air traffic controllers lost radar contact with the jet. Sources say the Boeing 777 continued to attempt to transmit routine data about the plane's engines and performance to satellites. Malaysian authorities and Boeing apparently did not downlink the data, so details from plane's transmissions are not known.
But, the fact that the jet was continuing to send signals is a strong indication that the jet did not crash immediately after radar contact was lost. The engines instead continued to run, Orr reports, meaning the plane continued in flight or perhaps was on the ground but still producing power.
In addition, U.S. radar experts have looked at the Malaysian military radar track, which seemed to show the jet flying hundreds of miles off course west of its flight path, and back across the Malaysian peninsula. Sources say the radar appears to be legitimate and there is a strong reason to suspect that the unidentified blips - seen on military controller screens - are images of Malaysian Airlines 370.
All of this, Orr reports, is leading to the possibility that the jet flew for hours toward the Indian Ocean. And it is the reason the search field is expanding in that direction. [...]
The Wall Street Journal newspaper quoted U.S. investigators on Thursday as saying they suspected the plane remained in the air for about four hours after its last confirmed contact, citing data from the plane's engines that are automatically transmitted to the ground as part of a routine maintenance program.
"This opens up a whole host of new questions," CBS News aviation and safety expert Captain Chesley "Sully" Sullenberger said on "CBS This Morning."
"There's still much we don't know," said Sullenberger, explaining that only Boeing, or the manufacturer of the engines on the aircraft, Rolls Royce, could confirm or deny the report.
Hishammuddin said the government had contacted Boeing and Rolls Royce, the engine manufacturer, and both said the last engine data was received at 1:07 a.m., around 23 minutes before the plane's transponders, which identify it to commercial radar and nearby planes, stopped working.
Two sources close to the investigation told Reuters that Boeing and Rolls-Royce did not receive any maintenance data from the jet after the point at which its pilots last made contact.
CBS News contacted Rolls Royce twice on Thursday morning at the company's U.K. headquarters. The company refused to comment on the Wall Street Journal report.
Aviation experts tell CBS News the engine data would have been transmitted to Malaysia Airlines ground control, and then possibly on to Rolls Royce, by a decades-old system known as ACARS. The simple data transmission system is widely used in commercial aviation, and sends automated messages on virtually every operating system on an aircraft to the ground at regular intervals.
According to an article in the New Scientist, published on Tuesday, the Boeing 777-200 that left Kuala Lumpur for Flight 370 sent just two ACARS data transmissions to the ground, one just after takeoff and a second after it reached cruising altitude. The article did not mention any further transmissions. [...]

Malaysian plane sent out engine data before vanishing
* 17:23 11 March 2014 by Paul Marks
The missing Malaysia Airlines jet sent at least two bursts of technical data back to the airline before it disappeared, New Scientist has learned. The data may help investigators understand what went wrong with the aircraft, no trace of which has yet been found.
To aid maintenance, most airlines use the Aircraft Communications Addressing and Reporting System (ACARS), which automatically collates and files four technical reports during every flight so that engineers can spot problems. These reports are sent via VHF radio or satellite at take-off, during the climb, at some point while cruising, and on landing.
Malaysia Airlines has not revealed if it has learned anything from ACARS data, or if it has any. Its eleventh media statement since the plane disappeared said: "All Malaysia Airlines aircraft are equipped with... ACARS which transmits data automatically. Nevertheless, there were no distress calls and no information was relayed."
This would suggest no concrete data is to hand. But New Scientist understands that the maker of the missing Boeing 777's Trent 800 engines, Rolls Royce, received two data reports from flight MH370 at its global engine health monitoring centre in Derby, UK, where it keeps real-time tabs on its engines in use. One was broadcast as MH370 took off from Kuala Lumpur International Airport, the other during the 777's climb out towards Beijing. [...]

By RJohnson_dt | Posted: March 14, 2014
ROLLS-ROYCE has backed the Malaysian government's dismissal of media reports over the missing passenger plane.
The reports suggested that engine data gathered by Rolls-Royce showed that the missing Malaysia Airlines jet may have flown on for hours after it vanished from radar screens.
On Thursday, The Wall Street Journal ran a report claiming that US aviation investigators and national security officials believed the plane flew for a total of five hours, based on data automatically downloaded and sent to the ground from the Boeing 777's Rolls-Royce engines.
Flight MH370, which was fitted with two Derby-built Rolls-Royce Trent 800 engines, has been missing for more than a week now. [...]
But Malaysian Transport Minister Hishammuddin Hussein was quick to dismiss the report, saying it was "inaccurate".
He said the last transmission from the aircraft indicated that everything was normal.
He said: "Rolls-Royce and Boeing teams are here in Kuala Lumpur and have worked with the investigations team since Sunday.
"Whenever there are new details, they must be corroborated. Since these media reports, Malaysia Airlines has asked Rolls-Royce and Boeing specifically about this data. As far as Rolls-Royce and Boeing are concerned, those reports are inaccurate."
In a statement, Rolls-Royce said: "Rolls-Royce concurs with the statement made on Thursday by Malaysia's Transport Minister Hishammuddin Hussein regarding engine health monitoring data received from the aircraft.
"Rolls-Royce continues to provide its full support to the authorities and Malaysia Airlines." [...]

