everything to do with the info that we are being spoon-fed from various semi-official sources.
I happen to agree with you that many of the newspaper headlines, journalist choose to
emphasize the more sensational aspects of the story, in order to sell more newspapers.
However, readers must also be diligent to evaluate the statements made by anonymous sources.
If you think an experienced pilot should be disregarded because he is titled a "talking head",
then what title do you ascribe to the opinions of anonymous Websleuths posters have ?
Unfortunately we are unaware whether the opinions stated here,
come from a place of education & experience ... or elsewhere.
In order to counteract this disadvantage, as I understand it, Websleuths
has a policy that a poster should back up their statements with references.
Such a policy aids other posters in evaluating the veracity of the statements made.
the ELT's should have nothing to do with ACARS. Turning off ACARS/SATCOM should not affect the ELT's.
This sounds to me like a very tentative statment ...
Can you please provide a reference that backs up your supposition ?
On the other hand, I DID provide a reference in message #96 here,
where a retired pilot with many years of experience at Malaysia airlines
claimed that in order to function properly, the ELT
required ACARS.
Since I am unaware of your personal background, it would be most helpfull
if you could please provide another reference from an experienced individual,
towards clarifing if there is a problem with the claim made by THIS pilot.
In order for ELT's to transmit, they must be above the waterline ...
IF MH-370 hard-landed on the Indian Ocean and remained intact, one or more of the four ELT's
I have NOT read anyone state that they think that MH370 hard landed on top of the
Indian Ocean intact & remained floating. So I am confused at to why you bring up this
unlikely possibility ??? Everything I have read says that it sank under the water.
ACARS stands for "Aircraft Communications Addressing and Reporting System".
If you suppose that ELT is not using ACARS, then can you please tell me
which communications system, an ELT uses to broadcast the locater frequency ?
Malaysian Airlines subscribed to engine-health monitoring via ACARS, with SATCOM
provided by Inmarsat. This is why Rolls-Royce in Great Britain received two engine
health messages before MH-370 disappeared from transponder radar.
I think you have misunderstood the workings of the Rolls Royce engine health maintenance PLANS.
They offer more than one option. ALL commercial planes have engines monitored automatically through ACARS.
IF & ONLY IF the airlines decides to pay extra for the advanced engine health maintenance plan
THEN Rolls Royce would monitor further ... would that be through SATCOM ???
In message #43 here I provided an MSM reference saying that Malaysian Airlines divulged that they
did NOT pay the required subscription fee for the advanced engine health maintenance plan ...
fail to understand is HOW they get that info ... it IS transmitted to them through the ACARS system.

Aircraft Engine Monitoring: How It Works And How It Could Help Malaysia Air 370 Crash Investigators
[begin excerpt]
the final ACARS transmission indicated that everything was normal with the engines
on MH370 ... the Bloomberg news service cited a source as saying that
MAS opted out of a Boeing service
to collect real-time performance data from jets like the 777-200ER used by MH370
for use in planning maintenance. The source said
MAS now collated such data itself." [end excerpt]
MH370 sent it's very last automatic ACARS data transmission @1:07am MYT (@17:07 UTC).
The next one was scheduled to come in @1:37 but it never came through.
Therefore Rolls Royce has NO data to share after that time.
The transponder had ceased functioning.
In order to disable ACARS, both VHF and SATCOM must be disabled.
Can you please provide a reference for this statement ?
I have NEVER read that SATCOM was disabled !
I personally think ACARS & SATCOM are 2 different systems.
The pilot has access to ACARS ... but please enlighten me if a pilot has access to SATCOM.
My reading has indicated that SATCOM is located in a separate computer on top of the plane.
We have a theory (Inmarsat pings) based upon a never-tried before model that has
somehow evolved to become the "foundation fact" that all other theorists must accept,
or face ridicule and banishment. This is a logical non sequitur, in that some
talking-heads are saying, in effect: "we know that this unproven theory is a fact,
so we do not want to hear about YOUR unproven theories"!
In my opinion, this statement reflects a misunderstanding about
which part
of the Inmarsat data is FACT & which part of the Inmarsat data is THEORY.
One can argue about the theoretical location of the plane because that is questionable,
BUT the fact that the handshakes occurred is a reality.
Excluding location, can you please explain EXACTLY what you think is
theory
about the satellite communicating with an
airborne MH370 at these UTC times below
which were reflected in 2 separate computers (Inmarsat & ground station) ...

This fact means that MH370 was STILL flying at 8am MYT. The only part logical people
can argue about, is the theory about WHERE the plane went down AFTER that time.
Rhyolite has mentioned that Inmarsat theory could be affected by the heat of a fire.
In my personal opinion, heat would alter the location by hundreds of miles,
but not thousands of mile ... however that is debatable.
So in summary, a plane going down at 8am MYT in the Maldives or Andaman Islands
remains a small possibility ... but a plane going down anywhere at 3am MYT
is NOT a possibility given the satellite evidence in existence at 8am MYT.
