Air Asia Black Box info

[AdamZ]

Reports say Air Asia climbed at 6000 fpm then stalled. I would not think that a commercial jet could climb at that rate absent being caught in some serious updraft in a very close to mature TS. Be interested to hear what the guys flying commercial jets have to say.

Please note that the alleged climb rate is NOT from the flight recorder:

"radar data showed the Airbus A320-200 appeared at one point to be climbing at a rate of 6,000 feet...."

Nothing has been released yet on the flight recorder data.

That's just 100 fps. I could see a climb (read severe turbulence) of that magnitude lasting a couple of seconds. If you did the math on the g loads it would likely help explain the apparent subsequent failure of the airframe.

I say "failure of the airframe" based on reports of the distance between major parts located.

It's all speculation , YMMV, etc.

There was a report that one out of the first seven bodies recovered was wearing a life jacket. That suggests time enough to make preparations. It doesn't seem consistent with a sudden major airframe failure in flight, though it doesn't exclude other in-flight damage.

I noticed that the authorities say a preliminary report due the ICAO will NOT be made public:
