Malaysia Airlines Loses Contact With 777 en Route to Beijing
on the news now is something about the 'ping' being sent but having no data because MA had 'not subscribed to the full service'....the articale on Sky news then goes on to talk about ACARS,......which has been mentioned here a lot.
can somebody put this into english please?? does ACARS have a subscription service that is optional??
or is it once again them talking bollox cause they dont know what they are on about??
U.S. officials have an "indication" the missing Malaysia Airlines jetliner may have crashed in the Indian Ocean and is moving the USS Kidd to the area to begin searching.
It's not clear what the indication was, but senior administration officials told ABC News the missing Malaysian flight continued to "ping" a satellite on an hourly basis after it lost contact with radar.
Two U.S. officials tell ABC News the U.S. believes that the shutdown of two communication systems happened separately on Malaysia Airlines Flight 370. One source said this indicates the plane did not come out of the sky because of a catastrophic failure.
The data reporting system, they believe, was shut down at 1:07 a.m. The transponder -- which transmits location and altitude -- shut down at 1:21 a.m.
This indicates it may well have been a deliberate act, ABC News aviation consultant John Nance said.
U.S. investigators told ABC News that the two modes of communication were "systematically shut down."
That means the U.S. team "is convinced that there was manual intervention," a source said, which means it was likely not an accident or catastrophic malfunction that took the plane out of the sky.
"Boeing offers a satellite service that can receive a stream of data during flight on how the aircraft is functioning. Malaysia Airlines didn't subscribe to that service, but the plane still had the capability of connecting with the satellite and was automatically sending pings."

Indeed, despite the reports we posted last night being either ignored or scoffed at on this forum, it would appear that they're authentic. Time for people to smell the coffee here. Someone commandeered this plane for nefarious reasons: that's the most probable line of inquiry at this time. My bet is still on the pilot.
Extending the flight time from when the transponder, etc were disabled would allow the plane to be crashed far away from the last known location, but there is an interesting additional benefit mentioned in the comments on AVHerald that extending the flight time would mean that the FDR & CVR records of the "intervention" would have been over written thereby removing another bit of evidence.

To which I have to say, this was pulled off by someone who understood every nuance of what he was doing. Dropping off radar right when communications were switched over, thus providing a cushion in determining when something was amiss, is another example. An intelligent, practiced aviator was behind this. Did he accomplish what he intended? Possibly...
Two sources said an unidentified aircraft that investigators believe was Flight MH370 was following a route between navigational waypoints - indicating it was being flown by someone with aviation training - when it was last plotted on military radar off the country's northwest coast.
The last plot on the military radar's tracking suggested the plane was flying toward India's Andaman Islands, a chain of isles between the Andaman Sea and the Bay of Bengal, they said.
Waypoints are geographic locations, worked out by calculating longitude and latitude, that help pilots navigate along established air corridors.
Rules out a HA522 scenario.

In the afternoon of Mar 14th 2014 Malaysia's Transport Minister re-iterated, that there was a primary target seen indeed, it may be MH-370 but could be any other aircraft too. It can neither be confirmed nor ruled out that this radar target was MH-370. As result the search areas are being widened into the Indian Ocean beyond Andaman Islands to the west as well as to the east further into the South China Sea. Two oil slicks have been discovered near the position of last contact, one of these oil slicks contained jet fuel, however, it is not clear whether this jet fuel comes from MH-370 or not. Malaysia is sharing data that would normally not be shared with the public in the interest of national security. Media reports that the aircraft transmitted any data beyond the point of last contact are not true.

I believe them. They don't have the slightest clue of what on Earth happened to this plane, other than they lost contact with it in the middle of the Gulf of Thailand.
I'm starting to think that there was no primary radar coverage at the point of loss of contact (and if this was foul play perhaps the perpetrator knew it), but yes in other places closer to land, so they have tons of primary radar data but no way to know which one of the many blips, if any, is MH.
On a different note, the CVR of the 777 records the last 2 hours, the FDR records many, many hours (enough to keep several full flights in it).
But if there is foul play here and the person involved knew enough to make all this, he could perfectly kill the CVR and FDR at the same time that he did so with the transponder and ACARS.
Re the oil sleek containing jet fuel:
a) Would not the jet fuel have already evaporated after so many days? Oh, well, they never said when thy found it. Maybe it was days ago.
b) A smart perpetrator dumping fuel at low altitude to leave a misleading sleek?

Question - pilots or someone in the cockpit can turn off transponder and automated transmitting systems (except apparently the engine maintenance system unless that was an oversight). Could a rouge pilot/person in cockpit also turn off pressurization system to disable passengers (which may explain no cell phone contacts) and others or is this system automatic except for temperature?

Enough with the cell phones, they will not work at altitude. And I doubt there are any towers out there even if they could.
Also it would take someone with some pretty good knowledge of the systems to start pulling the right breakers to shut down not only both transponders, but the complete ACARS system.
AFAIK, you only need to shut down the SBD transceiver to silence ACARS, and that would be circuit breaker P11-1, Position C9.
And that's from someone with only pretty good knowledge of the internet.
Agreed. But understand that saying the aircraft transmitted no data does not mean that the communications link was not still enabled. That is to say there might have been a satellite or radio link still connected (up to even just the the data link layer of the OSI model - http://en.wikipedia.org/wiki/OSI_model) but with the transmitting system disabled. Satellites or other infrastructure may still have some record of those data link connections? Enough just to say the aircraft was still "on", not crashed (yet)...