System and method for automatically controlling a path of travel of a vehicle
Abstract
The method and system for automatically controlling a path of travel of a vehicle include engaging an automatic control system when the security of the onboard controls is jeopardized. Engagement may be automatic or manual from inside the vehicle or remotely via a communication link. Any onboard capability to supersede the automatic control system may then be disabled by disconnecting the onboard controls and/or providing uninterruptible power to the automatic control system via a path that does not include the onboard accessible power control element(s). The operation of the vehicle is then controlled via the processing element of the automatic control system. The control commands may be received from a remote location and/or from predetermined control commands that are stored onboard the vehicle.

Raytheon and Air Force Demonstrate Civil-Military Interoperability for GPS-Based Precision Auto-Landing System.
MARLBOROUGH, Mass., Oct. 1 /PRNewswire/ --
A government-industry team accomplished the first precision approach by a civil aircraft using a military Global Positioning System (GPS) landing system on Aug. 25 at Holloman AFB, N.M., Raytheon Company (NYSE: RTN) announced today. A FedEx Express 727-200 Aircraft equipped with a Rockwell-Collins GNLU-930 Multi-Mode Receiver landed using a Raytheon-developed military ground station. Raytheon designed and developed the differential GPS ground station under an Air Force contract for the Joint Precision Approach and Landings System (JPALS) program. The JPALS system is being developed to meet the Defense Department's need for an anti-jam, secure, all weather Category II/III aircraft landing system that will be fully interoperable with planned civil systems utilizing the same technology. Raytheon and the U.S. Air Force have been conducting extensive flight testing for JPALS at Holloman over the last three months. The FedEx Express 727-200 aircraft at Holloman successfully conducted a total of sixteen Category I approaches. After completing a number of pilot flown approaches for reference the aircraft conducted six full autolands using the JPALS ground station. "The consistency of the approaches allowed us to proceed to actual autolandings with very little delay," said Steve Kuhar, Senior Technical Advisor Flight Department for FedEx Express. The aircraft was guided by differential GPS corrections, integrity information, and precision approach path points transmitted from the Raytheon developed JPALS ground station. Although the approaches were restricted to Category I, accuracies sufficient to meet Cat II/III requirements were observed. Raytheon is the world leader in designing and building satellite-based navigation and landing solutions for civil and military applications. In addition to developing JPALS for the Department of Defense, Raytheon is also developing both the Local Area Augmentation System (LAAS) and the Wide Area Augmentation System (WAAS) for the Federal Aviation Administration. The JPALS and LAAS will provide an interoperable landing capability for military and civil applications. "Raytheon is committed to developing and deploying satellite based navigation and landing systems for the military and the flying public," said Bob Eckel, Raytheon vice president for Air Traffic Management. "We understand the importance of this technology and are proud to be a part of the success achieved this summer during JPALS testing at Holloman." With headquarters in Lexington, Mass., Raytheon Company is a global technology leader in defense, government and commercial electronics, and business and special mission aircraft. [...]

(24) Boeing 777 features digital fly-by-wire controls & software-configurable avionics
http://en.wikipedia.org/wiki/Boeing_777
Boeing introduced a number of advanced technologies with the 777 design, including fully digital fly-by-wire controls, fully software-configurable avionics, Honeywell LCD glass cockpit flight displays, and the first use of a fiber optic avionics network on a commercial airliner. Boeing made use of work done on the cancelled Boeing 7J7 regional jet, which utilized similar versions of the chosen technologies. In 2003, Boeing began offering the option of cockpit electronic flight bag computer displays. In 2013, Boeing announced that the upgraded 777X models would incorporate airframe, systems, and interior technologies from the 787.

