A while back there was a press conference by the ship owners shown on UK TV.

I only caught the end of it but the owners said something like " Do not expect any further information from us as all findings will be passed to the SAR team"

Quick question
 

The pace of this thread has finally got ahead of me, I awake each morning with pages and pages of posts having racked up. Hidden amongst all the repeats, regurgitations, speculations and phishing media posts exist a very small group with some really insightful and knowledgable posts. Addressing this latter group, can I ask if any evidence has ever emerged to indicate MH 370's final 08:11hrs ping was emitted from a point on the southern arc rather than the northern arc?

Lazerdog spake, "Perhaps the only way to find MH370 is if the US Navy sends a sub into the area. They would have the technology to hear the pinger a long ways off. "

No, they wouldn't. Manned submarine and air launch sonobuoys are designed to listen for much lower frequencies from submarine and ship machinery that travel much further in water.

The FDR/CVR pinger operates at 37.5kHz with a maximum detectable range of about 3 nautical miles (18200'). Given a water depth of 12000' a surface listening device would have to be within about 13400' (2.2 nautical miles) laterally to have a chance of hearing it. Put a manned sub at, say, 1000 feet under an you increase that lateral range to 14500' (2.4 nautical miles). Even then you'd only "hear" it if ocean conditions were favourable. The oceans loves to bend and distort sound waves.

A deeply submerged ROV (say at 10000 feet) with appropriate equipment is the best option only when they have a good idea of the location.

BTW: In a past life I was the engineer overseeing software development for the AP-3C acoustic processing systems.

No.

The problem is, no one starts a thread like this and expects it to go this long. I've seen this on every site I've been on.

If people really want to keep discussing certain aspects, such as the Inmarsat pings, I would suggest you break up the topic in different threads. It's been working on other sites, and it tends to break up the clutter of regurgitated theories and questions.

Investigation: AO-2009-044 - Air system event - Beechcraft King Air C90 aircraft, VH-TAM, 74 km NE of Perth Airport, WA, 16 July 2009

I asked because of how big the datum became after last known position, and because whatever the entirety of the search team(s) have before them as information to work with, there is still a lot of unknown.
There may be a significant uncertainty regarding the efforts 2000 nm west of Oz ... but these efforts are quite possibly based on best possible information.

Grateful I am not the guy trying to coordinate this search effort. Nightmare.

Not exactly the case with AF447 it was descending at over 10,000 ft per minute so around 120 mph vertical velocity while the aircraft was in a slightly nose high attitude with a forward speed not much different to its vertical speed. IFF MH370 ran out of fuel and did a flame out glide to the surface it has been opined in a previous post that the descent rate would be around 300 feet per minute with a just over stall - say 190kts forward speed. Not comparable 'ditchings' at all.

Only one person in cockpit?
 

Another puzzle is it would be assumed only one person has gone a bit crazy when the other pilot left the cockpit. However top of the climb is a bit soon to need a nature break.

What an understatement. Not only is the wording not exact, the terminology is all wrong. I have downloaded and listened to an hour of Lumpur control from liveatc.net and not once did anyone use the phrase "Kuala Lumpur ATC". All radio traffic uses simply "Lumpur".
Unfortunately liveatc.net only has a receiver on 132.8 and the NE sector is 132.6 so there is no MH370 traffic available to listen to.
I find it unfortunate that they feel that the transcript, along with the last ACARS message are some big secret.

Hoegh joins MH370 search -Tradewindsnews.com


Plus ...( from 19 Mar ?)
Here's a full report on the press conference with the Norwegian ship's owners:

The owner of a Norwegian car carrier said it planned to search through the night for two large objects sighted off Australia that could be debris from a missing Malaysian jetliner, despite the official search being suspended because it was too dark.

The Hoegh St. Petersburg was the first ship to arrive in the area where the two objects were spotted by satellite four days ago in one of the remotest parts of the globe, around 2,500 km (1,500 miles) southwest of Perth.

"We will continue searching during the night at reduced speed and with all spotlights available, and we will increase the speed again when the light comes back (around 2300 GMT)."

Ingar Skiaker, Chief Executive of Hoegh Autoliners, told a news conference in Oslo.

"We have not had any report of any finds, but if or when they find something... the captain will report to the Australian authorities first," he said.

Hoegh Autoliners said as far as they knew theirs was still the only ship in the area in the southern Indian Ocean, with other ships on their way and expected to arrive tomorrow.

The Hoegh St. Petersburg would stay to help in the search for as long as it was needed, a company spokesman said.

"We are thinking about those who are waiting for news. We are thinking of the relatives," Skiaker said.

The car carrier was on its way from Madagascar to Melbourne when it got a request from Australian authorities to assist in looking for the objects.

So...
 

...launching from Perth in a King Air has its risks, eh?

Mods: Feel free to delete (as if you wouldn't...).

300 ft /min on no engines ? That is about 64:1 glide ratio . . . I'm sure you meant 3000 ft/min. :ooh:

Weird/non-standard translation? So they claim all communications were in Mandarin? And then there's obvious spelling errors like "Hu (sic) Chi Minh city". Seems a bit weird? It's hard to believe anything the media report...

Fire
 

I got curious and did a research on the antenna locations on the B-777. As I imagined, all the comm related antennas are under the "belly" and directly under the forward cargo bay. All the sat comm antennas are, of course, on the top of the fuselage.

Could it be possible that a fire in the front cargo bay destroyed the wiring "traveling" to the lower antennas? The upper antennas continued sending signals to Inmarsat and dense and toxic fumes took over the cabin and cockpit.

If dense smoke takes over the cockpit, it is impossible to fly any airplane. Change course on the FMS with almost no visibility very difficult, low fire but lots of smoke. For how long a crew can resist?

Antennas out?

Re: Telegraph transcript. According to that the plane climbed 35000ft in 8 minutes, roughly 4300ft/min. A bit extreme?

Two things I note from the translated twice transcript.

1) 370 call level FL350 at 01:01 and then again at 01:07:55

2) The previous hand off was answered with freq. followed by "Copies that" "copies that" was used to acknowledge instructions 5 times until the hand off to KL RADAR. It wasn't used in response to the climb clearances and it wasn't used in response to the last hand off.


I wonder if the PF changed during the climb or perhaps after the 01 level call. Other pilot not sure if they had called level so made the call again.

Nothing really obvious and because it's a translation of a translation "copie that" may well turn out to be "Roger".

Are you absolutely 100% sure that is indeed the case for either of the pilots on this flight? :ugh:

ENGLISH > MANDARIN > ENGLISH

I think I would choose S90E0 if I wanted to go to the pole. A waypoint behind the pole could do as well something like "Tierra del Fuego". If the south pole is chosen, the track must go straight down a meridian. If the flight path was a great circle or a constant heading path should be deductible by the ping arcs (hope that word is not banned yet).
