Position information based on the last received satellite pings has been released.

It seem obvious that if Search and Rescue have position information from theses pings they will have the same information from older pings. From this info they should give a pretty good idea of which direction the aircraft headed.

Why they haven't released the data on the other pings?

Backseat Dane,


I'm sorry if this has been touched upon before, but a search in this thread for "fake flight plan " doesn't return any hits. So:

Could whoever piloted MH370 have filed a "fake" IFR flight plan for "Whatever flight XXX/Private XXX" in advance and then, when the aircraft had been disappeared over the ocean in an area without ATC and radar coverage, simply present himself as "Whatever flight XXX/Private XXX" in accordance with the filed flight plan to ATC when entering controlled airspace, set the ACs transponder to the designated squawk and then all of a sudden be a legit flight being able to travel in controlled airspace without anyone including military types noticing (for the time being at least)?

Or would ATC know in advance that "Whatever flight XXX/Private XXX" had in fact never taken off from it's filed origin and therefore flag it as trouble? Does - or rather must - the ATC handing the aircraft off into uncontrolled airspace advise the ATC in the other end that "Whatever flight XXX/Private XXX" is approaching in accordance with filed flight plan?

(With a Mode S XPDR I guess you really can't unless ATC doesn't couple the transponders ID with the ICAO database or doesn't notice the discrepancy, but can the pilot of a 777 toggle the transponders mode and run in ie mode A/C?)

((Asking because I'm trying to weed out a conspiracy that's pretty much off the top))
My thoughts also! Especially for an onward flight!

Re my post 4508


Just a thought.
I spent several years building my own aircraft, and although I am pretty competent with electronics, I am by no means an expert.
However I bought an off the shelf mode S transponder, set the hex code myself, installed it then test flew the aircraft. All done with no airframe or avionics experience, as is the case with a lot of home builders out there.
If you were able to smuggle a mode S transponder aboard that T7 I suspect it would be relatively easy for an electronically savvy guy to hook it up and set what ever hex code he desired thereby cloning another aircraft.
I am sure a licensed avionics engineer will shoot me down if I am way off the mark here.
But it may just explain why this guy appears to have been able to fly his aircraft wherever he wanted.

TFOR 2:

I have been "lost" when X controller forgets to hand me off and eventually I fly out of radio range. After some screwing around I find the freq for Y controller and they either want to know what took me so long or who the hell I am :rolleyes:

So........if you wanted to vanish, a freq change is a good place to do it ;)

BTW - For *some* routes, there are sections that have no comms at certain altitudes. New Orleans to Tampa has one such area at 12,000 and below that is about 100 miles long. I do not believe this route is one of these.

A few hours ago in post #4761 I posted a link to an extremely lucid post in which a gentleman/woman with a clear mind, no apparent agenda, and enough intelligence to know what s/he did and did not know, went to a lot of trouble to write a very long summary of much of what has been covered here, over and over again over hundreds of pages.

When I looked to see if the post had survived moderation, it was still there. But no one had mentioned it in subsequent posts, either to say 'yeah, that guy sure did a useful summary' or the contrary.

Being basically grumpy, I conclude that the bulk of the chatter here is coming from people who just want to see their opinions in writing, and/or have no interest in actually reading what others have posted.

That's my opinion; I've read this thread from page one and have made two other contributions: very early, I researched and posted a link to the Federal Register entry in which the FAA was announcing the AD regarding satcom antenna/skin crack, then the link to that summary.

Interesting to see the guy who put the fake FR 24 video on youtube dahboo7 had all his videos removed and was almost arrested, he subsequently set up a new Chanel dahboo77 and put all the videos back, some people live on the edge.
I don't think MAS 370 is meant to be found we may never know.

The trick is for the captain to shut down some comms just before the collision have the collision then sign off the current controller with a laconic americanism then put the SSR/ADS to standby. Obviously learned the stiff upper lip from the English school :cool:

The fix ELT on the 777 can be set off manually in the flight deck or by impact (G-switch)
If someone deliberately hijacked the aircraft they wouldn't want the ELT to activate, so wouldn't use a flight deck switch, and why have such a switch anyway, if you need the ELT you need the ELT, I guess the only reason would be in the case of an accidental activation - heavy landing ? (!!)

If the aircraft has landed deliberately on some secret airstrip, highly unlikely I guess, then it woudn't activate and the same reason as above would apply.

Maybe ? one could land on the ocean, as per the Hudson ditching, softly enough to not activate it, tho' I doubt it, so I guess the only answer is that it has deliberately not been switched on, or activated on contact with the ocean then promptly sank and was swamped. The water activated ones mentioned already are intended for use in liferafts by survivors, I doubt that they too could continue working X-fathoms down.

So - I don't think lack of an ELT signal is too big a mystery ? i.e. it's drowned, or it's deliberately repressed.