MH370 search: Boeing has patent for autopilot tech
Sira Habibu
The Star/Asia News Network
Saturday, Apr 12, 2014
PETALING JAYA - When it was first speculated that Flight MH370 could have been hijacked via remote control access, many dismissed it as far-fetched science fiction.
But the technology to navigate planes, ships, trains, buses and other vehicles by remote control has been around for about a decade.
The Boeing Company, the world's leading aerospace company and the largest manufacturer of commercial jetliners and military aircraft, has the technology.
It owns a patent for a system that enables remote controlling of its aircraft to counter hijacking attempts.
Boeing applied for the patent for an "uninterruptible autopilot control system" about 11 years ago, and was awarded it in 2006.
The system can be activated when the security of onboard controls are jeopardised.
"The method and systems of the present invention provide techniques for automatically navigating, flying and landing an air vehicle," states the report for the US patent number US7142971B2.
Once activated, an aircraft could be automatically navigated, flown and made to land without input from anyone on board.
"Any onboard capability to supercede the automatic control system may be disabled by disconnecting the onboard controls," states the report.
Power is provided to the automatic control system "from an alternative power control element that is inaccessible (to anyone on board the vehicle)".
According to the patent report, control commands could be received from a remote location and/or from predetermined control commands stored on board the plane.
Boeing applied for the patent on Feb 19, 2003, barely two years after the Sept 11 attack in which hijacked planes rammed into the World Trade Centre, reducing the gigantic buildings into rubble.
Eric D. Brown, Douglas C. Cameron, Krish R. Krothapalli, Walter von Klein Jr and Todd M. William invented the system for Boeing. The patent was awarded three years later on Nov 28, 2006.
When the automatic control system is activated, no one on board the aircraft would be capable of controlling its flight.
The patent report also states that a signal might be transmitted to at least one remote location from the plane to indicate that the uninterruptible autopilot mode of the air vehicle has been engaged.
The system includes a dedicated communication link between the aircraft and a remote location, distinct from any communication link established for other types of communication.
According to an independent analyst James Corbett, the US Federal Aviation Administration had reported on the Federal Registrar last November that the Boeing 777-200, -300 and -300ER aircraft were equipped with an electronics security system to check unauthorised internal access.

Emirates' Clark Sees MH370 Investigation Deficiencies
Jun 3, 2014 Jens Flottau | AWIN First
Emirates Airline President Tim Clark is demanding more transparency in the investigation of the disappearance of Malaysia Airlines flight MH370. "We are the largest operator of the Boeing 777 in the world. I need to know how anybody could interdict our systems," Clark told Aviation Week in an interview on the sidelines of the International Air Transport Association's (IATA) annual general assembly in Doha, Qatar. "Something is not right here and we need to get to the bottom of it."
Clark criticized how the investigation into the disappearance of the Malaysian Boeing 777 has been handled. "There have been many questions unanswered or dealt with in a manner that is unacceptable to the forensic nature of the inquiry." He believes that "this aircraft was disabled in three primary systems. To be able to disable those requires a knowledge of the system which even our pilots in Emirates don't know how to do. Somebody got on board and knew exactly what they were up to."
Clark also does not believe that the aircraft was not seen when it flew over land in Malaysia after its initial unplanned left turn. "The notion that the track of an aircraft going across the Malaysian peninsula was not picked up on primary radar, sorry, I don't subscribe to that view."
The Emirates President is also skeptical about the industry initiatives on flight tracking. "We have never lost an aeroplane in 50 years, we have always known where they are. Whoever was clever enough to interdict the system, will be able to interdict this one as well." To Clark, tracking is not the main issue: "the first thing you need to do is do not allow anybody on board to disable ACARS - job done."

Malaysia Airlines flight MH370: Stricken plane was 'thrown around like a fighter jet in attempt to dodge radar'
Investigators now convinced that plane was 'flown very low at a very high speed' in bid to avoid radar detection, source claims
TOMAS JIVANDA
Sunday 13 April 2014
The missing Malaysia Airlines flight was “thrown around like a fighter jet” in a bid to dodge radar detection after it disappeared, Malaysian military investigators reportedly now believe.
An unnamed source cited by The Sunday Times added that officials are now convinced that the plane was “flown very low at a very high speed”.
The source concluded: “And it was being flown to avoid radar.”
It is also possible that the flight surged to 45,000 feet - 10,000 above its normal cruising altitude of 35,000 feet - after disappearing, before dropping to as low as 5000 feet, reports by investigators have suggested.
The low altitude would fit in with a report by Malaysia’s New Straits Times newspaper that co-pilot Fariq Abdul Hamid tried to make a mid-flight phone call shortly before the plane disappeared.
In order for the phone signal to reach the reported telecommunications tower near the Malaysian city of Penang, the plane would needed to have been flying under 7000 feet.
The newspaper report said the signal ended abruptly before contact was established.

