Missing Malaysia Airlines jet carrying 239 triggers Southeast Asia search

[tifino]

The civvie radar system has the controllers (ATC) viewing the A/C CallSigns, which are all that's seen onscreen, along with sqwark codes - all of which are Secondary info. If the air traffic controllers had all Primary on at all times, the screens become overly cluttered, especially with radar returns that are not even aircraft. The civilian radar system that employs Primary returns for display is the Weather Radar.

As far as 'seeing' someone, a Civvie controller is advised of someone of interest in his Sector, when they 'Sqwark Ident'. Each controller has his own Sector of responsibility, and looks at what he is told to.

In relation to Secondary failure, the most likely scenario would be that an aircraft reports, or is reported by, another authority, that it's transponder has 'failed', and until the Civvie Controller knows there's an 'invisible' aircraft flying through his watch(his Sector), he won't see it, or even know to look for it.

I've worked in a Tower staffed by a co-operation of Civilan, and Defence, ATC controllers, each group having their own set of SOPs to follow, even though they are all using the same Radar system. In our case the civvies were using our MilitaryRadar, but using it their way - Secondary Only.

I'm only recalling what I have seen myself, at the sharp end, as it were...

cool. We've had several experienced pilots on this thread, now it looks as though we have someone with hands-on experience with radar. Interesting. And a new phrase: 'Sqwark Ident' I might use that for naming my next child.

Just out of interest the word is "squawk" and not "Sqwark". Squawk is a 4 digit code that can be set on the transponder at the request of ATC, to signal a hijacking, etc - it then replaces the aircraft's prearranged tranponder code.

yep, you're correct in what you may have googled. It's a hard habit to break away from - use of a phonetic term, for many things, often gets used at work here in uniform

It often happened in congested airspace, and/or times R/T is hard to hear, and the Controller is calling the fellow on the radio to squark... to show which is he on the screen.

On our screens we can display multiple lines of the **** code,well - on the Military side of the fence anyhow.

The **** codes themselves, for Emergency, Hijack etc are respectively pre-defined, & no need to digress into them at this time eh!

- maybe that is what was deleted from that earlier Post?

Strange, the malays, not saying much, especially as the malay MinDef radars had them on screen, yet no report of them having even attempted to make contact for the period(s?) that the A/C was on-screen...

Mr Anwar held a press conference a month ago where he angrily lamented that Malaysian radar was not properly used re; the missing plane.

Malaysian defenses were asleep at the wheel, and/or Malaysian authorities are keeping crucial data under wraps. Methinks it's both. I'm looking out my window and there's a little orange bird carrying a sprig of straw to build its nest. Life goes on......

An oil rig worker who claimed to have seen a fire in the sky on the night Malaysia Airlines flight MH370 disappeared has been fired, with police confirming his claims are being taken seriously.

...worker tells the truth, then gets flamed - but I guess that's the new world order of how things are how they are for now

...and Anwar now appears as the good guy. Always getting flamed for exposing that which doesn't look quite right.

I remember the days, decades ago now, when he was first rising to popularity. The little guy in the islamic cap and dress verus DrM in the suit and tie.

My, how things have changed since those days of Anwar as Deputy PM on the other side of the House...

The plane was not shot down by the Americans. Do you think the US could fly around territory under the control of other countries without being noticed or without notifying them? Do you think that they start shooting live ammunition at planes without consultation from others? Do you think that the somebody, especially the Chinese wouldn't be screaming bloody murder if they thought their citizens had been killed by the US?

The area was not US controlled airspace, the US would have little access to information on flights in someone else's airspace. They would take an interest in monitoring any activity around their ships, but it's not their airspace and it's not their responsibility to identify what is going on. MAS wouldn't be notifying the US of planes flying near it's ships either.

Ah but Diego Garcia is American airspace and the Rolls Royce engines recorded around 4 hours of operation from the last point of contact which is around 2,000 miles. Diego Garcia is about 2,100 miles.

Just sayin'

There was NO recording of 4 hours of operation by the Rolls Royce engines. ACARS did not transmit engine data again after the Top Of Climb report, before MH370 went silent. There is evidence that the engines continued to function for 6-7 hours after that, but only from the Inmarsat analysis of the Sat pings.

