I understand all of this actually. I live with a pilot ;) learned recently that you need 45 minutes worth of fuel if you are landing after dark, only 20 minutes if you land during daylight. Or at least that was the company policy for his last job. Not sure what his current job requires, he's flying medical transfers from up north now, so I'm guessing their protocols are different from his last company that did mainly charters. Can't wait for him to get on with Jazz or Encore because I have dibs on the buddy pass!
not true.

the 20 minute day-VFR fuel reserve is for helicopter. day-VFR fuel reserve for fixed-wing aeroplane is 30 minutes at cruise speed. fuel reserve for night-VFR is yes 45 minutes at cruise.

however, Malaysian Airlines, and well all airlines, file IFR. fuel required to destination plus a missed-approach at said destination airport, fuel to flight-planned alternate, plus fuel for an additional 30 minutes.

within Canada YVR's usual alternates are YXX and occasionally YYJ. internationally speaking it's generally SEA. but strange things happen. just last week an Air Canada 777 SYD-YVR diverted to LAX because of crew-duty time issues. i guess it was cheaper for the crew to time-out in LA than in Sydney or Honolulu.

It seems that all of the investigators and governments involved have come to the conclusion that one of the pilots deliberately diverted flight 370. Malaysia has searched both pilot's homes and removed material from the co-pilot's home. Apparently, all of the passengers are going to be investigated also.

Missing jet: Not a hijacking but 'deliberate' action, PM says
By Faith Karimi and Barbara Starr CNN
updated 10:58 AM EDT, Sat March 15, 2014
(CNN) -- The Malaysian Prime Minister stopped short of calling the disappearance of Flight 370 a hijacking, but he said Saturday that the jet veered off course, likely due to deliberate action taken by someone aboard.

With that revelation on Day 8, the search for the missing Malaysian Airlines plane refocused on the crew and passengers and widened to a larger swath of geography.

The passenger jetliner disappeared March 8, en route from the Malaysian capital Kuala Lumpur to Beijing, China.

"Evidence is consistent with someone acting deliberately from inside the plane," Prime Minister Najib Razak said, officially confirming the plane's disappearance was not caused by an accident.

"Despite media reports that the plane was hijacked, we are investigating all major possibilities on what caused MH370 to deviate," he said.

Military radar showed the jetliner flew in a westerly direction back over the peninsula before turning northwest toward the Bay of Bengal or southwest into the Indian Ocean, Najib said.

"Up until the point at which it left military primary radar coverage, these movements are consistent with deliberate action by someone on the plane," he said.

Investigators, he said, have confirmed by looking at the raw satellite data that the plane in question was the Malaysia Airlines jet.

The same conclusion was reached by the U.S. Federal Aviation Administration, the U.S. National Transportation Safety Board, the British Air Accidents Investigation Branch and the Malaysian authorities, all of whom were working separately with the same data, he said.

Pilot's home searched

Shortly after Najib spoke with reporters, a source close to the investigation told CNN that Malaysian police had searched the home of pilot Zaharie Ahmad Shah, 53. Shah lives in a gated community in Shah Alam, outside Kuala Lumpur.

Police made no comment about their activities at the home of co-pilot, Fariq Ab Hamid, 27. Two vans exited the home carrying small bags, similar to shopping bags, but it was unclear whether the bags were taken from the home. ...

Nothing terrifies more than the unknown. It wouldn't surprise that there will be enough found during background checks to implicate one or more of the larger terrorist networks, but no trace will be found of the plane or passengers. Perhaps the black boxes were disabled and the plane was put down softly on deep water and let sink so there wouldn't be a debris field to find.In a case like this, the mystery will have a more profound effect on the public than knowing what happened.

Malaysia Airlines Flight MH370's communications were switched off, PM says
The Associated Press Posted: Mar 15, 2014 6:39 AM ET| Last Updated: Mar 15, 2014 4:55 PM ET

The missing Malaysian jetliner was deliberately diverted and continued flying for more than six hours after severing contact with the ground, meaning it could have gone as far northwest as Kazakhstan or into the Indian Ocean's southern reaches, Malaysia's leader said Saturday.

Prime Minister Najib Razak's statement confirmed days of mounting speculation that the disappearance of Malaysia Airlines Flight 370 to Beijing more than a week ago was not accidental. It also refocused the investigation into the flight's crew and passengers, and underlined the complicated task for searchers who already have been scouring vast areas of ocean.