MH370: New evidence of cockpit tampering as investigation into missing plane continues
Investigations into the missing Malaysia Airlines flight MH370 have revealed apparent tampering of systems in the cockpit
By Jonathan Pearlman, Sydney
2:26PM BST 29 Jun 2014
Air crash investigators probing the disappearance of Malaysia Airlines MH-370 have discovered possible new evidence of tampering with the plane's cockpit equipment.
A report released by Australian air crash investigators has revealed that the missing Boeing 777 suffered a mysterious power outage during the early stages of its flight, which experts believe could be part of an attempt to avoid radar detection.
According to the report, the plane's satellite data unit made an unexpected "log-on" request to a satellite less than 90 minutes into its flight from the Malaysian capital, Kuala Lumpur, to the Chinese city of Beijing. The reports says the log-on request - known as a "handshake" - appears likely to have been caused by an interruption of electrical power on board the plane.
"A log-on request in the middle of a flight is not common," said the report, by the Australian Transport Safety Bureau. "An analysis was performed which determined that the characteristics and timing of the logon requests were best matched as resulting from power interruption."
David Gleave, an aviation safety expert from Loughborough University, said the interruption to the power supply appeared to be the result of someone in the cockpit attempting to minimise the use of the aircraft's systems. The action, he said, was consistent with an attempt to turn the plane's communications and other systems off in an attempt to avoid radar detection.
"A person could be messing around in the cockpit which would lead to a power interruption," he said. "It could be a deliberate act to switch off both engines for some time. By messing about within the cockpit you could switch off the power temporarily and switch it on again when you need the other systems to fly the aeroplane."
Inmarsat, the company that officially analysed flight data from MH370, has confirmed the assessment but says it does not know why the aircraft experienced a power failure.
"It does appear there was a power failure on those two occasions," Chris McLaughlin, from Inmarsat, told The Telegraph. "It is another little mystery. We cannot explain it. We don't know why. We just know it did it."
The Australian report released by Australian authorities has revealed that the Boeing 777 attempted to log on to Inmarsat satellites at 2.25am, three minutes after it was detected by Malaysian military radar.
This was as the plane was flying north of the Indonesian island of Sumatra. The aircraft had already veered away from the course that would have taken it to its destination of Beijing, but had not yet made its turn south towards the Indian Ocean.
The aircraft experienced another such log-on request almost six hours later, though this was its seventh and final satellite handshake and is believed to have been caused by the plane running out of fuel and electrical power before apparently crashing, somewhere in the southern Indian Ocean. The other five handshakes were initiated by the satellite ground station and were not considered unusual.
Asked whether the power interruption could have been caused by a mechanical fault, Mr Gleave said: "There are credible mechanical failures that could cause it. But you would not then fly along for hundreds of miles and disappear in the Indian Ocean."
Another aviation expert, Peter Marosszeky, from the University of New South Wales, agreed, saying the power interruption must have been intended by someone on board. He said the interruption would not have caused an entire power failure but would have involved a "conscious" attempt to remove power from selected systems on the plane.
"It would have to be a deliberate act of turning power off on certain systems on the aeroplane," he said. "The aircraft has so many backup systems. Any form of power interruption is always backed up by another system.
"The person doing it would have to know what they are doing. It would have to be a deliberate act to hijack or sabotage the aircraft."
An international team in Malaysia investigating the cause of the crash has not yet released its findings formally, but has indicated it believes the plane was deliberately flown off course. The plane disappeared on March 8 with 239 passengers aboard but an international air, sea and underwater search has failed to find any wreckage.
The Australian report added that the plane appeared to have flown on autopilot across the Indian Ocean and that the crew and passengers were likely to have been unresponsive due to lack of oxygen during the southward flight.
It has recommended an underwater search in an area about 1,100 miles west of Australia, around the location where the plane's seventh "handshake" is believed to have occurred.
The report also notes that the plane's in-flight entertainment system delivered a satellite message 90 seconds after the first power failure but not after the second failure hours later. This, it says, "could indicate a complete loss of generated electrical power shortly after the seventh handshake".
The new underwater search will begin in August and cover about 23,000 square miles. It is expected to take up to a year.

Near-conclusive evidence that Malaysia Airlines MH370 was hijacked: cockpit tampering deliberately hid plane from radar
Tuesday, July 01, 2014
by Mike Adams, the Health Ranger
(NaturalNews) New evidence is now emerging that Malaysia Airlines flight 370 was almost certainly hijacked. This is now readily apparent from the fact that the aircraft cockpit electrical systems were tampered with, reports the Telegraph. (1) [...]
How transponders and squawk codes work
When aircraft clear departure at a large airport, the departure controllers give them a "squawk" code to enter into their transponders. Squawk codes are 4-digit codes such as 0251.
Once the pilot enters this code into their transponder, Air Traffic Control (ATC) sees that squawk code number assigned to that plane's icon on their radar screen. Heading and altitude information will also be shown next to the squawk code.
A commercial airline pilot would never voluntarily turn off their transponder. Flying without a transponder not only makes you invisible to ATC, it also makes you invisible to other nearby planes which can hit you mid-air, especially when flying in or out of busy airport traffic patterns. As a bonus, it also gets your commercial pilot's license yanked by the FAA or other aviation authorities. Switching off a transponder puts all the lives of the crew and passengers at risk.
The fact that the MH370 transponder was switched off almost certainly means the airplane was hijacked by someone who knew how to hide the plane from radar. The plane was then flown for many hours afterward, according to satellite signals. This also means there was a deliberate attempt to transport the plane to another location, not to dump it in the ocean as is thoughtlessly suggested by mainstream media. (Nobody goes to the trouble of hiding a plane from ATC radar and flying it for seven hours just to dump it in the ocean.)
The fact that the transponder was powered off also means the hijacker(s) were very technically educated about aircraft and transponders. They knew how to disable the electrical subsystem, in other words. That takes specialized knowledge that "ordinary" hijackers wouldn't know.
Yet more proof of the hijacking: emergency squawk codes were not used
Want even more proof that the plane was hijacked and didn't just suffer a radio communications failure of some kind?
All commercial airline pilots are taught to memorize so-called emergency squawk codes. These include:
7500 Hijack in progress
7600 Communications failure
7700 In-flight emergency
7777 Military intercept
Had this plane suffered a com failure that took out its radios, the pilot would have simply squawked 7600 and ATC would have known the com units had failed, but the plane could still be flown.
Had the plane been hijacked by an "ordinary" hijacker with little aviation knowledge, the pilot could have covertly entered a squawk code of 7500, indicating a hijacking. This only requires entering the four digits on a small keypad typically located near the Primary Function Display (PDF).
IMMARSAT FALSE TRAILS
(31) MH370: Australian navy admits it followed a false trail of pings