Just from the perspective of technical feasibility, with no real theory (new or proposed) resulting:

a) pilot (or someone) pre-programs left-turn VAMPI before IGARI is reached. This is before 1:07 and so appears as an ACARS event

If the pilot or the F/O had pre-programmed VAMPI after IGARI, then you would see the aircraft turning left over IGARI or, much probably, slightly before IGARI. That simple. This is what you see every day when your aircraft is following the flight plan stored in the FMC. The right turn observed on the secondary radar and confirmed by official sources does not support a scenario with VAMPI programmed as next waypoint. No way. In my opinion, the turn from 25° to 40° is a clear indication that the aircraft was still following the original flight plan to BITOD. And if you track any other flight of MAS370 (now MAS318) on flightradar24, you can see that this is exactly what happens every day with that flight as soon as it reaches IGARI.
I have no clue what the aircraft did after it turned off the transponder and disappeared from radar. However, I think it is safe to say that it was still following its original standard flight plan WMKK-ZBAA until the last blip reported by the secondary radar.


b) ACARS off or gone, no more events logged and reported

c) pilot (or someone) programs or turns 40 degree course correction for reasons unknown, but could be to lessen suspicion of Vietnam ATC. No ACARS so no record of this
I don't get your point. What do you mean with "someone programs a turn to 40°"? If you push HDG and select 40°, then the FMC is overridden and the aircraft follows your inputs, no matter whether the next waypoint programmed on FMC is also on 40°, or maybe 265°, 190° or whatever. And which is the logic in pre-programming a waypoint clearly off-course (VAMPI) then? Sorry, I can't see the rationale.


d) as soon as 40 degree turn is achieved, then left 180 degrees to VAMPI, no ACARS now so no report of this...
"As soon as 40 degree turn is achieved" means that the aircraft was still following its original flight plan on FMC to BITOD. Very simple. I can't see any other explanation.
Obviously it may actually have turned 180° left after it disappeared from radar, however I see no evidence that a "left-turn had been pre-programmed on the FMC" as reported by Daily Mail and other junk media. The behavior of MAS370 on radar does not support this claim.

CNN were saying a few hours ago that they had reason to believe the final pings, one hour apart, were from approximately the same location - possibly the exact same location and that suggested the plane was on the ground at the final ping. They haven't "unsaid" that but they don't seem to be talking it up now.

Might explain the reluctance to provide info on earlier pings if true. At least until absolutely verified or otherwise.

Can a B777 land on unpaved surfaces?

This report here in NZ.

A B777 could probably land on an unpaved surface once!

OK Barrel, you convinced me,
it must be spilled coffee or such;

ABC NEWS is junk media;

All the official investigative, LE, and SAR operatives that have concluded it was deliberate piloting expertise in play are idiots;

FR24 and his radar plot shows are unquestionable gospel;

and all the hanky-panky that has so far left this flight mystery un-found and
unsolved, suggests that the FMC and HDG activities (we can review or just guess at) would only be straightfoward and normal and not devious or confusing.

galaxy flyer 16th Mar 2014 23:49

After this much time, I find it hard to believe it being on the "northern track" or on the ground. The US has ample satellite means of reconnaissance to identify the plane, if it ws at any known airport. An off-airport landing would likely trigger the ELT, unless it can be deactivated in flight. It can't on my plane.

ELT
 
Exsp....If the aircraft has landed deliberately on some secret airstrip, highly unlikely I guess, then it woudn't activate and the same reason as above would apply

There are 2 portable ELT in the cabin plus those in any rafts. Not sure if this ac had life rafts in the stowage. Also in the slide rafts but difficult, (not impossible) to get.

These can be activated at anytime, just put in water. Galley/ toilet sink would suffice.

The question is why we're they not activated by the crew. Most likely because the 'pilot' was assuring everyone over the pa that they were diverting etc etc.

The SAT ping being picked up was from the engine monitoring system, mentioned earlier in the thread. This is independent from the ACARS sat system which can easily be disabled. Or just pull the cb's in the overhead panel.

I really have hard time understanding your sarcasm.
If you think I am wrong, then please care to explain me exactly where and why.

Until there is concrete evidence of their evolvement, I consider the flight crew as two more victims in this horrible crime.......!

ana1936 16th Mar 2014 23:53

The single satellite ``location'' measurements that they are doing will not be able to tell that the last couple of pings were from the same location.

They will just tell us that they were from about the same distance from the satellite, i.e. on the same concentric angle circle, e.g. the 40 degree circle.

If this happened then landing (on land or in the sea) may be one explanation. Another might be that the plane's path turned to be more around or tangential to the circles, rather than perpendicular.

dmba 16th Mar 2014 23:54

The whole 25º to 40º was explained in the first couple of days with FlightRadar saying they see it as according to flight plan and it being clear for all to see in historical flight data...non-starter