"Clearly the search for MH370 has entered a new phase," Najib said at a televised news conference.

Najib stressed that investigators were looking into all possibilities as to why the Boeing 777 deviated so drastically from its original flight path, saying authorities could not confirm whether it was a hijacking. Earlier Saturday, a Malaysian official said the plane had been hijacked, though he added that no motive had been established and no demands had been made known.

"In view of this latest development, the Malaysian authorities have refocused their investigation into the crew and passengers on board," Najib told reporters, reading from a written statement but not taking any questions.

Pilots' homes searched

Police on Saturday went to the Kuala Lumpur homes of both the pilot and co-pilot of the missing plane, according to a guard and several local reporters. Authorities have said they will investigate the pilots as part of their probe, but have released no information about how they are progressing.

Experts have previously said that whoever disabled the plane's communication systems and then flew the jet must have had a high degree of technical knowledge and flying experience. One possibility they have raised was that one of the pilots wanted to commit suicide.

The plane was carrying 239 people when it departed for an overnight flight from Kuala Lumpur to Beijing at 12:40 a.m. on March 8. Its communications with civilian air controllers were severed at about 1:20 a.m., and the jet went missing — heralding one of the most puzzling mysteries in modern aviation history.

China, where the bulk of the passengers were from, expressed irritation over what it described as Malaysia's foot-dragging in releasing information about the search.

Investigators now have a high degree of certainty that one of the plane's communications systems — the Aircraft Communications Addressing and Reporting System — was disabled before the aircraft reached the east coast of Malaysia, Najib said. Shortly afterward, someone on board switched off the aircraft's transponder, which communicates with civilian air traffic controllers.

Najib confirmed that Malaysian air force defense radar picked up traces of the plane turning back westward, crossing over Peninsular Malaysia into the northern stretches of the Strait of Malacca. Authorities previously had said this radar data could not be verified.

"These movements are consistent with deliberate action by someone on the plane," Najib said

Although the aircraft was flying virtually blind to air traffic controllers at this point, onboard equipment continued to send "pings" to satellites.

The prime minister said the last confirmed signal between the plane and a satellite came at 8:11 a.m. — 7 hours and 31 minutes after takeoff. This was more than five hours later than the previous time given by Malaysian authorities as the possible last contact.

Airline officials have said the plane had enough fuel to fly for up to about eight hours.

"The investigations team is making further calculations which will indicate how far the aircraft may have flown after this last point of contact," Najib said.

He said authorities had determined that the plane's last communication with a satellite was in one of two possible arcs, or "corridors" — a northern one from northern Thailand through to the border of the Central Asian countries Kazakhstan and Turkmenistan, and a southern one from Indonesia to the southern Indian Ocean.

The northern route might theoretically have taken the plane through China, India, Pakistan, Afghanistan — which hosts U.S. military bases — and Central Asia, and it is unclear how it might have gone undetected. The region is also home to extremist Islamist groups, unstable governments and remote, sparsely populated areas.

Search extends to southern Indian Ocean

Flying south would have put the plane over the Indian Ocean, with an average depth of 3,890 metres (12,762 feet) and thousands of kilometres (miles) from the nearest land mass.

Britain-based aviation security consultant Chris Yates thought it was highly unlikely the plane would have taken the northern route across land in Asia.

"In theory, any country that sees a strange blip is going to get fighter planes up to have a look," he said. "And if those fighter planes can't make head or tail of what it is, they will shoot it down."

Najib said search efforts in the South China Sea, where the plane first lost contact, had ended.

China says no timely sharing of information

Two-thirds of the plane's 227 passengers were Chinese, and China's government has been under pressure to give relatives firm news of the aircraft's fate.

In a stinging commentary on Saturday, the Chinese government's Xinhua News Agency said the Malaysian information was "painfully belated," resulting in wasted efforts and straining the nerves of relatives.

"Given today's technology, the delay smacks of either dereliction of duty or reluctance to share information in a full and timely manner," Xinhua said. "That would be intolerable."

Najib said he understood the need for families to receive information, but that his government wanted to release only fully corroborated reports. He said his country has been sharing information with international investigators, even when it meant placing "national security concerns" second to the search. U.S., British and Malaysian air safety investigators have been on the ground in Malaysia to assist with the investigation.

In the Chinese capital, relatives of passengers who have anxiously awaited news at a hotel near Beijing's airport said they felt deceived at not being told earlier about the plane's last signal. "We are going through a roller coaster, and we feel helpless and powerless," said a woman, who declined to give her name.

