Maybe the Satellite antenna on B777 is smart in itself and can send basic handshake pings to the Satellite. Only a B777 avionics guy could tell us any takers?

CX/KA normally tanker fuel to PEK too.
It's super expensive to buy it there. I see no issue if this was MHs practice. |
Once more the lowdown on SATCOM
Please read the following for a very clear and understandable explanation of the INMARSAT <> aircraft linkage:

So, to help locate this aircraft, you'd be willing to put future flights in danger by removing the ability of the flight crew to address a problem?
I'll wager as an industry we've seen more unit malfunctions, fires and overheated equipment than we have rogue pilots/terrorists turning systems off to intentionally hide. |
But, after initiating the left turn, could the flightcrew have been cycling through the XYZ checklists to eliminate the causes and switched it off themselves, and been overcome/forgetting before they were able to switch it back on? Then the fire goes out The problem is that one begins to pile one miniscule probability on top of another miniscule probability in an additive fashion hoping to get to one (certainty). But in fact statistics multiplies probabilities. So the odds of one rare event followed by another rare event is more rare, not less rare. So the odds of the transponder failing followed by ACARs failing, then a fire breaks out, then the crew is overcome by smoke just as the fire burns itself out is to be so wildly improbable that it beggars belief. That doesn't mean it didn't happen. Even one in a trillion odds will come to pass sooner or later over an infinite number of trials. But speaking only for myself I would not be dedicating scarce resources on such scenarios. The other poster is correct when they said I was being "too dogmatic" by saying a fire is "not possible" because anything at this stage is possible. But it's way down of my list of likelihoods. |
With 50 m or more of water over mud. Nope. The plane ail fragment if it hits the water at high speed. Some of these pieces will be small with little momentum. Some won't be very aerodynamic (? hydrodynamic). Can you see a detached aileron flying through this much water and digging itself into the mud. The other wild threads that are being pulled though really do deserve to be examined on another forum. IMHO of course. |
GarageYears... Thanks for that article. Makes sense that the protocol to keep the satellite link subscribed is in the satellite transceiver itself so it will ping as long as it has power, even without incoming data.
Hopefully someone is looking into how ARINC 629 cables failing could make it appear that ACARS and Transponders were turned off by a human. Failure of that buss would also mean that the VHF and HF control heads (as well as others) on the flight deck could not connect to their LRUs. Even a short duration fire could cause a real mess in a hurry. |
This just in!!!
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?? :sad: |
Look, let me put to bed the tyre failure/overheat/fire scenario.
The 777 is fitted with: 1/ TPIS, which stands for "Tyre pressure indicating system" which is monitored by EICAS, the crew WILL get a message if a tyre deflates. If they suffered a major tyre failure on takeoff they would have felt the problem ( especially if it was a nose wheel tyre ) and then received an EICAS message. 2/ if there was a Wheel Fire in the main Wheel Well they would get a EICAS Fire Wheel Well Warning and they would have followed the QRH procedure and then declared a Pan or Mayday as required. This would certainly NOT include climbing to FL450 to put out the Fire!!! :mad: ( the QRH from memory says to slow below MLO .82/270kias and extend the gear, if the warning continues LAND ASAP. ) I've had tyres deflate on T/O at MTOW on a 77W out of LAX, no big deal. We had a slow deflation and nothing found on the runway, we continued. Tyre was flat on landing. |

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. 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? |

XMAS IS
LOL
Runway can take a 737 or BAE111 |
What do you all make of this?? 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 :rolleyes:

What do you all make of this?? :sad: 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.
Missing Plane: Families In Hunger Strike Threat |
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! Wmk2 |