I beg to differ, the engines, as in all Rolls Royce engines fitted to civilian airliners, were in constant contact with Rolls Royce whilst they were in operation, and these engines were reported by Rolls Royce, soon after the incident, to have been in operation for four hours after the last point of contact.

What is your source for this information ? What you say is impossible. Rolls Royce engine data for MHS is transmitted via VHS. VHS was not operating after the A/C went silent over the Gulf of Thailand.

[tigermonkey]

Somewhat old news. Australia has released the request for tender for the private search for MH370. The tender closes on June 30. They do not say what their acceptance criteria will be for the successful bidder. I do hope that they will not go for the 'lowest bid' but for the apparent best/most experienced/ best qualified. I shudder to think of the results if they accept only on the basis of price.

Tehder request is here:

Categoric dismissal by you of oil rig worker story leaves me unimpressed.

Sorry if I gave you the impression that it was a "categoric dismissal": it was not ! It was a decision based on the facts available to me, which led me to believe that the oil rig worker may have seen something, but it could not reasonably have been MH370. That decision was based on the laws of physics, and knowledge of visual acuity of human beings. Hence I have an alternate opinion to yours, which is fine with me, but unfortunately seems to cause you some discomfort. Sorry for that !

• Malaysia Airlines Flight 370 Search Zone Poised for Another Shift

By Andy Pasztor, Jon Ostrower and Daniel Stacey

For the third time in less than three months, investigators looking for Malaysia Airlines Flight 370 are poised for a shift in search areas after revising some of their basic assumptions, according to people familiar with the process.

The latest rethinking, these people said, reflects inescapable uncertainties about the speed, flight path and altitude of the Boeing 777, which mysteriously veered off its flight plan on March 8, flew on for hours and is believed to have run out of fuel before going down in the remote southern Indian Ocean carrying 239 people.

But until the aircraft is found, such assumptions are still educated guesses. Changing the assumed speed, trajectory and altitude, though, can result in sharply divergent underwater search areas, possibly taking teams significantly south or southwest from where they focused their efforts in May.

Application of the laws of physics are fine. IF the data is correct.

Were not the Sat Pings from ASCARS trying to connect? as per Inmarsat..... As everything else was turned off!

Hmmm.... Are you retired?? If so I guess your Employer is reliefed And if your still working... I can bet they are counting the Days till you do retire. As it looks contrary to your own statement.... Unless anyone agreed with you about any subject relating to MH370... You Blatently disagreed! If you dis agree start at #1 and read them all again!

Agreeing with you would help prove there is no evidence anywhere of where the plane is now. So as Austrailia is revamping their thinking, why is it not logical for readers to do here also. If their comments are base on even some "Off Centered" Logic. One one in pointing fingers at anyone... We just want "ALL" possible senarios honestly looked at. I believe you would also if you had Family onboard....

a bit like " it was God musta shot me down over the Vatican" in Rome, Italy

[F4UCorsair]

The head of the organization coordinating the search in Australia, former Chief of the Defence Forces, Angus Houston, has just said that it could take two years to find the aircraft!!

I still contend that if it crashed out of control, not actually 'landed' on the water, there will be significant wreckage washing up....somewhere. That may also be the case if it was put down on the water by a crew member, unless he was very lucky.

Edited June 10, 2014 by F4UCorsair

[boomerangutang]

Have there been other plane crashes (or similar) in that region of the Indian Ocean? If so, where would debris most likely get washed up? It might be a moot point, as the closest land mass is west coast of Australia, and that's a long way from - the purported crash site. Since all other surrounding regions are sea, then it's more testament to the skills of the pilot ....assuming he ditched at a place and in a manner - to leave as little debris as possible.

Fugro joins search for missing Malaysian airplane

Tuesday 10 June 2014

Geotechnical survey group Fugro is joining the search for the missing Malaysian airliner which disappeared on March 8.

The Leidschendam-based company is joining the search at the request of the Australian transport safety council which is leading the investigation.

Fugro will search a 60,000 square metre area of the seabed to the west of Australia with the Fugro Equator, a specialist ship containing advanced echo apparatus.

It was in this area that 'pings' were heard which are thought to have come from flight MH370's black box.
