Press conference underway. Little new info.

They did say that they (Malaysians) are dispatching 2x ships with 1x SuperLynx helo between them to the southern zone. He did stress that the (single) helo can operate from either vessel!

This is a tiny, tiny, tiny fraction of the resource needed to stand even a chance of finding any wreckage. I wonder whether, if the entire US Navy were deployed to the Indian Ocean on SAROPS, even they would find any trace?

I now believe it's unlikely that MH370 will ever be found, but rather that this will be an enduring mystery that our grandchildren ask us about. We can tell them we followed it closely in real-time on long-defunct aviation forum PPRuNe...

The UK, USA and Russia have submaries capable of staying out there for many months at a time, not sure how long the recorders can transmit for but I suspect the search will go on for a long time yet, officially or unofficially.

Recorders will only ping for 30 days, and it already been missing for 9 days.

500 to 600 hours a year flight time would be about right ....

Angel Press Conference

I must say the officials fielding the questions this morning still look uncomfortable and looking at one another for inspiration.

Time

I'd suggest if there are no real developments in the next few days the international search assistance will reduce considerably. Most of the countries would have had time to get some updated aerial surveillance/intel of the area and contribute to the search effort. The fuel and resources are going to add up and with no new intel + the work done to date + satellite imagery, etc. there aren't good signs of it being found at the moment.

I'm sure digitalglobe could get some coverage there and use automated software/crowdsourcing to cover a bigger area over time.

As someone put earlier, the longer SAR goes on, the longer it takes to find something.

Press conference just told that something that seems to contradict idea that there was a signal indicating ACARS manually switched off. Just said that ACARS failed to report from 1:07am and especially at about 1:37am when it was due to report.

Did I hear they based the famous "arcs" on minimum and maximum speed?

But... what about being landed? Minimum speed is 0! I wonder how long a airplane would float. I seem to remember from the Hudson-ditching that they will float for quite some time, or was it just that they moored it quickly? Also, I guess batteries etc might get a bit waterlogged...

There has been mention of RMAF F-16s, only it appears their small but diverse fleet of combat aircraft includes Sukhoi Su-30s, F/A-18Ds and some Mig-29s. As recently as last year a sum of US$100 million was allocated to improving the Su-30s combat readiness from 65-70percent to 80percent or more.

Such data suggests the RMAF takes its role as providing aerial defence and airspace dominance of Malaysian airspace and territory seriously.
From my experience of Malaysia and the RMAF, so long as it happens between 0930 and 1630 hrs Monday to Friday.

Press also just told that the gaps in the 40 degree circle are from speed calculations.

I assumed that they were because of overlap with the other INMARSATs.

So it does seem possible that the plane ended up in the South China Sea, or Java at 8:11am as long as it went around in zig zags for 6 hours before hand.

Did I hear correct the MAS offical say the following?

Final ACAS transmitted at 1:07
Pilot's final words to ATC saying "aright, goodnight...." at 1:19
ACAS sends reports at 30 min interval so it would've been before 1:37
As such ACAS got tuned off within 30mins of 1:07 ie. 1:07 - 1:37 so could be after

As such no confirmation that ACAS was switched off before Pilot's final words.

Press conference STILL a shambles. Better than the initial ones, but still shambolic. Also with journo questions: better but still poor.

E.g. why no .ppt presentation setting out facts?; flashing up a couple of A4-sized images for a second or two; no mics for journo questions => they are hard to hear; journo: "do you hold out any hope that aircraft is still intact"; ...

Just revealed under journo questioning that:
- ACARS may in fact have been switched off AFTER last VHF comms
- these location arcs are based on minimum and maximum 777 speed from last recorded position; this seems odd as there is clearly the possibility that the aircraft can turn; so I would infer that the two arcs should therefore be one continuous one?

KL press conference today

No new change really from press conference.

the 2 iranian suspects had already been checked out and china had pax list. M'sia has asked China to look at them again.

Australia apparently going to take charge of most of Southern corridor.

France joining investigation team because of their expertise re AF442.

Northern corridor countries report a blank on their radar - however we have no idea how alert they were on the Saturday night red eye shift and therefore if that blank is true!

No doubt MH370's tale is unprecedented and therefore all bets are still on.

Above all, 239 souls are at stake including the perpetrator(s).

Map: Malaysia

Australia has been handed control of the southern Indian Ocean search for missing jet MH370, after investigators revealed someone broadcast "good night" from the cockpit after the plane's tracking systems were switched off.
Prime Minister Tony Abbott told Question Time today that along with assuming responsibility for the "southern vector" search, Australia has also committed more resources to the operation.

However, I'm sure some quick checking on actual aircraft movements into SIP very early on the 8th would soon eliminate any doubts, or confirm what they saw.
According to Flightradar24 for that time, the only a/c anywhere near Kelantan was a Chinese Eastern Airbus (MU5093) which was at 37,000ft. So unless another plane with no transponder was in the air, there was nothing else for observers to see.

Some airlines can upload a flight plan directly to the aircraft, but even so, the pilot has to request the upload and activate the route.

This just seems to me like more bad information and more bad media reporting.
Perhaps you should read the FANS Operations Manual. If a waypoint is inserted and activated in the active route a Waypoint Change Event Report is triggered in ACARS.

I think the 'Minimum Speed' is it's Minimum 'Clean' Speed Vref30+80 on the B757 & 767. 'Maximum Speed' would be Mmo (Max. Mach Operating no.). Quite a mileage difference over 7 hours between M0.78 (e.g) & M0.86 (e.g)

Can any B777 Pilots on here suggested a Range/ Endrance improvement figure for flying at Cost Index 0 in ECON?

It could have triggered the 07 transmission.

I can fly for 8 hours at 0.86 and go nowhere.
