Malaysian airlines has lost a 777

[skyking]

Regarding the ability to turn off/on the transponder:
pretty much any radio can get nuked by a power surge, and start to add tasty smoke to the cockpit. Nice to have a power switch and breakers to pull. I have never had a fire like that but a friend of ours did, and I spent many hours working on the plane to get all the toasted electronics out. The alternator went to 90+ volts and all the breakers fused and melted. The juice just kept on keeping on.
He had a couple of first time passengers on board 😀

Even 9/11, it took a while to find the box, but they knew where it was, generally speaking.

Uh, on 9/11 no black box was found, unless you are referring to the Penatagon and the Shanksville Pennsylvania crash.

I don't know - I'm sure there may have been times that they had to be shut down for precautionary measures.

Found this (quickly) so maybe??

No safety concern from the transponder.

The counterpoint to this is why we have to shut off our phones on take off and landing. Everything is based on FUD mostly. The real reason for electronics is so everyone is paying attention on take off and landing, but in reality they'd be more attentive fucking with their phone.

Unless of course that GPS inside it could compromise things at times.

I am sure your planes are subject to cellular issues.

I don't think a 777-300 operates the same way bro.

I have heard a lot of private plane talk since where I used to live had a private airport for the homeowners there.

Educate me.......

First, have you been to college? If so, were they even in the top 100? What major?

If you don't know a real answer, to a pretty fucked up topic you are replying too (I think this should be in P&N or Discussion Club to prevent full on trolling, but things are getting lax here and non-biased), you should probably just zip it.

 

[skyking]

read my post, alk. It mentions why you want to be able to turn off the transponder. It had nothing to do with cellphones.

I thought I remember them finding the black boxes. I don't imagine they would have been in very good condition though. But maybe it was the Pentagon only that I remember.

humm people in the Maldives calim to see a low flying jet at round 6:30am that had marking matching Malaysia airlines.

Looks like I was pretty close over 4 days ago

If the plane continued west towards samalia there are 2 small islands in the Indian Ocean that have airports. Could it be possible that they landed there and nobody has said anything?? (highly unlikely). The first one is only 4000 feet long so its unlikely that it could land there but the second is 10,000 and very capable of putting a 777 down.

Thats probably the max of the range of its last reported position at 2 am. Looking at the map it could have crossed into India (towards Iran) but I'm sure they would have detected that on radar. It could have made a turn south and hugged the western coast of Australia too (although that would be stretching it).

Your feedback is not equal to these kinds of planes.

It's like the roaming carnival worker speaking about their patch work to Disney parks.

 

[crashtech]

N/M, reading disappoint's answer cleared that up. I knew that the 15 NM is in any direction, so if it's >15 NM deep then obviously the signal wouldn't reach the surface. I just haven't checked to see how deep the indian ocean is........

Edit: Just checked, at it's deepest point Google says the Indian Ocean is 4.34 NM deep. Is there something about the water that impedes the signal?

If you read up on the way submarines communicate, you'll learn more about the difficulty of propagating a radio signal through the ocean. There are powerful land-based ELF transmitters that enable one-way communication to the submarine, but transmitting out is another matter entirely.

 

[rudder]

Not an expert, so just more questions for me.

What are the chances that an electrical fire causes complete communication blackout, but that the airplane itself flies perfectly fine with autopilot for a few hours until fuel runs out?

Heck, if the pilots detect an emergency, wouldn't they have tried a last ditch attempt at landing before being completely incapacitated? I know things can all happen very quickly, but you'd think at least they would have disengaged the autopilot and tried something?

Chances are extremely slim. The 777 has backup systems for its backup system, along with an impeccable safety record.

Look at the valuejet crash in the Florida Everglades. Within two minutes of taking off the plane burnt itself up and crashed into the Everglades at 800mph. But there was still time for the pilots to tell ATC that something was wrong.

There's no education in that, just questions. What have I posted that was wrong, besides the black box thing? I was wrong about the black box sending radio signals underwater, and yes, I feel kinda dumb over that. I'm guessing that what I read that mentioned 15 NM was referencing the sonar signal that the black box is capable of sending, if in fact it can. Nothing I've said has been presented as fact however, it's all in the course of a discussion. If I were speaking to the family member of somebody on this plane, you better believe I wouldn't say a damn word unless I was positive of what I'm saying. On a message board, I'm just talking with people. Nothing I've said is any more far fetched than half the other people here talking about their theories on where the plane went. I have not presented myself as having any special knowledge or expertise. Besides, the way you write things, I can't tell what side of an issue you come down on most of the time, anyway.