MH370: Australian navy followed false trail in search for missing plane
May 30, 2014
The exposure of a false trail of pings has led to experts abandoning a search area identified as the final resting place of Malaysia Airlines flight MH370, calling into question two months of search efforts.
The area in the Indian Ocean became the focus of international attention on April 11 after the Prime Minister, Tony Abbott, announced he was confident signals had been detected from MH370's black box, narrowing the search to an 850-square kilometre zone.
But on Thursday Deputy Prime Minister Warren Truss went before Parliament to say the ''pings'' were the best information the government had at the time but ''the area can now be discounted''.
Mr Truss said a ''painstaking'' search of an area up to 60,000 square kilometres would now follow an oceanographic survey of the sea floor and an extensive review of all data available surrounding the plane's disappearance.
He made the announcement after Australian aviation authorities declared the plane was not in the Indian Ocean search zone where the pings were detected, and warned a revised search could take more than a year.
''The Australian Transport Safety Bureau (ATSB) has advised that the search in the vicinity of the acoustic detections can now be considered complete and in its professional judgment, the area can now be discounted as the final resting place of MH370,'' the Joint Agency Co-ordination Centre said on Thursday.

The official word came after a US Navy official told CNN this morning that the pings are now universally believed to have come from a man-made source unrelated to the missing jetliner, and not from the plane’s data or cockpit voice recorders.
Michael Dean, the Navy’s deputy director of ocean engineering, said that if the pings had come from the recorders, searchers would have found them.
“Our best theory at this point is that (the pings were) likely some sound produced by the ship ... or within the electronics of the Towed Pinger Locator,” Dean said.
“Always your fear any time you put electronic equipment in the water is that if any water gets in and grounds or shorts something out, that you could start producing sound.”

Why the Official Explanation of MH370's Demise Doesn't Hold Up
Outside satellite experts say investigators could be looking in the wrong ocean.