At least one of the relatives saw a glimmer of hope in word that the plane's disappearance was a deliberate act, rather than a crash. "It's very good," said a woman, who gave only her surname, Wen.

Malaysian police have already said they are looking at the psychological state, family life and connections of pilot Zaharie Ahmad Shah, 53, and co-pilot Fariq Abdul Hamid, 27. Both have been described as respectable, community-minded men.

Zaharie joined Malaysia Airlines in 1981 and had more than 18,000 hours of flying experience. His Facebook page showed an aviation enthusiast who flew remote-controlled aircraft, posting pictures of his collection, which included a lightweight twin-engine helicopter and an amphibious aircraft.

Fourteen countries are involved in the search for the plane, using 43 ships and 58 aircraft.Fariq was contemplating marriage after having just graduated to the cockpit of a Boeing 777. He has drawn scrutiny after the revelation that in 2011, he and another pilot invited two women aboard their aircraft to sit in the cockpit for a flight from Phuket, Thailand, to Kuala Lumpur.

A U.S. P-8A Poseidon, the most advanced long-range anti-submarine and anti-surface warfare aircraft in the world, was to arrive over the weekend and sweep parts of the Indian Ocean, the U.S. Defence Department said in a statement.

What I don't understand, is why a plane like a 777 gives the pilots the ability to shut off all communications, transponders, ect.
Why do they need this ability?
The X-ponder and ACARs [aircraft communication address & reporting] both have circuit breakers to disable the system if they short out.
The info we have is they both were de-activated within minutes of each other, something a normal pilot would not do unless in electrical distress of those systems.
Boeing also has a separate radio that sends hourly data to a satellite relay back to Boeing, this signal was still pinging 7 hours after take off.

And when did they lose communication? 4 or 5 hours?
How far could it have gone in the extra hours?
Just over 2800 miles, assuming standard cruising speed of 905kph/562mph

The black boxes have a transponder that pings. Only problem is it's a very narrow bandwidth and it doesn't ping over long distances. They are not powered by a battery only when it's connected to the planes electrical system once the planes electrical systen is exhausted or non functioning a small radioactive isotope takes over the pinging. It can apparently last over a month.

When the Air france plane went down 2 + years ago they finally found it using side scan radar/sonar long after the pinging transponders had timed out.
The FDR blackbox has an UBL [underwater beacon locator], not a transponder, which sends a ping whenever it is immersed in water. Unfortunately the signal has limited range and lifespan. That's one of the reason the Air France jet was not found by tracing the pinger.

Caught on CCTV: Pilots of doomed Malaysian Airlines flight walk through security for the final time before take-off

Footage captures Captain Zaharie Ahmad Shah being frisked by security
He is followed by co-pilot Fariq Hamid who was also searched
Shah 'fanatical' supporter of the country's opposition leader Anwar Ibrahim
Pilot's wife and three children moved out of family home the day before plane went missing

By Tara Brady

PUBLISHED: 18:04 GMT, 16 March 2014 | UPDATED: 18:41 GMT, 16 March 2014

This is the moment the pilots of the doomed Malaysian Airlines flight walked through security for the
final time before take-off.
CCTV footage captures Captain Zaharie Ahmad Shah, pilot of the Boeing 777 flight, being frisked while walking through security at Kuala Lumpar International Airport.
He is then joined by co-pilot Fariq Hamid who is also searched before the pair walk onto the plane.
Officials revealed today that it is possible the aircraft could have landed and transmitted a satellite signal from the ground.
Shah, a father-of-three, was said to be a 'fanatical' supporter of the country's opposition leader Anwar Ibrahim - jailed for homosexuality just hours before the jet disappeared.
It has also been revealed that the pilot's wife and three children moved out of the family home the
day before the plane went missing.
It comes as FBI investigators say the disappearance of MH370 may have been ‘an act of piracy’ and the possibility that hundreds of passengers are being held at an unknown location has not been ruled out.
Officials revealed today that it is possible the aircraft could have landed and transmitted a satellite signal from the ground.
f the plane was intact and had enough electrical power in reserve, it would be able to send out a radar 'ping'.
The final words from the missing Malaysian jetliner's cockpit have given no indication anything was wrong even though one of the plane's communications systems had already been disabled, officials have said adding to suspicions that one or both of the pilots were involved in the disappearance.
As authorities examined a flight simulator that was confiscated from the home of one of the pilots and
dug through the background of all 239 people on board and the ground crew that serviced the plane,
they also were grappling with the enormity of the search ahead of them, warning they needed more data to narrow down the hunt for the aircraft.
The Malaysia Airlines Boeing 777 took off from Kuala Lumpur at around 12.40am on March 8, headed to Beijing.
On Saturday, Malaysia's government confirmed that the plane was deliberately diverted and may
have flown as far north as Central Asia, or south into the vast reaches of the Indian Ocean.
Authorities have said someone on board the plane first disabled one of its communications systems -
the Aircraft and Communications Addressing and Reporting System, or ACARS - at 1.07am.
Around 14 minutes later, the transponder, which identifies the plane to commercial radar systems, was also shut down.
The fact that they went dark separately is strong evidence that the plane's disappearance was
deliberate.
Today, Malaysian Defense Minister Hishammuddin Hussein said at a news conference that the final, reassuring words from the cockpit - 'All right, good night' - were spoken to air traffic controllers after the ACARS system was shut down.
Whoever spoke did not mention any trouble on board, seemingly misleading ground control. . . .


