Missing 777

[yelbike]

This time line has a significant variation from the one you are referring to. According to CBS, the significant change in course happened 2 minutes after the sign off. The transponder stop transmitting after the pilot said "all right good night".

Just add to the confusion. I read this morning the "new" flight coordinates were entered two minutes prior to the good night sign off but turn was initiated a short time there after.

So the fire theory only partially fits. Imo

Had to do some more research to clarify what I thought I had heard. I guess it might be "sort of" flyable with a computer failure.

11.5.2 Mechanical Control
Spoiler panel 4 and 11 and the alternate stabilizer pitch trim system are controlled mechanically rather
than electrically.

question about 777 flight controls [Archive] - PPRuNe Forums

Part of post 1:
I was wondering if the 777 fbw controls allow for manual reversion.

Part of post 2:
The above modes still require electric power. When it is not available, the mechanical backup you refer to is used to control the plane.

It consists of cables from the flight deck to selected spoilers, and the stabilizer. As far as I know, there are no cables to the rudders.

Part of post 8:
The only control surfaces mechanically connected to the flight deck on a 777 are a pair of flight spoilers and the horizotal stab trim system.

Yes, I read about 4 & 11. You can't fly that airplane with 4 & 11. Its the equivalent of putting your hand up into the air when riding a motorcycle, or dangling your hand in the water when gliding in a canoe.

That's what I was reading as well. The turn happened after the "good night". Anyhow, the post you linked to is plausible and probably best explanation I've heard so far if there was no criminal intent by anyone. Good find. :thumbsup:

While the turn happened AFTER the 1:19AM "Good night", it was programmed into the Flight Management System BEFORE 1:07AM (the time of the last "Call Home" from the Flight Management System). If they were having an issue and decided at 1:07AM to change course, why didn't they say something on the radio before they signed off with the Malaysian ATC 12+ minutes later (at 1:19AM)?

I misunderstood the timeline earlier and mixed up the actual turn with when it was programmed into the system. As described in your link (starting at ~0:28), the change in course was programmed into the Flight Management System before 1:07AM, well before the 1:19AM signoff with the Malaysian ATC.

It may have just been a good habit to put other coordinates in as you go along in case something happens. I don't know. When I drive in South Bend at night, I always look for escape routes at stop lights, curbs I can jump, trees I can slip through, etc... in case of car jackings. (I know that's sad, but that's life in this hades-hole :laughing. And I have heard and read that it was programmed into the computer ahead of time, but I was never clear how anyone knows the time it was programmed in. Was that transmitted to the airline before communications died?

 

[MossRoad]

Ahh, the flight management system. Thanks.

The cartoon pretty sums it up. I have never heard so many "experts" that don't even seem to know how to answer the questions supposedly in their field, let alone any questions that drifted out of their scope. Where do they get these people? Just grab mooks off of the street?

 

[MossRoad]

Don't disparage the mooks. :laughing:

Any chance the Australian search was a decoy while MH370 a activity was going on in Pakistan? They are still cranky with the US after that raid that picked up Bin Laden.

I'm not sure if we're talking about a computerized system or someone jotting entries in a paper log at this facility on the other side of the world. Is there any chance that someone on the ground fudged the 'good night sign off' because they messed up and didn't do a proper sign off? ie, they nodded off and fabricated the signoff and/or timing. Maybe a software bug recorded the wrong time or the computer hadn't done a proper time sync and was off by several minutes?

How's that saying go.. oh yea, "Never attribute to malice that which is adequately explained by stupidity"

In this case, there is a computer navigation system (similar to GPS) which "calls home" every so often. Someone entered a new waypoint in that system before its final transmission 1:07AM. They have compared the signoff (made at 1:19AM) to the voices of the pilot and co-pilot and it is said to have been the co-pilot.
If they were having problems with the plane that required a new course, they would have communicated this before the signoff. ~2 minutes after the signoff, the transponder shut off and given how far out they were, they dropped off radar, until they were picked up by military radar around 2AM.

Yea. I'm questioning the validity of the timestamp of the signoff. E.g., it really happened at 1:05AM and the wrong time was recorded somehow. Maybe someone at the airport has a habit of doing that, but this time the plane crashed. That seems a much simpler explanation than someone stole a plane full of people. I just don't know if its feasible for someone to falsify a timestamp, or possibly an issue in the control tower that caused the wrong timestamp to be recorded (software bug, bad time sync, etc).

Plausible perhaps.....but it shares one glaring impropriety with the black hole, AWACS abduction, alien abduction and every other theory.
There is no plane and no plane wreckage.

This important fact makes all of the "conspiracy theories" worth reading.

Flt 370 had a large cargo of lithium ion batteries. Well, there you go. HS

The co-pilot was heard mumbling on the radio.