I will do that. Thank you.

 

[rudder]

I think it's more like 7 days. They also have to get close enough to it. ex: it's it's own transmitter, it's not actually talking with a satellite. At least I think that's how it works. In most crashes the plane is found before the black box. This is a unique (somewhat) case since the whole plane can't be found and it's location is completely unknown.

Even 9/11, it took a while to find the box, but they knew where it was, generally speaking.

Unless the plane crashed and the black box experienced a certain amount of g's...it won't transmit a signal. Another way to activate is if it get submerged.

 

[TangoJuliet]

The article seems to indicate that the programming occurred before 1:07, because it goes on to say that they know about it from an ACARS transmission. I have to assume that they're referring to the 1:07 transmission, as the 1:37 one was scheduled but never occurred.

So, assuming all of this is true, you can't reconcile that with the "all right, good night" at 1:19 in the absence of foul play.

So I guess its now been confirmed that the original flight plan was changed in the FMS and that change was transmitted by ACARS at 1:07 am. Since ACARS transmits that info in 30 minute intervals the previous transmission would have been at 12:37 am which would be when the plane pushed back from the gate or was taxiing to the active runway. I would be curious if that transmission at 12:37 had the change in it as well.

If there was no route change in the 12:37 transmission then the change was probably made shortly after takeoff.

You still didn't read or understand my post, and you know fuckall about aviation, compared to me or anybody else with background.

Don't try to make this a popularity contest bro or you are just contributing.


I don't know fuckall about aviation. I have known more than a handful of people that own their own planes and helicopters and one that owned a real jet.

I like to talk to people, I have learned quite a bit talking to them and their crews when applicable.

I really don't think something like the Blackbox or Transponder should be turned off ever. If they become fire hazards one should be able to rip them out and smother them.

On a commercial aircraft I personally see the value of knowing where the blackbox and transponder are at all times is a valuable thing.

 

[TangoJuliet]

No safety concern from the transponder.

The counterpoint to this is why we have to shut off our phones on take off and landing. Everything is based on FUD mostly. The real reason for electronics is so everyone is paying attention on take off and landing, but in reality they'd be more attentive fucking with their phone.

Unless of course that GPS inside it could compromise things at times.

I dont understand what you are trying to get at? Just because there hasn't been an accident/crash because of a fire started by a faulty transponder doesn't mean it hasn't happened or avoided by shutting it down.

Pilots want to be able to have control over everything in the air. Unlike a car, you just can't pull off to the side of the road and get out. It could take 30 minutes or more for a plane to get back on the ground.

I'm not an accident investigator but I do have a pretty advanced background - would you like my credentials?

I no people with plains and I no more then everybuddy hear. Courtney Love called me to help her investagate this mistery.
It will be solved by morning.

I agree, it's because I am honest. People today want agreement with their stupidity. If you are going to post on a major world event, please have some knowledge first instead of spreading FUD. To help you, that's Fear, Uncertainty and Doubt. I don't see you as the seeder (it's a powerful tool), you just somehow bought into it.

"Hey I showed up for the bestest job I ever could have got! I forgot to take out my face piercings and was only a little late and only a little hungover/stoned 🙁...that bastard told me to leave the building! It was a sure thing! OMG I have been so much more stoned than that in my life! These manager people probably never worked a day in their life!"

I am hoping your 02Ranger <> you were an actual ranger in the military.

You have a lot to offer. Why the fuck aren't you in Malaysia getting this thing sorted out?

 

[fjmeat]

plane is in Pakistan at a Taliban controlled airfield. US called off the USS Kidd naval search. More to come in 24-48hrs per US intelligence. Delay is issued not to embarrass other countries in the search. US has very strong leads the plan has landed in Pakistan. No word on the passengers.

The real reason for the cell phone ban is so that you're not stuck next to some idiot jabbering away on his phone for 5 hours straight. Can you imagine being stuck on a flight with the person on your left and the person on your right talking nonstop while fighting over an armrest with you? The heart of the rule is forced common courtesy, not technical issues.