There are also Asian sites that are now reporting:

Now Malaysia has the problem of figuring out where the plane is if the pilot has stolen it or (more likely) where in the Indian Ocean the pilot committed murder/suicide by ditching into the ocean.

If the plane had been landed with 238 hostages, the world would already know where they are. Probably 80% of the passengers had cellphones and they would have been phoning as soon as the wheels hit the ground - especially once they realized that they weren't landing in Beijing.

It's very likely that the Pilot got the Co-Pilot out of the cockpit on one pretext or another (the way the Turkish Airliner was hijacked) and then locked the cockpit door. A land over flight would have flown over countries that have cell phone reception and no cell phone calls were made. That means an ocean route. The middle of the Indian Ocean has no cell phone reception.

That's interesting info and I have been following this one closely. The only problem I have with this news is on the Transponder issue. I watched an interview of a Boeing 777 pilot and he stated it is not simply a single switch to turn off the Transponder and Communication Systems. There are 13 redundancy systems backing up both the Transponder and Communication Systems. Boeing built them specifically with this hijacking scenario in mind. He said it was not a simple case of a single switch being turned off either by design or accidentally.

There must have been collusion by both pilots to make this happen.

Actually, that built in redundancy is why we have any idea of how long and where the plane traveled after the Pilot turned the communications systems off. We know the plane traveled about 2800 miles during the 5 hours after the transponder was turned off - but the ACAR from the engines was still transmitting data. It would be nice if the engine data system gave GPS data - but it doesn't. So, Malaysia has a 3000 mile circle from where the plane was when it turned off the transponders that they must search.

There is a radar contact after the plane crossed the Malaysian Peninsula into the Indian Ocean that would make an Ocean route more likely than a land route. But that's a lot of Ocean. Surface Anti-Submarine Warfare ships won't be able to search the deeper parts of the Indian Ocean. They are going to have to ask for Submarines and that's going to risk some technology that we really never wanted the world to know about. If they had a few hundred square miles to search, the search would be done quickly enough that the risk could be managed, but, they have several million square miles to search.

There is a satellite system that may have a record of the flight, but, it's not designed to follow commercial aviation traffic and the data would have to be collected and given to a large team to painstakingly examine.

All of the people that were cheering NSA whistleblower Snowden are going to find out that the people that control the technology are unwilling to have that technologies capabilities closely examined by people who aren't tested and true.

People are confusing the ACARS with a separate Boeing satellite link.
The ACARS went unserviceable early in the flight and did not send info after that, [the Wall Street Journal published a report about Rolls-Royce recieving data, but RR denied it].
The Boeing satellite link received weak signals for several hours after the jet disappeared from radar.

The latest info now states that we may never know what happened if investigators rely on the black box. The black box only keeps data for 2 hours then overrides the previous data

All this was carefully planned to the last detail. It's also very possible (likely) that a shoe-bmb was used to gain access to the cockpit or one of the pilots (I am going with the co-pilot if either them were involved) left the door open.

Various sources are reporting that the military radar shows extreme altitude changes. UP to 45,000 ft (recommended service ceiling is 38,000 ft) and then Down to 23,000 ft.

