As a LAME, i just accept that no one thanks me for ensuring the aircraft i inspect and repair are safe to fly. Certainly I'd say its very rare for a pilot to say hey man thanks to keeping our aircraft safe to fly, your the best.

If can be honest i get plenty of groans and moans when i fix an aircraft faster than the crew expected while they watch their duty hours tick by hoping it runs out before the aircraft is fixed.

While speculation is just that, after an accident or incident speculation is rife, and the first thing to be assumed is that something has gone wrong with the aircraft. Some lazy tech has done a dodgy repair.
So by asserting that the crew has done nothing wrong asserts that someone else has.

The basis of all modern aircraft designs is that no single failure should cause an aircraft to crash. Multiple compounding failures are incredibly rare.

So to me its swings and round abouts.

To the land of pings
 
Do the Malaysian authorities read the experts on this commentary. So now the airplane is placed near the entrance of the Malacca Straits at 5000 feet before it goes off radar. Now not a southbound turn right over Indonesian radar has to be accounted for, but also a climb to conserve fuel to get to the land of pings. How do these dots connect?

rampstalker I agree on what you just wrote below. I have seen many times that posts from those accepted with ease and many of us still keep trying and putting efforts to express our ideas here.:bored:

I see very little support for the crews on here from other flight crews. Or is it because they are not English/Oz/American.

Prime Minister Tony Abbott announced his Government was “very confident” that missing flight MH370’s black box recorder had been located.

But his statement seemed to be at odds with a statement released just minutes afterwards by the head of the MH370 search team, Air Chief Marshall Angus Houston.
AND


Government sources told news.com.au they were confident the Prime Minister’s remarks were factual.

It is understood search teams will not announce the discovery of the black box until the flight recorder has been sighted.

Mr Abbott is also due to meet with Chinese President Xi Jinping for a state dinner in Beijing tonight. He said that he would hold back on announcing more information until he had briefed the president, out of respect for the many Chinese families who had relatives on board the flight.

“I look forward to providing President Xi with the latest update when I meet him in Beijing this afternoon. We are confident that we know the position of the black box flight recorder to within about a kilometre.

More than likely.
The best thing Abbot did was to appoint Angus Houston and he should now shut up and let him give out the facts as he has been doing, calmly, clearly and unambiguously.

I never heard of Angus Houston before this tragedy, but I am very impressed. His leadership has been a tonic, bringing order to an investigation which has seen far too much rancour, accusations and misinformation.

Which is why he ended up head of the Armed Forces is Aus. He has publicly and vocally stared down politicians in the past at a lower rank and still made it to the top job. He is also a decorated SAR pilot so knows what he is talking about.

So marinetraffic has HMS Echo motoring straight into the search box and stopping at -21.0061 104.0151. Status is stopped in vessel details box.

orbitjet 11th Apr 2014 07:25

You do understand that marine traffic is not getting constant coverage as its dropping in an out of VHF aIs coverage.

Unless you are using the satellite feed that costs $299 a month or a free trial, but then again I don't think the sat feed is live.

As i look at HMS ECHO it shows last info received was 3 hours ago.

I agree with your analyse entirely.

I will try to reproduce a redacted version of a previously deleted post.

At FIR/ATC changeover point somehow ACARS and ATC transponder and VHF fail to respond.

Just because VHF coms or transponder elicit no response does not mean they have failed; ......
If you don't answer the radio doesn't mean the radio is dead.
If you turn the transponder to STBY doesn't mean it has failed
If ACARS is deselected from VHF programing .........? and you don't subscribe to satcom ?


Who is operating the airplane?

500N 11th Apr 2014 07:28

Re the ships in the two search areas.


The Chinese ships seem to be still searching the western search area.


I see the two supply ships are now together and a big oil tanker on the way
to the search area, heading for the supply ships.

I don't see an answer yet so this is my best guess:

The aircraft or parts would be secured using robots and strops.

The aircraft would be hoisted slowly off the bottom and additional strops put in place. Further slow hoisting would take place until deep divers could reach it and check strops and add additional support as necessary. I would not expect them to enter at this stage as any failure could trap them . . .

Once near the surface they may attach buoyancy chambers and slowly inflate until slight negative buoyancy is achieved. Further raising and inflation until the aircraft is virtually on the surface.

They might enter at this point however that might also cause parts to break off and be lost.

The size of the aircraft would probably dictate provision of a barge and probably removal of wings and tail while still suspended on the water.

@orbitjet


Status is stopped in vessel details box.
Yes I understand the free feed is several hours old but the status as of 3 hours ago was 'stopped' NOT 'underway'.

Another interesting tidbit
HMS Echo, Tireless Work Round the Clock to Find Malaysian Airliner MH370 >> Naval Today

HMS Echo’s hi-tech sonar has been specially adapted so it can pick up any transmissions on the black box’s frequency – this is the first time Echo’s sonar has been used this way and so far it has located several possible contacts – but sadly none of them proved to be from MH370’s black box.

ie from the Haixun01 contacts a couple of days ago

JoeBloggs2 11th Apr 2014 08:02

That was HMAS Toowoomba as far as I could see it tracked straight back out to the debris search area. One would assume that it would be nearer to Ocean Shield or Echo if it was going to transfer AUV's... [or launch and recover them itself]

You would think that the Germans and / or US would claim the publicity if they where here already...

Lifting MH370 .... Underfire
 
How would we go about lifting mh337 debris from 4,000 blaahahab meters?

AF447 recovery produced (75) human remains.

Wader2 11th Apr 2014 08:06


Some massive recovery ship with crane capable of 500,000lb lifting capacity arrives on-site
Actually weight is really insignificant compared with other deep sea recoveries; it is only 250 short tons. More significant is the size.

If they do recover the fuselage to near the surface then a lift not that difficult.

Whole destroyers and frigates have been brought home on barges. IIRC HMS Nottingham was one and USS Cole another.

Three deep-sea submarines used to search for wreckage of the crashed Air France Flight 447 have also been sent to aid in the search for MH370.

The three "Abyss" type submarines can dive to depths of 6,000m and stay submerged for up to 24 hours.

Forgive me but is it at all significant that the area where Echo is now 'stopped' looks a paler blue than the surrounding ocean?


Does this mean it is shallower?


I am hoping this might mean recovery would be easier than if it were outside of this area.

PPRuNeUser0171 11th Apr 2014 08:22


Does anyone know if the optic fibre repeaters on the underwater submarine cable SEA-ME-WE3, which runs from Perth through the search area to Jakarta, emit any noise? They are powered by internal DC power. Could they be causing interference?
They shouldn't have any interference as they are high capacity datalinks and any interference would degrade the throughput. Those cables are normally covered in protective layers to shield any interference and then buried in a trench at the bottom of the ocean to further protect them.

http://www.marinetraffic.com received its last data feed 3 minutes ago and its showing HMS Echo stopped on the border of the search area and Ocean Shield moving towards its location at 1.6kn.

Towing the pinger locator again???

Sheep Guts 11th Apr 2014 10:15

Orbit jet,

Live Ships Map - AIS - Vessel Traffic and Positions - AIS Marine Traffic received its last data feed 3 minutes ago and its showing HMS Echo stopped on the border of the search area and Ocean Shield moving towards its location at 1.6kn.

Towing the pinger locator again???

I'm guessing HMS ECHO is all ears at the moment listening for the ULB all engines stopped. And I think your right about Ocean Shield still towing the TPL-25.
