BREAKING NEWS: Press conference on #QZ8501 expected at 12 am ET.

a reply to: Bigburgh

Way too early to tell. There was some kind of weather in the area though if they did request a descent because of tutbulence.

Airbus did have a problem with Thales pitot tubes freezing in bad weather, leading to bad data, and some close calls, but they were all supposed to be replaced already.

WHAT!
Then you found the first Malaysian airliner?

a reply to: southbeach

And what do you think happens when they crash, until they're found? I'd call that "missing".

Indonesia media reporting @AirAsia #QZ8501 passenger nationalities:
149 Indonesia,
3 Korea,
and 1 each from Singapore, Malaysia and UK.

If not mistaken.. also a stress fracture issue. Making turbulence a bad thing to encounter.
Boeing too.
Agreed that its to soon.

Just heard the news. Wow--I can't (well, actually I can, unfortunately) believe that ANOTHER ONE went 'missing'.

Well, before I start assuming things, maybe the officials this time will show a little bit of rare INTEGRITY and fess up the TRUTH as to what went down.

Better yet, I hope that they find the plane and people alive and well. Maybe a radar glitch. If only. :/

This despite what Zaphod, who is an expert in these matters, had said about radar coverage?

Here is the thing. From what I understand of the make up of the tracking systems for aircraft, you have two main ways that an aircraft gets tracked through airspace. Over land and coastline, there is radar coverage, and that directly tracks the object of the aircraft itself. Then you have the reporting systems aboard the aircraft, radio links with the mainland of whatever air traffic control centre is nearest to the aircraft.

There is NOT any way for a satellite to track every aircrafts physical position, without the aircraft reporting it. It is just not possible. Unless you had one satellite for every aircraft in the air, all dedicated to doing NOTHING but tracking that one aircraft, there would be no way to do it. So contrary to your belief that nothing happens on the face of the Earth that goes unnoticed, actually, any plane that spends a significant amount of time over open sea is basically like Schrödinger's cat, until it gets into radar range of land based systems again, and their range is limited, very limited indeed.

Just think, if everyone on that plane was chipped?

Hopefully that's it. Good find!

Then every plane that is made hence forward.
Needs A.W.A.C. ability.
It's the only way I can think to cover miles of airspace!

Eventually they'll have the ADS-B system fully integrated for over water flights, but for a few more years you're just about spot on.

There are two radar types over land. Primary and Secondary. All Primary antennas have a Secondary antenna, but a Secondary only system doesn't need a Primary antenna.

Primary sets track based on the radar bouncing off the object. This gives fairly limited data as far as altitude and airspeed, and no data on identity. That's where Secondary comes in. Secondary relies ONLY on the transponder signal. So a Primary set will have a Secondary antenna attached to get that data. That's why when the transponder is turned off some radar systems don't see anything anymore.

Yay! Found maybe?
Boo! People lost their lives!

a reply to: opethPA

that's just north-west of where they went missing. I hope though that it didn't crash or if it did - there are survivors.

Read reports from Twitter, not verified but crew ask for unusual route before losing contact, why?

Why is right, didn't control ask? Or did they get cut off before they could answer?

According to the CAAS, they were scheduled to arrive at 0830 local. The Singapore Navy and two C-130s are on standby to assist if requested.

a reply to: Bigburgh

Imho it's much better than them never being found. Also if it is the craft, maybe if they find the cause and it's mechanical they can help prevent it in the future.

Or if it's terrorists I wont' get into it

I'm very sad they have crashed and I hope each pax is accounted for
