This is the latest I could find...
Either still on route
Still searching
Or they cannot yet divulge any information they have to the Media & Public!!!


As for the Call Sign the problem with that is either using an already allocated Number, in which case I'm sure a Red Flag would pop up that there is 2 Planes with the same name!!!

Or a completely new unregistered Number which raises a Red Flag that there is a Plane flying around that is unknown to the Globe!

***RockFlier has already explained how it works, I'm sure he knows better than me if this would be easy to spot from an outsiders perspective!!!

Peace Rab!

The "changing of call sign" you refer to would be the reprogramming of the transponder mode s to show a different aircraft number. This is done frequently when a transponder is removed from a ship for repair and subsequently installed in another aircraft. It requires a computer and appropriate software. It would be an easy matter to program a different aircraft identifier or even a bogus identifier in the mode s.

so could this be taken into consideration given the somewhat intelligent manner in-which they have managed to make the plane disappear ?

Peace Rab!

what if it was from a registered plane that wasn't in the air and was on the ground or in for scheduled service ? would it still flag ?

This satellite search page shows the image multi colored, but no pixelated cube around it. CNN probably did that to incite conspiracy.

Do small civilian planes have transponders as well? Could they reprogram the transponder to show as a much smaller plane that may be kept at the local airfield and essentially keep it off the search grid because those looking at the reprogrammed transponder code would be looking at it as if it were a much smaller plane? Is there anything on any aircraft communication system that reports the size of the aircraft or is it just a given that the transponder code matches the type of aircraft in flight?

reply to post by rabourby


Well this is just a suspicion I'd had that Red Flags could be raised...
If I was to hazard a guess at speculation, considering Flight Security nowadays I'd feel certain that it would all be logged & documented where each Plane is, why it's there & for how long!!!

But RockFlier or Boeing777 would definitely have a better idea of this than me personally pal!

The problem with that scenario is that the original flight information supplied to ATC from 370's mode s does not appear to have been incorrect, at least from what information we have. To reprogram the mode s to another identifier would require inflight programming of the xpdr. As for raising flags when a different registration number is programmed, since aircraft are registered in the host nation a "bogus" or duplicate number would raise no flags unless both aircraft with the same registration number are inflight at the same time in the same area. A non existent registration would not really cause any alarms, as it just tells ATC there is x aircraft with a certain registration number, not if that registration number is valid and registered. Did I just confuse you? I did myself, LOL.

The mode s only provides registration number and not aircraft type, although through research the type aircraft bearing a certain registration number could be found. The vast majority of aircraft have transponders, but not all are mode s, yet. A great many small aircraft are not mode s equipped due to the increased cost.

Yes I posted his name before :-(

The aviation engineer is Mohd Khairul Amri Selamat, 29, a Malaysian who has said on social media he had worked for a private jet charter company.

"Yes, we are looking into Mohd Khairul as well as the other passengers and crew. The focus is on anyone else who might have had aviation skills on that plane," a senior police official with knowledge of the investigations told Reuters

im thinking its landed days ago,changes number with a smaller jet that is known not to be flying for some time ( not to raise the alarms ) and has took off undetected as a FLAG and has landed again in their desired location

maybe itsnot been reprogrammed, and just a change of transponder has taken place

So could they fly on open seas behind say MH16 Kulim-Amsterdam
with transponder off, nobody looking. Then blow MH16 outof the
sky and turn on a (identical) transponder and continue the flight as MH16?
Nobody noticing?
Long shot?

Boeing777, I have a question and I am wondering if you could answer it or point me to where I could find out.

What would it take to "clone" the electronic signature of an existing flight.

Specifically, could another jet fly along a similar vector and start pinging MH730's indent at the same time MH730 turns off it's transmitters?

If so, other than being able to achieve similar flight parameters, how similar would it have to be to a 777 in this case?

I think you can see where I am going with this.

I asked Boeing 777 this earlier, but I dont think he is around.

Does anybody know what I am talking about here? Can anyone shed any light this for me?

Thanks

I don't see them airport hopping in a plane that is being looked for by everyone in the world right now. It would not be able to land at a second airport unless it was a private airport and shut down for the day to allow just this flight in so nobody would see it. Even then they would risk someone seeing the flight coming in from a distance.

My bet is on this flight being parked in the same place it was days ago, codes and identifiers have been switched and it is waiting for the second half of its mission. If codes are tied to a particular flight path as has been said, then what we should be on the lookout for is any scheduled flight path from any airport in the region with a transponder code of a plane that may not be able to fly the distance the flight path is scheduled for. As in, they used a new code for a smaller craft that may have been at that airport, scheduled their flight so as not to throw any warning out when they begin the flight but the flight path may be too long for the plane the code matches.....not too long for a 777 though.

Could also be looking for a flight path attached to a code that is in the general direction of a major city where once the 777 gets close enough, even if the flight path is too long for the aircraft code that was transmitted it would be way too late to down the plane once they realize it has deviated.

Is it possible to give this plane a code that would make ATC believe it is a much smaller plane? I asked before but not really sure if it was answered by anyone in the know.

No private jet other than a BBJ has a 3rd seat as far as I know.

I'm lucky enough to have a friend with a Falcon 50 that I get to fly on a few times a year. Once we took a 900 when his was undergoing maintenance. That's a pretty big private jet and I think it only had 2 seats in the cockpit also.

Great question, I assume you're theorising that another Plane stalked MH370, "disappeared" it, & left without a trace!?!

Boeing777 was on ATS 5 minutes ago according the mini profile...
I hope he sees this query, it's one of the only theories I haven't heard all Week!

I have an initial idea, but I just don't know airline pingers enough.
Networkcards have a mac adress and say an ip.
You can change the ip, but the mac address is fixed.
Some hardware in the card is the mac address.
Then after a while sombody found out it could
reprogram data packets and hide the
hard mac address and fake a soft mac address.
This way you can duplicate the network card and
seen through a network cable you can't see the
difference.

Hmmmmmmm

you've lost me dude, your misunderstanding what im suggesting

reply to post by Leonidas


As far as the transponder, it would be possible, albeit extremely difficult given the timing and necessary assets. As far as the ACARS and SATCOMM, I cannot answer that. Our 757/767 fleet were not equipped with them. I have gotten out of the loop since I retired in 2008 and am way behind in the more recent aircraft systems. Sorry.

Yeah, that is essentially what I am asking.

With or without the crew's co-operation, could another plane have rendezvoused with MH370 over the Gulf of Thailand, and "Stolen" it's identity - then flew off over the Indian Ocean leaving a vague trail at way-points for searchers to follow - while the "real" MH370 then flies off in an entirely different direction with all transponders etc. turned off to land at an undisclosed location for whatever later purpose.

Then the cloned MH370 STOPS pinging the MH370 identity and lands wherever. Yemen, Diego Garcia, Mumbai etc. While the real MH730 is in China, the Phillipines, anywhere in range.

They would be searching for a plane that does not exist and was never there.

How similar to a 777 would it have to be? Would it have to be airliner size and basic configuration to fool whatever intermitant signal a radar operator might pick up? Or could it be any jet that could fly the altitude and speed as long as it sent the appropriate signal.

Far-fetched, I know.