Since the passenger cabin pressurization is designed for a maximum altitude of 38,000 ft, the passengers were likely dead when the aircraft went down to 23,000 ft

Wikipedia has collated the information on MH 370 http://en.wikipedia.org/wiki/Malaysia_Airlines_Flight_370

Australia has added resources to the search, including a look back at the data stored by JORN - the Australian defense Radar system. http://en.wikipedia.org/wiki/Jindalee_Operational_Radar_Network

If they are extremely lucky, JORN will have a record of the plane at it's SouthEast possible location at 8:10AM which is when the ACARS/Inmarsat system failed to "handshake" with the plane.

If JORN saw the plane, the search area will be reduced from millions of square miles to a couple of hundred square miles.

That would make complete sense. Once landed (presuming the plane landed) it would be a huge undertaking to kill all the passengers. I mean, the Nazis had trains that pulled into the gas chambers as well as group showers.

On another note. I wouldnt trust wiki. Wiki info is entered by simple folk like you and me and anyone can write whatever they want and quote any resource.

People are super serious about Wiki though, it's a hobby for people and they have a huge hard on about making anything right. If you go to any article that has any notice and try to edit it, someone will be there to fix it in 10 minutes. It's crazy how much better Wikipedia has gotten. While I wouldn't rely on it as your sole source or anything, it's a decent compiling of info, especially about major events - for the most part.




How do the pilots survive?
The Pilot's compartment has it's own separate Oxygen and controls if the Oxygen masks drop in the passenger compartment. However, a google for when the oxygen masks are deployed on the Boeing 777 came up with this:

Malaysian Airlines MH370: Could Viral Stanford Student’s Theory Solve the Mystery?
By Athena Yenko | March 14, 2014 4:24 PM EST

Andrew Aude, 20, undergraduate computer science student at Stanford University came out of his own theory surrounding the unprecedented mystery of the missing Malaysia Airlines MH370.

He posted his theory through his Tumbler account on March 10 and although it had yet to be verified by aviation experts, the post had since became viral online.

Mr Aude based his theory on a 2013 Federal Aviation Authority (FAA) Airworthiness Directive for the Boeing 777 saying that 777 had one flaw - a "cracking in the fuselage skin underneath the satellite communication (satcom) antenna adapter" was spotted on 777.

With this as his basis, Mr Aude wrote that the missing MH370 might have experienced the same problem which leads to one, failure of satcom and two, a slow decompression which resulted to MH370's pilots disoriented and passengers unconscious.

"If the decompression was slow enough, it's possible the pilots did not realise to put on oxygen masks until it was too late," he wrote.

Mr Aude also wrote that Boeing 777 does not deploy oxygen masks until the cabin altitude reaches 13,500 feet.

"777 Passenger Oxygen masks do not deploy until cabin altitude reaches 13,500. Passengers were likely already unconscious by then, if it was a slow decompression. Also remember that this flight was a red-eye, most passengers would be trying to sleep, masking alarming effects of oxygen deprivation. No confirmed debris has been found in the search area, consistent with the plane having flown for hours after it lost radar contact," he wrote.

According to his opinion, the autopilot function of the MH370 might have lead the plane to travel along its plan route and altitude before plunging into the East China Sea, the Sea of Japan or the Pacific Ocean - miles from the South China Sea where rescue efforts have been concentrated.

He therefore concluded that "this was likely not an explosive decompression or inflight disintegration".

Mr Aude wrote his post after he discovered the FAA's Airworthiness Directive on PPRUNE, forums (Professional Pilots Rumour Network, an aviation website for airline pilots and aviation buffs).

"In the same forum, I discovered how some of the 777's radar systems depend on satcom and GPS. I considered these facts alongside the mobile phones ringing and the mumbling pilots, and I had come up with the proposed explanation," he said.
It would mean that even the pilots were oxygen deprived and the 180 degree course change was the attempt by a semi-conscious pilot to return to the airport

i've been above 13,500 feet before, and yes i was suffering mild altitude sickness - but i was still climbing (on foot) so i highly doubt that either passengers or pilots would be suffering from disorientation

Yes, but they were at 45,000 ft for 45 minutes according to one source. Then the plane lost altitude very rapidly down to 23,000 ft according to the same source. If the person flying the plane was the only person in the cockpit, he had 45 minutes of Oxygen and could prevent Oxygen being delivered to the remainder of the plane. Or according to the Viral Blog, the plane may have lost the communications mast which took out all communications except for the system that handshakes with the satellite every hour. Apparently a 777 lost that communications mast and lost cabin air pressure, but the crew got the plane down to 10,000 ft quickly enough. So it could be a failure of the plane or it could be a deliberate act.
