Please read the following for a very clear and understandable explanation of the INMARSAT <> aircraft linkage:

As I said before, we know that the FO did not follow proper procedures with respect to smoking and access to the cockpit so there is no reason to suppose that his RT procedures were any more correct.
I'm still trying to figure out why the FO is getting the blame for this? Isn't the Captain in charge of the airplane? Given what I've learned about Asian culture on Pprune, I can't imagine that the FO just decided on his own to allow the girls into the cockpit. I really don't even see him questioning a decision made by the Captain.

Now, maybe he should have questioned it - or at least reported it - but recently three "junior" pilots allowed a plane to be flown into the ground without saying a word, so....

The Satellite antenna on the B777 is at the rear top of fuselage above Economy cabin. It comprises a High Gain Antenna and a separate Low Gain Antenna both have Line Amplifier/ Diplexers boxes connected. Also connected in the same area are SDU satellite data unit and BSU and other boxes are all part of the Satellite system. All in an area behind wing and well away from the Flight Deck or nose of the Aircraft. Probably for wave propagation interference reasons.
So it's fair to say the Satellite unit is autonomous to the rest of the avionics in the aircraft.
With that in mind it's probably plausible. That it could transmit handshakes by itself, as wreckage in the sea of a broken up airframe.

Any B777 techs out there, have an idea?

Time of India reports: Practice runways for Male, Indian, Sri Lankan airports and 1 US military base found on seized flight simulation software.

What do you all make of this??
Microsoft's Last version of Flight Simulator had over 24,000 airports including International air force bases... nothing to rave on home about.

I can make a hat, a brooch, or a pterodactyl...

Can you provide a link or quote for this report? The captain's sim may just have a large generic database, world wide charts now easily fit on a 16 GB tablet computer. Many legacy FMS boxes still have memories measured in megabytes, not gigabytes however. I'm thinking he had at least a 256 GB SSD drive in his computer from the Facebook pictures.

Edit...

Just found this:

Malaysia Cops find five Indian Ocean practice runways in MH370 pilot’s simulator, BH reports

March 18, 2014

KUALA LUMPUR, March 18 ― Investigators have discovered the runways of five airports near the Indian Ocean loaded into Captain Zaharie Ahmad Shah’s home-made flight simulator, a Malay daily reported today.

An unnamed source told Berita Harian that while it was too early to make any conclusions on the new finding, it was still considered an important element in the probe on the whereabouts of the plane and its 239 people.

“The simulation programmes are based on runways at the Male International Airport in Maldives, an airport owned by the United States (Diego Garcia), and three other runways in India and Sri Lanka, all have runway lengths of 1,000 metres.

“We are not discounting the possibility that the plane landed on a runway that might not be heavily monitored, in addition to the theories that the plane landed on sea, in the hills, or in an open space,” the source was quoted as saying.

Although Defence Minister Datuk Seri Hishammuddin Hussein denied yesterday that the plane had landed at US military base Diego Garcia, the source told the daily that this possibility will still be investigated based on the data found in Zaharie’s flight simulator software...

ZAZ, the runway on Christmas Island is easily big enough. It's not a scheduled operation

Microsoft Flight Simulator contains thousands of runways "out of the box".

Maybe they meant "add-on airport packages" - you buy them to get more detailed visual scenery around certain airports. It tells absolutely nothing - you don't really need these bells and whistles to practice landings, and every serious flight simulator enthusiast will have a lot of such scenery packages installed.

Microsoft Flight Simulator doesn't have a built in FDR, so I doubt they will find out exactly what he was doing with it. They might be able to figure out the rough areas where he was flying the last time by looking at the "last accessed" timestamp of individual scenery files. But that's pretty much all you can figure out - unless he he explicitly recorded his simulator flights.

Two-thirds of passengers on board the missing Malaysian Airlines plane have been cleared of any links to terrorism, according to officials.

This thread is now very hard to follow with multiple in depth posts covering every 'guess' known to mankind, I mean since the jet went missing there's been approx 1 post every 3 mins, 24 hrs a day. Christ is this the biggest aviation mystery/event since 9/11 or what?

All I wish now is for the relatives to find some sort of peace with all this
Can't imagine what they are going thru:-(.

It's the biggest guessing game I've seen/heard in aviation since God knows when!

Persistent airborne position reports would allow aircraft to be tracked but not necessarily alter the outcome of an occurrence for the passengers.

From a safety point of view, better for an airline to spend the money on pilot training.

From the New Straits Times:

"One Orion commenced searching the Indian Ocean to the north and west of the Cocos Islands yesterday. The next sweep will take place this evening as an AP-3C Orion transits from the Cocos Islands to RAAF Base Pearce in western Australia," he said in a statement yesterday."
Abbott said he also informed Najib that Australia would make additional maritime surveillance aircraft available to extend the effort to locate MH370.

It's a despairingly isolated and vast area to cover.

NST also reports that Malaysian investigators are currently favouring the theory that MH370 headed north.

normal atc outage

According to historical data this flight normally loses ATC contact around the area of the last report. Most flights regain contact just short of the Vietnamese coast. It was coming right at the time of last report, towards the oil rig. That lends credence to his claim the plane was coming straight at the rig, not moving left or right from his perspective. I would imagine the ASW towed array sonar on one of the A-B class destroyers could pick up the pinger if they ran down that bearing line to the oil rig. Anyone know what frequency that thing pings at?

Sheep Guts..

The Low gain and High gain antennas require a couple of things to work--

1/ ADIRU aligned so the sat dish knows where to look for the satellites
2/ Power supply from the Aircraft

So NO it would not work on a crashed Aircraft in the Sea unless the above requirements were met!! Yes not likely I'd say.

p.s. Low gain for data, high gain for data and voice.

You can save a flight so you can load it and be straight on approach or finals etc. perhaps flights were saved for approaches or landings at certain airports. That would raise the significance somewhat.

I certainly hope Boeing is running flight simulations using MH Aircraft spec data to calculate exactly where they think it would run out of Fuel considering all the data they know about the flight profile from Radar traces. ( FL295 over Penang, 5,000' later on etc )

They should be able to see the expected Range.

AMSA media release with links to search area maps.

(It seems you can not show their maps directly on PPRuNe.)