Investigators searching for the missing Malaysian Airlines flight were ebullient when they detected what sounded like signals from the plane's black boxes. This was a month ago, and it seemed just a matter of time before the plane was finally discovered.
But now the search of 154 square miles of ocean floor around the signals has concluded with no trace of wreckage found. Pessimism is growing as to whether those signals actually had anything to do with Flight 370. If they didn't, the search area would return to a size of tens of thousands of square miles.
Even before the black-box search turned up empty, observers had begun to raise doubts about whether searchers were looking in the right place. Authorities have treated the conclusion that the plane crashed in the ocean west of Australia as definitive, owing to a much-vaunted mathematical analysis of satellite signals sent by the plane. But scientists and engineers outside of the investigation have been working to verify that analysis, and many say that it just doesn't hold up. [...]
Inmarsat concluded that the flight ended in the southern Indian Ocean, and its analysis has become the canonical text of the Flight 370 search. It’s the bit of data from which all other judgments flow—from the conclusive announcement by Malaysia’s prime minister that the plane has been lost with no survivors, to the black-box search area, to the high confidence in the acoustic signals, to the dismissal by Australian authorities of a survey company’s new claim to have detected plane wreckage.
Although Inmarsat officials have described the mathematical analysis as "groundbreaking," it's actually based on some relatively straightforward geometry. Here’s how it works: Every so often (usually about once an hour), Inmarsat’s satellite sends a message to the plane’s communication system, asking for a simple response to show that it’s still switched on. This response doesn’t specify the plane’s location or the direction it's heading, but it does have some useful information that narrows down the possibilities.
You can think of the ping math like a game of Marco Polo played over 22,000 miles of outer space. You can’t see the plane. But you shout Marco, and the plane shouts back Polo. Based on how long the plane takes to respond, you know how far away it is. And from the pitch of its voice, you can tell whether it’s moving toward you or away from you—like the sound of a car on the highway—and about how fast.
This information is far from perfect. You know how far the plane was for each ping, but the ping could be coming from any direction. And you how fast the plane is moving toward or away from you. It could also be moving right or left, up or down, and the speeds would sound the same. The task of the Inmarsat engineers has been to take these pieces and put them together, working backwards to reconstruct possible flight paths that would fit the data.
What’s the Frequency?
There are two relevant pieces of information for each ping: the time it took to travel from plane to satellite, and the radio frequency at which it was received. It’s important to keep in mind that the transit times of the pings correspond to distances between satellite and plane, while frequencies correspond to relative speeds between satellite and plane. And this part’s critical: Relative speed isn’t the plane’s actual airspeed, just how fast it’s moving toward or away from the satellite.
Authorities haven't released much information about the distances--just the now-famous "two arcs" graphic, derived in part from the distance of the very last ping. But they've released much more information about the ping frequencies. In fact, they released a graph that shows all of them:
Inmarsat
This graph is the most important piece of evidence in the Inmarsat analysis. What it appears to show is the frequency shifts or "offsets"--the difference between the normal "pitch" of the plane's voice (its radio frequency) and the one you actually hear.
{visit the webpage to see the diagrams}
The graph also shows the shifts that would be expected for two hypothetical flight paths, one northbound and one southbound, with the measured values closely matching the southbound path. This is why officials have been so steadfastly confident that the plane went south. It seems to be an open-and-shut verdict of mathematics.
So it should be straightforward to make sure that the math is right. That’s just what a group of analysts outside the investigation has been attempting to verify. The major players have been Michael Exner, founder of the American Mobile Satellite Corporation; Duncan Steel, a physicist and visiting scientist at NASA’s Ames Research Center; and satellite technology consultant Tim Farrar. They’ve used flight and navigation software like STK, which allows you to chart and make precise calculations about flight scenarios like this one. On their blogs and in an ongoing email chain, they’ve been trying to piece together the clues about Flight 370 and make sense of Inmarsat’s analysis. What follows is an attempt to explain and assess their conclusions.
What We Know
Although the satellite data provides the most important clues about the plane’s overall flight path, they’re not the only clues available. Authorities have some basic but crucial additional information about the flight that can help to make sense of the satellite math:
1. The satellite’s precise coordinates
The satellite in contact with Flight 370 was Inmarsat’s IOR satellite, parked in geostationary orbit above the Indian Ocean. The satellite is meant to be stationary, but its orbit has decayed somewhat, so that it actually rotates slightly around its previously fixed position. Its path is publicly available from the Center for Space Standards & Innovation.
2. The plane’s takeoff time and coordinates
16:41 UTC from the Kuala Lumpur airport.
3. The plane’s general motion toward or away from the satellite
From radar tracking, we know the plane traveled northeast, away from the satellite, over the first 40 minutes after takeoff, then westward, toward the satellite, until 94 minutes into the flight, when it was last detected on radar. Inmarsat spokesmen have stated that the ping distances got progressively longer over the last five hours of flight, meaning that the plane was moving away from the satellite during that time.
4. Two flight paths investigators think are consistent with the ping data
In addition to the frequency shift graph, the Inmarsat report includes a map with two “Example Southern Tracks,” one assuming a flight speed of 400 knots, the other a speed of 450 knots.
These bits of knowledge allow us to put some basic constraints on what a graph of the ping frequency shifts should look like. We’ll use more precise numbers later; for now, it’s helpful just to have some qualitative sense of what to expect:
5. Frequency shifts that should all be negative
When the plane is moving away from the satellite, the radio signal gets stretched out, so the frequency decreases. This means that the frequency shifts should be negative over most of the flight. Although there was an approximately one-hour period starting 40 minutes after takeoff when radar showed the plane moving westward, toward the satellite, the graph shows that no pings were sent during that time—so actually, all of the shifts on the graph should be negative.
6. Frequency shifts before takeoff that should be near zero
Plotting the satellite’s path in STK, you can see that it moves through an ellipse centered around the equator. Space scientist Steel has created this graphic of the satellite’s motion, including marks for its position when the plane took off and when it last pinged the satellite:
The satellite’s motion is almost entirely north-south, and the plane’s takeoff location in Kuala Lumpur is almost due east of the satellite. This means that the satellite was only barely moving relative to Kuala Lumpur, so the frequency shift for a plane nearly stationary on the ground at the airport would be nearly zero.
7. Frequency shift graph should match map of southbound flight paths
The way the Marc-Polo math works is that, if you assume the plane traveled at some constant speed, you can produce at most one path north and one path south that fit the ping data. As the example flight paths on Inmarsat’s map show, the faster you assume the plane was moving overall, the more sharply the path must arc away from the satellite.
This constraint also works the other way: Since flight paths for a given airspeed are unique, you can work backwards from these example paths, plotting them in STK to get approximate values for the ping distances and relative speeds Inmarsat used to produce them. The relative speeds can then be converted into frequency shifts, which should roughly match the values on the frequency graph. (This is all assuming that Inmarsat didn’t plot the two example paths at random but based on the ping data.) We’ll put more precise numbers on this below.
