My answer was to this comment, it wasn't about the data specifically.

We are definitely only being given half of the information available if even that

So if they indeed got a third sat, then they will not tell you anything because they are on it now and looking in a confined area.
And they don't want the perpetrators to know that they are closing in.

Closing in?

The data is over a week old now I'm sure they have long moved on.

So is the Rolls Royce engine data transmitted via ACARS?

Well how come we have some data from the engines then?
If I recall correctly, the data is stored by a third party anyway whether purchased or not and Rolls Royce can access it and not the customer unless they pay for it.
So again my question is why do we only have data for the first half of the flight?
Surely rpms etc come into play during descent and landing?

The system relaying the engine data was turned off , so no more engine data was going to RR after that.

ACARS is the acronym for Aircraft Communications Addressing and Reporting System. It’s an automated communication system used by commercial planes to transmit and receive messages from ground facilities (airline, maintenance department, aircraft or system manufacturer, etc). Therefore, along with the general information about the flight (callsign, speed, altitude, position, etc), these messages may contain what we can consider systems health checks.

ACARS is a service: airlines have to pay for it. According to the information available to date, it looks like Malaysia Airlines subscribed only to engine health monitoring that enabled MH370 to send data to Rolls Royce. The ACARS system aboard MH370 was switched off some minutes before the transponder.
ACARS rely on VHF frequencies (indeed, you can track planes and decode messages with a simple radio receiver tuned on the proper ACARS frequencies and a software running on your computer) or SATCOM (SATellite COMmunication). Although this is still debated, according to several pilots the ACARS transmissions can be switched off by the pilot from inside the cockpit, by disabling the use of VHF and SATCOM channels. This means that the system is not completely switched off, but it can’t transmit to the receiving stations.

SATCOM is a radio system that uses a constellation of satellites used to trasmit voice, data or both. As said, ACARS can make use of SATCOM to transmit its data to ground stations. Dealing with ACARS, the SATCOM system used by MH370 was linked to the INMARSAT network. Inmarsat is a British satellite telecommunications company, which offers global, mobile services through a constellation of three geostationary satellites. The system relies on “pings”.

PING A Ping is a quite common term for IT Networking. It refers to a utility used to test the reachability of a host on an IP network and measure the round-trip time (RTT) of the packets even if it is more frequently associated to the data messages themselves, or “pings”. Similarly to what happens on a Local Area Network, satellites send pings (once a hour) to their receiving peers that respond to it thus signaling their network presence.
Hence, these pings are no more than simple probes used to check the reachability of SATCOM systems aboard the planes.

Based on details recently disclosed, the last response to a satellite ping, was sent by the SATCOM aboard MH370 at 08.11AM Malaysia time, some 7 hours past the loss of contact with the Boeing 777. From the analysis of the time between request and responce it is possible to work out the distance of the plane which is a circumference of certain radius from the satellite based on which, two possible routes were drawn by the investigators. The question is why the hijacker(s) did not prevent the plane from responding to pings: most probably, being a networking detail, not even pilots know that their system/antenna respond “I am here” even if the SATCOM is not being used by any onboard systems (i.e. ACARS).

theaviationist.com...

This article doesn't go into the possibility that the plane could have also pinged when on the ground and not have continued for the whole 7 hours.

What happened with the possible wreckage that was sighted on Tomnod in the Malacca Strait? The Greek tanker Elka Athina was supposed to cruise by there and check it out. I just checked it's position and it has passed by the area and is now out by Banda Aceh.

I don't think they moved on unless they abandoned this plane,
because there are not so many places where you can land this plane.

So the perpetrators rely on the /we are a needle in a haystack/
And a million to 1 this, as the only option to make them fail is
a very sure bet to make for them

Here was the optional performance system that I recalled read about that I mentioned early. It is Boeing. My understanding is the airline was sending data to Rolls-Royce via ACARS, assuming that system is working.

In addition to standard ACARS messages, airlines can install a system sold by Boeing called Airplane Health Management which provides real-time troubleshooting and allows Boeing to monitor the flight as well as the airline, according to its brochure.

This optional system was not installed on the missing Malaysia Airlines jet, people familiar with the matter said.

This operation if possible can only be done in complete secrecy if you have much money and constructed this strip some years ago and hidden it somehow, so there are many odds, who has the motive to do this?

I'll tell you who might. Saudi Arabia's Prince Bandar bin Sultan. And this could possibly be a Syrian/Russian connection as well. Coincidentally, (or not) the Sochi Olympics ends today and the Crimea's referendum begins. If this plane is to be used for battle, it won't be soon. More of a 'proxy" as per the normal ways of war these days. Also 'coincidentally' a Russian 'mouthpiece' Kiselev threatened to turn USA to radioactive dust in another thread.

