If therr was a fire it may have started in the ELT.

You don't need pressurized oxygen to stay alive that is saying the pilots need pressurized oxygen to have no oxygen starvation and no hypoxia at all and not be impared to fly the aircraft.

As it says you can breathe 100% oxygen not pressurized at 40,000ft and that is like 10,000ft of altitude which won't kill you.

I think you may be misreading it, the 10,000' at 40,000' analogy is if the pressure hull has not been breached and is what you would feel inside the aircraft. A depressurized aircraft at any altitude is going to experience that altitude internally. The pilots do have pressurized oxygen systems and any depressurization at cruising altitudes and above would require the pilots to have that system to remain functional for any amount of time.

That is not correct.
That data transmits separate of the ACARS I think they said 1 time per hour.
The software package they could have paid to subscribe to also would have transmitted independent of ACARS and would have been monitoring numerous items.

I was under the impression the B777 had two, one fore, one aft. Are they harnessed together? Could a fire disable both?

The one hour was the keep alive pings for the data service from the satellite. ACARS would have gone out over that system had ACARS been working. No data was sent - there was only the sat checking with the plane.

The other package was a Boeing product. I posted that days back.

At least this is what my researching has discovered,

edit:

The rolls-royce data that had came from ACARS.

To fight an electrical fire they shut down the bus. This would include the ELTs.

I was just looking for the exact explanation of those separate of our MSM experts. The way they explained this looks like it was wrong. They tried to explain it like the engine data was separate of ACARS, which it isn't, and that the subscribed service was also separate, also incorrect.

They also have repeatedly made it appear that the pings they got hourly were from the engine data when actually they were from the SATCOM system.

I stand corrected. Kudos....

Well, that's our news people. Instead of digging into how things work they build fancy props to walk around on and draw lines with light using their finger. Too many people want to see something 'cool' instead of listening to words that require thought on a subject to understand it.

Glad you don't fall for it.

Right, I beleive you said that earlier or in one of the other threads. It is getting hard to keep up with all the topics. Apologies.

No worries. I'm barely keeping up myself.

Zap, by ELT, is that the location beacon? I thought those were made to deploy on force due to crash on land or water. What am I misunderstanding?

I keep hearing that the "alright goodnight" is unusual for the signoff on the news. Has any info been released on if the co-pilot who said it has said it before, as in maybe his usual signoff? I don't find it that odd to say if you are switching over to a new region, but I am not a pilot. Is it possible the controller said goodnight and he was just answering? Not sure why this keeps coming up in the news.

They are supposed to. If it ditched in the southern Indian Ocean, we they are searching now, they would have deployed upon impact unless they were destroyed on impact or disabled prior to. The crash also occured over ten days ago and I believe, according to a manufacturer, they last only 48 hours.

Pilots ALWAYS say "have a good day" or "see you in a few days", etc when handed off. If you listen to liveatc.net you always hear it.

Hearing controllers and pilots say 'good night' or 'have a good day' is not unusual, at least not in the states. (from what I hear listening to the radio traffic)

Power can be disabled to them, by fire or pulling the breaker. We had to do that on a -135 after it popped three ELTs due to a bad shock sensor.

Just listened to Kuala Lumpur tower for a few minutes. The tower and planes were using good morning quite a bit. A 'good night' leaving the air space is probably very common.

Reportedly the cargo included lithium batteries.

Okay, Thanks. That's what I wasn't understanding because at least two of the engineers stated that if the plane crashed the beacon would have been heard immediately by "other traffic" in the area. Two of the pilots were saying similar things and were convinced that the plane hadn't crashed because there was no mention of emergency. They seemed convinced that the plane flew somewhere and landed safely.
But if there was a fire what would prevent them from signaling that in some manner? That is what is so confusing to me---no mayday at all.
As I said earlier, maybe I'm just trying to hope for the best for all those folks on the plane.
Sorry for the questions but I'm having trouble keeping up with all the threads on this and I refuse to listen/watch all the airheads on msm.

An electrical fire would require pulling the power bus and slowly restoring power once it is out. Depending on where the fire was it could knock out coms, and transponder. Or if a cockpit fire take them and the crew out.