The Troubled Graph
But the graph defies these expectations. Taken at face value, the graph shows the plane moving at a significant speed before it even took off, then moving toward the satellite every time it was pinged. This interpretation is completely at odds with the official conclusion, and flatly contradicted by other evidence.
The first problem seems rather straightforward to resolve: the reason the frequency shifts aren't negative is probably that Inmarsat just graphed them as positive. Plotting absolute values is a common practice among engineers, like stating the distance to the ocean floor as a positive depth value rather than a negative elevation value.
But the problem of the large frequency shift before takeoff is more vexing. Exactly how fast does the graph show the plane and satellite moving away from each other prior to takeoff? The first ping on the graph was sent at 16:30 UTC, eleven minutes prior to takeoff. The graphed frequency shift for this ping is about -85 Hz. Public records show that the signal from the plane to the satellite uses a frequency of 1626 to 1660 MHz. STK calculations show the satellite’s relative motion was just 2 miles per hour toward the airport at this time. Factoring in the satellite’s angle above the horizon, the plane would need to have been moving at least 50 miles per hour on the ground to produce this frequency shift—implausibly high eleven minutes prior to takeoff, when flight transcripts show the plane had just pushed back from the gate and not yet begun to taxi.
On the other side of the frequency graph, the plane’s last ping, at 00:11 UTC, shows a measured frequency shift of about -252 Hz, working out to a plane-to-satellite speed of just 103 miles per hour. But the sample southbound paths published by Inmarsat show the plane receding from the satellite at about 272 miles per hour at this time.
In other words, the frequency shifts are much higher than they should be at the beginning of the graph, and much lower than they should be at the end. Looking at the graph, it’s almost as if there’s something contributing to these frequency shift values other than just the motion between the satellite and the plane.
Cracking the 'Doppler Code'
Exner, an engineer who’s developed satellite and meteorology technologies since the early 1970s, noted that the measured frequency shifts might come not just from each ping’s transmission from plane to satellite, but also from the ping’s subsequent transmission from the satellite to a ground station that connects the satellites into the Inmarsat network. In other words, Exner may have found the hidden source that seems to be throwing off the frequency graph.
Inmarsat’s analysis is highly ambiguous about whether the satellite-to-ground transmission contributed to the measured frequency shift. But if it did, a ground station located significantly south of the satellite would have resulted in frequency shifts that could account for the measured shifts being too large at the beginning of the graph and too small at the end. And sure enough, Inmarsat’s analysis states that the ground station receiving the transmission was located in Australia.
It’s possible to check the theory more precisely. Public records of Inmarsat ground stations show just one in Australia: in Perth. Using STK, you can precisely chart the satellite’s speed relative to this station, and, using the satellite-to-ground signal frequency (about 3.6 GHz), you can then factor the satellite-to-ground shifts out of the frequency graph. Finally, you can at last calculate the true satellite-to-plane speed values.
The results seem to be nearly perfect. For the first ping, you wind up with a satellite-to-plane speed of about 1 mile per hour—just what you’d expect for a plane stationary or slowly taxiing eleven minutes before takeoff. This finding seems to provide a basic sanity check for interpreting the graph, and led Exner to declare on Twitter, “Doppler code cracked.” He produced a new graph of the frequency shifts, shown below. The gently sloping blue line shows the shifts between the satellite and the ground station in Perth, while the dotted red line shows the newly calculated satellite-to-plane shifts:
to understand the Inmarsat analysis. But that just means that Inmarsat’s analysis, as it has been presented, remains deeply confusing, or perhaps deeply confused. And there are other reasons to believe that Inmarsat’s analysis is not just unclear but mistaken. (Inmarsat stands by its analysis. More on that in a minute.)
Recall that the Marco-Polo math alone doesn’t allow you to tell which direction pings are coming from. So how could Inmarsat claim to distinguish between a northern and southern path at all? The reason is that the satellite itself wasn’t stationary. Because the satellite was moving north-south, it would have been moving faster toward one path than another—specifically, faster toward a southbound track than a northbound one over the last several hours of the flight. This means that the frequency shifts would also differ between a northbound and southbound path, as the graph shows with its two predicted paths.
But this is actually where the graph makes the least sense. The graph only shows different predicted values for the north and south tracks beginning at 19:40 UTC (presumably Inmarsat’s model used actual radar before this). By this time, the satellite was traveling south, and its southward speed would increase for the rest of the flight. The frequency shift plots for northern and southern paths, then, should get steadily further apart for the rest of the flight. Instead, the graph shows them growing closer. Eventually, they even pass each other: by the end of the flight, the graph shows the satellite traveling faster toward a northbound flight path than a southbound one, even though the satellite itself was flying south.
One ping alone is damning. At 19:40 UTC, the satellite was almost motionless, having just reached its northernmost point. The graph shows a difference of about 80 Hz between predicted northbound and southbound paths at this time, which would require the satellite to be moving 33 miles per hour faster toward the southbound path than the northbound one. But the satellite’s overall speed was just 0.07 miles per hour at that time.
Inmarsat claims that it found a difference between a southbound and northbound path based on the satellite’s motion. But a graph of the frequency shifts along those paths should look very different from the one Inmarsat has produced.
Either Inmarsat's analysis doesn't totally make sense, or it's flat-out wrong. [...]
For the last two months, I’ve been trying to get authorities to answer these questions. Malaysia Airlines has not returned multiple requests for comment, nor have officials at the Malaysian Ministry of Transportation. Australia’s Joint Agency Coordination Centre and the UK’s Air Accidents Investigation Branch, which have been heavily involved in the investigation, both declined to comment.
An Inmarsat official told me that to “a high degree of certainty, the proponents of other paths are wrong. The model has been carefully mapped out using all the available data.”
The official cited Inmarsat’s participation in the investigation as preventing it from giving further detail, and did not reply to requests for comments on even basic technical questions about the analysis. Inmarsat has repeatedly claimed that it checked its model against other aircrafts that were flying at the time, and peer-reviewed the model with other industry experts. But Inmarsat won’t say who reviewed it, how closely, or what level of detail they were given.
Until officials provide more information, the claim that Flight 370 went south rests not on the weight of mathematics but on faith in authority. Inmarsat officials and search authorities seem to want it both ways: They release charts, graphics, and statements that give the appearance of being backed by math and science, while refusing to fully explain their methodologies. And over the course of this investigation, those authorities have repeatedly issued confident pronouncements that they’ve later quietly walked back.
The biggest risk to the investigation now is that authorities continue to assume they’ve finally found the area where the plane went down, while failing to explore other possibilities simply because they don’t fit with a mathematical analysis that may not even hold up.
After all, searchers have yet to find any hard evidence—not so much as a shred of debris—to confirm that they’re looking in the right ocean.