The plane could be sitting in a hangar in Qatar. It's right along the flight path next to Pakistan.

To me this applies here. So the 777 is in new mexico?
Hope they find it.

The US is now driving the narrative.

According to a twitter user

Saw this on twitter, turns out to be false alarm Foxie News ‏@FoxieNews 3h Greek cargo ships were not told there's suitcases in Malacca Strait. That was a Mis-Translation. They were told to "watch for" items

www.freerepublic.com...

I don't do twitter myself so I don't know how accurate this is, it's possible the media just picked up on this and turned it into a story.

100 posts must do it, if not then never.
nighty night

I wish we knew what cargo was on the plane, if anything other than standard luggage.

If it has landed, then how easy would it be for the plane to fly again now? With everybody on high alert and looking for the plane, surely steps must have been taken to ensure any future 'pings' attributed to it are received in real time. Is this possible or does it take time retrieve this data?

I'm thinking that if it is possible to receive these 'pings' in real time, this could possibly rule out the plane being on the move again or used in an attack, at least in the near future.

I appreciate the information roadgravel
I don't recall from earlier in the thread...but/so, do you know if one of the maps presented has shown 'where' the arcs would have been for each 'ping'?
Thanks again.

While I understand your point, can you explain me a bit more the link between MH370 disappearance and the business friendly environnment remarks by IMF representative? Especially that you are speaking about the actual situation in Ukraine. Thanks

The scenario running in my head is the hijackers, be it the pilots or whoever, will have links to a terrorist organisation which will be comprised of a minority group in a SEA country/region that has not yet fully embraced neorationalism and would like to keep its resources to itself. This will allow the US & friends to basically commence an SEA 'War on Terror'.

This is the Asian Century. It has become a very profitable region given austerity in Europe and sad US economics. Not all countries are as friendly to western corps as western corps would like. It is also a very tumultuous region with some heavy-hitting terrorist groups operating within the region so western corps don't feel as 'relaxed and comfortable' as they'd like. Plus bribery and corruption is a way of life in some of these countries. How can this be changed to suit the interest of corporations?

Wait and see.

The added benefit is it forces countries in the region who are vaccilating between China/Russia & the US/West to make their choice under immense pressure. Malaysia, for example, likes to play both sides but sides with neither. Geopolitically, it has China breathing down its neck, and its China-friendly attitude reflects this, and it has worked hand-in-hand with the US on counter-terrorism measures (and is the only country in SEA with no terror groups based in it) so has a friendly relationship there, too. Maybe it now needs to choose as do many of the other countries Malaysia approached in the region to assist in the search for the plane.

The TPP is due to be signed soon. I'd like to know the bearing it will have on SEA countries. Watch the stock market. That might tell a story.

Hope this makes sense, there are lots of distractions here.

They are here. I think one is also in the post a page or two back I made about the sat system pings. (the linked article)

reply to post by WanDash


They must have calculated arcs from the earlier pings, which means they must have been able to see where the plane was heading. They haven't released this, you've got to wonder why.

My comment on the use of war in the name of peace.

reply to post by roadgravel

Thanks - I'll go look for them.
On the link you posted a page or two back, it only gives a 'map' showing where (red-lined arc) the plane should have been at the last ping.

First let me state that I have been a member of ATS since 2007 but I've been kinda busy fighting ALL and AML and a host of other complications so I can't remember my screen name much less my password. So I'm basically starting from scratch. I have followed the media and this thread actually reading every post and that's a lot of pages. Anyhow, what I find amazing is the fact that people in general do not read an entire post before they start flying off the handle and incorrectly read what is before them. Be that as it may, I get a chuckle over it. I'm not going to drone on but I'll make a few examples:

1) Incorrectly identifying the pilot as the one who had women in the cockpit.

2) The big controversy regarding the photos of the Iranian passengers, They placed one photo over the other or something to that effect. Do you really think they're that stupid?

3) I really like the line of thought of someone going to all this effort to steal the plane for nefarious reasons, the expense to pull this off would probably require more funds than just buying an airplane through a third party.

I think we can all agree on one thing and that is Malaysia has been mucking this up to the extreme and now it's time for someone else to take over the investigation. Maybe a group of aeronautical professionals from several nations. Maybe we could use this to start to work together and solve our differences so we can evolve and provide for the futures of our children.

Now I know I went off base from what I was intending to say but I guess when you've been tested as I have you learn to look at things differently. If I offended anyone I apologize that was not the intention, I want what everyone else here wants and that is that they be found safe and sound.
