If any wreckage is found floating, would it be possible to drop bouys to listen for the CVR/FDR pings (in the right frequency band)?
It would be possible, but that would be a bit pointless given that the 'wreckage' is probably over 100 miles away from the crash site and even if it were right above it, it's unlikely a pinger would be heard from the surface in water of that depth.

@ xcitation


Looks like the Malaysians aren't the only ones with issues releasing data!
Nothing to hide, just thought it wouldn't be wise. I've never been convinced by the assertions that it went west, let alone that it followed that waypoint pattern. But when someone brought it up again I just plotted it out of curiosity.

Now it seems the investigation has moved on and the Australians are searching in what seems to be a likely area for the aircraft to have ended up. And now potential debris has been spotted, I think it's now just a waiting game.

The sea floor in the area where the debris was discovered is around 3000 metres and flat and featureless.

3000 metres is well within range of ROV's.

Here is a marine chart image of the seabed from a screenshot.

Thanks to PJ2 for taking the time to explain to me how to post it.

I understand each wing tank of the 772 can hold 35000 liters, if they didn't rupture that's a potential for 35t of buoyancy.

From the US, extensive coverage this morning on the voice of conventional wisdom "Morning Joe" (cable, MSNBC). Preliminary reporting indicating that nothing was positively identified on the first pass due to weather. Live report from OZ as I write this.

All the Best

That is true. It might hence be interesting to know how much of a custom tailored agreement MAS have with their database supplier.

Still, going south for hours if planning to go north should alert a person that is apparently able to operate a 777's FMC.

can anyone, confirm that data collected from the pilots simulator indicated he had made several approaches to Diego Garcia?

News interview with flight crew on Channel 7
Summary
Location is approx 1500 NM Sw of Perth.
Flying at 100ft asl
They had all sensors operating
Channel 7 have a crew onboard an orion that will return at midnight.

Route mirrored in both latitude and longitude at IGARI
 
The possible debris location is remarkably close to a potential reflected route after the IGARI waypoint:

Are you talking the Aussie AMSA Press conference or some other TV show ?


If Aussie, I don't think he said today, I think he inferred they had had then a while - few days - while they were analysing them.

MH370 range
 

For this aircraft to have flown to the current target area it would have travelled about 7,000 km.
Is that possible? Even with a generous allowance for sea drift, is that possible?
The return journey from KUL-PEK is around 4,600 miles so if MH370 was tankering fuel, with reserves, it could easily have travelled 7000 km.

Think he corrected himself," received the information today but was unsure of date the pictures were taken "

OleOle 20th Mar 2014 11:00

drift
 
I wouldn't expect surface current to be more than 0.5 - 1 knots in that region, amounting to lets say 150 - 240 nm in 12 days. If drift wasn't in a straight line it's even less.

Those drift buoys are exposed to the wind as well, their behavior shouldn't differ much from debris.

Where in that article does it say that? What it actually says is (my italics):


Some of the information already recovered from the simulator suggests the pilot may have practised landing at a remote US military base on Diego Garcia

Speed of Sound 20th Mar 2014 11:17


So, were they tankering fuel?
Surely this point has been determined by now
The Malaysian authorities confirmed that there was nothing unusual about the fuel uptake for this flight and the perceived wisdom when this was discussed a few days ago, was that MAS would pay less than 30% for fuel at KUL than they would at PEK therefore it would make no sense to buy fuel in China.

Space Jet 20th Mar 2014 11:18

Channel 9 will have a "Special Report" from a reporter who was on board one of the Australian search aircraft after the footy show (in twenty minutes).

This is Melbourne so not sure if other states will have it but I think they would.

So what? I've done approaches with a 737-800 onto a carrier in the pacific, doesn't mean I'm actually going to do it.:ugh:

Token Bird 20th Mar 2014 11:20


Surely its obvious looking at the data, he either flew there or he didnt
There was something a few days ago about how he had certain airports in his database, including Diego Garcia. I think it's likely this article has sprung from that. Airport is in database = may have flown there, along with all the other hundreds/thousands of airports that were probably in his database :rolleyes:

"Malaysia Airlines plans to fly relatives of the passengers and crew to Perth if the objects are confirmed to be from MH370, the company's chief executive Ahmad Jauhar Yahya has said."