The claims of Australian company Georesonance do not hold up because:
* They make nonsensical claims such as detecting copper by "electromagnetic fields" from aerial images. However the copper would be behind the skin of the plane, and under 680m of seawater. Hence impossible to detect. https://www.metabunk.org/threads/du...ves-it-may-have-found-mh370.3558/#post-103545
* The company itself was created in 2013 and has almost no history or internet presence before this story
* They claim to have located a ship, which is still missing - https://www.metabunk.org/threads/du...ves-it-may-have-found-mh370.3558/#post-103382

(34) Claim of MH370 wreckage in Bay of Bengal obligates search; Bangladesh sends frigates

Claim of possible Flight 370 wreckage obligates searchers to look, experts say
By Tom Watkins and Holly Yan, CNN
April 30, 2014 -- Updated 1842 GMT (0242 HKT)
* Bangladesh sends two frigates into the Bay of Bengal to investigate
* "The investigators are going to be hard-pressed to blow this off," says aviation analyst
* More than 600 military members from around the world end their air search
* Crews will now search a larger area of the ocean floor
(CNN) -- Even as they were rejecting as far-fetched an Australian company's assertion that it may have identified the resting place of Malaysia Airlines Flight 370 -- thousands of miles from where investigators have been searching -- experts acknowledged Wednesday that they have little choice but to check it out.
"The investigators are going to be hard-pressed to blow this off," said Mary Schiavo, a former inspector general for the Department of Transportation. "I think, at this point, because of the lack of results where they've been searching for six weeks, they're almost stuck. They have to go look."
The Adelaide-based firm GeoResonance has said that electromagnetic fields captured by airborne multispectral images some 118 miles (190 kilometers) off the coast of Bangladesh in the Bay of Bengal showed evidence of aluminum, titanium, copper and other elements that could have been part of the Boeing 777-200ER, which disappeared from radar on March 8 while en route from Kuala Lumpur, Malaysia, to Beijing.
"The company is not declaring this is MH370, however it should be investigated," GeoResonance said Tuesday in a news release.
GeoResonance Managing Director Pavel Kursa, citing intellectual property concerns, would not explain how the imaging works.
Nevertheless, the company got its wish on Wednesday, when Bangladesh sent two navy frigates into the Bay of Bengal to the location cited by GeoResonance. "As soon as they get there, they will search and verify the information," Commodore Rashed Ali, director of Bangladesh navy intelligence, told CNN in Dhaka.
The chief coordinator of the Joint Agency Coordination Centre, retired Chief Air Marshal Angus Houston, held out little optimism that any such search would prove fruitful. He told Sky News International that the search area in the Indian Ocean had been set based on pings believed to have emanated from one or both of the plane's voice and data recorders. "The advice from the experts is that's probably where the aircraft lost power and, somewhere close to that, it probably entered the water."
CNN aviation expert Miles O'Brien said GeoResonance's claims are not supported by experts. "My blood is boiling," he told CNN's "New Day." "I've talked to the leading experts in satellite imaging capability at NASA, and they know of no technology that is capable of doing this. I am just horrified that a company would use this event to gain attention like this."
