have the bbc managed to get inside information from inmarsat? |
The Chinese appear to have other resources to confirm the impact. |
At this rate, passengers will soon be required to switch their phones ON during flight, and de-select Flight Mode.

Is it possible the Inmarsat pings continued to be sent after a crash, or successful ditch at sea attempt?

Airspeed and pressure altitude both come from the air data box. Would be 429 data between the air data and instruments and transponders.
Mode S sends altitude out 2 different ways the mode C reply in 100' increments and in mode S in 25' increments. If they agree ( say 35,000 and 35,025) the reply is considered valid. If they disagree ( 35,000 and 31,475) the reply is invalid. |

It was a moonlit night so a change of course would be obvious from the half moon. |

Pitot tubes do not feed altimiters. Pitot tubes always feed separate systems. That is why you have more than one. Towed array sonar does not do what you think it does. Aside from that, sounds like you know what you are talking about, Captain.... |
Cabin crew.
Whilst we may consider the actions and motives of the flight crew, what about the cabin crew - have they been considered.
I'm cabin crew, with a ppl, and an interest in aviation. I know the basics of flight. I believe I would be capable of altering the auto pilot coordinates. I'm certain that I could not land a B777 without considerable training. Maybe one of the crew thought they could? Importantly, as a third party hijacker, I know exactly how to enter the flight deck and would my request would not raise any suspicion. Particularly if I'm equipped with two cups of tea at the top of climb. Just, another, thought |
Further to the moon set times etc, most passengers are not aware of any of that, far less the flight plan route. A turn is just that, a turn on a route, and they do not question it. Turns happen when you are holding, even on airways at higher than normal holding altitudes.

Oh captinjim on #4 if nothing is sent from the air data the mode C will only send out the framing pulses with no data giving an invalid not 0'

Question for T7 Drivers
Since I have no operating knowledge of the bird, is it, or is it not, possible to disengage SATCOM from the flight deck?
Assuming a hostage/hijack scenario, I'm wondering if it was not possible to shut down the SATCOM, if it was overlooked, or perhaps left on deliberately by the crew. All conjecture I know, but still an interesting line of thought. |
It can be disabled by a check-box in an on-screen menu.

The fact that the transponder is instantaneously reporting zero while the a/c is 7 miles high in the sky is a key piece of information. The lack of radio reports while the transponder is still working would indicate an in-cabin event which precluded a radio report. Then over a three minute period the transponder ceases reports all together. It looks like this geographical area is where transponder updates become sketchy as some historic tracks lose data up to a point just short of reaching the Vietnam coast. All of this points to a rapidly deteriorating electrical system in the aircraft. The oil rig observation is interesting. The observer is over 300 nm away but it is a dark, cloudless night. His observation of a burning plane would be down near the horizon. But his comment that, from his vantage point, he could percieve no lateral motion lends credibility to his report as we know the plane had just turned more in his direction, head on along with the indication that the event took place much further away than it appears. If one of those US destroyers in the area is ASW equipped they should run their towed array sonar along 060 to 075 from LKP. The idea it was still in the air for 4 hrs lacks any published data... same as the "military radar" theory. I would love to see more published data that they obtained. However, what about the predicted flight path put together by the US military published earlier that suggests the missing plane was heading towards Andaman Islands? |
I have noticed differing posting of the last 10 or so flight data points. The original postings in the early days of this event display the last 2 updates with a flight level of zero(0). The recent postings and news reports I've seen in the media seems to fill in those two values with the same 35,000ft as the rest of the 10 updates rather than the original reports of zero. This maybe a key oversight. And why so many "experts" are focusing on other areas. I believe the last two reports of zero for altitude along with a constant reading for air speed may provide insight. I thought we had disposed of this nonsense about 3,000 posts ago. :ugh: |
Inmarsat
One would think the statement that deserves the most attention at the moment is from Inmarsat, when they confirmed receiving signals from the aircraft:
Inmarsat statement on Malaysia Airlines flight MH370 - Inmarsat The lack of any detail, given the magnitude of the event and the lack of other leads, is surprising. It is as if to say "Hey, we've seen the missing aircraft!" then, well, nothing. The fact that they did say "...and the details have been passed on to Malaysian Airlines" is a responsible thing, given that Malaysian (Or technically it seems, the Malaysian transport minister) is the official mouthpiece. But the fact that after all this, that Malaysian is tight lipped, is incredible. I think of the family members, who must be longing for closure, hearing "We've seen the aircraft", but then NO acknowledgement from Malaysian. I can't imagine how frustrating this is. How about some details? When did you hear from the aircraft? What did you hear? Do you have any position, speed or altitude information? Give us some parameters on the error factors? I mean, give the people something to go on. |
oil rig email
Ramjet
I read earlier on this forum that the email had been shown to be fake. Is that wrong? |
Local Moonset in KL was 00:40am, coinciding with takeoff time. As the aircraft was initially eastbound, it is safe to say the entire flight was conducted in darkness, only stars could have provided some directional info to the initiated. |
BobM2 There is no "speed" input to the transponder. ATC gets groundspeed on the target from their own computer. Airspeed Ground speed Vertical speed Track Bank angle Desired altitude ( yes it rats out what you've dialed in or have in your flight plan) Heading Bout the only thing it doesn't spit out is if the pilot had the turkey on white or the ham on rye for lunch. |
