Air Asia returns to Perth

[JohnMcGhie]

So: What was wrong with it?

Now we are all agreed that passengers are full of it, and their airline maybe not universally approved of, has anyone had time to find out what was "wrong" with the aircraft?

Enquiring minds...

[wongsuzie]

Indo or Malaysian CC.

"Get down" translate as sit down.

[mr did]

Another Indonesian LCC incident, is anyone actually surprised apart from the dumb asses who paid $10 instead of a proper airfare to cover the actual cost of operating a well maintained and operated aircraft.

At least this one didn't end up in the water...

......has anyone had time to find out what was "wrong" with the aircraft?

Why let facts ruin a good story ?

It actually can for a second... might not seem much but enough to catch you off guard especially if your hands are full and conditions aren't smooth.

I only know because I've experienced it first hand on a steep descent (wasn't even an emergency descent) I was down the back, flight had been a little rough due to the hot weather and when the descent began all four of us who were in that spot lifted off the floor for a fraction of a second.

You guys up the front don't feel it the same as people standing up down the back.

(1) Interesting. Why not? Intuitively I'd have expected a few moments of low G in a quick transition from cruise to steep descent. Do the Airbus electronics manage the descent in such a way as to prevent "weightlesness"?

(2) Is it different on non-Airbus types?

[TURIN]

I thought in an emergency descent the a/c always maintained positive G by rolling/pulling over.

I watched a tv program about the UKs RAE and they showed the manoeuvre using a BAC 1-11.


I am not a pilot.

O2 flow is easy to sense.....

It's easy to tell if the O2 is flowing: If you're conscious, it's flowing!

Cabin crew announcement recording discovered

Audio quality isn't great, but you can definitely hear "get down"

Anyone see the video where someone was wearing the mask just over their mouth (and chin) rather than over the nose and mouth?

My former airline had an automatic PA decompression announcement which instructed passengers on how to wear their masks (i.e. "pull down the mask and put over your nose and mouth and breathe normally").

Having said that, I've only heard these announcements in one language, so there may have been language problems.

What you can't see is who she is screaming it at or why.
Maybe she was screaming at three passengers who were trying to get their hand carry out of the overhead bins? Couldn't happen? Don't be so sure.

I dunno, if you're computer literate enough to upload a video to youtube I'm pretty sure you've also seen numerous movies where people on a plane don masks.

he was just too eager to be the first on Instahogram to upload it to put his mask on properly...

Totally agree with Wingnut. Most likely the 'get down' was aimed at someone too stupid to sit down

[givemewings]

can the mask be worn with the pin still in the generator?

Yes it can, but it'd be just for decoration.

Maybe if people actually PAID ATTENTION to the safety video they'd know how to use it?

I know, too much to ask.

[WingNut60]

I do think however that it is frequently the case that not enough emphasis or explanation is given to the need and method to start the O2 flow, or the consequences of not doing it correctly.
Mind you, useful information for some, blah blah blah for others.

[Centaurus]

I thought in an emergency descent the a/c always maintained positive G by rolling/pulling over.

To start a rapid (emergency) descent there is no need to roll/pull over. In fact that is a good way to find yourself in an inadvertent unusual attitude which could be fatal if at night or in IMC at that high altitude. Today's airline pilots may be experts on watching or monitoring the automatics fly their aircraft, but probably not crash (joke, Joyce) hot at manually flying at high altitude. If they start rolling and pulling while flying manually at high altitude, you can just about guarantee a handling problem which leads to a more serious flight safety event

A gentle push-over straight ahead is all that is needed to start the rapid descent. There may be local ATC rules that require the aircraft to be turned off the air route before starting the emergency descent but not everywhere around the world.

[KingAir1978]

An airplane in flight will ALWAYS rotate around its centre of gravity. Therefore if you push the nose down, the tail will experience a temporary INCREASE in 'local' g... in the front, however, you'll experience a temporary reduction in g-force. All modern airbusses are protected. They won't allow you to go beyond -1 and +2.5 g in clean configuration.

This is way off topic, does anyone know what the matter was with the airplane...

How many passengers passed out through lack of oxygen?

[WingNut60]

I have no idea. And I'm not sure what you are inferring.
But then, I'm not sure of the real nature of the problem or the extent of the depressurisation, if at all. The descent seems to have been quite leisurely after the first 30 secs of oh-

How many passengers complained of bleeding ears? Don't know that either.

But I do know that there were complaints of the system not working properly which suggests that:

a) the system was not working properly, or
b) those complaining didn't know what was going on.

I also know that for the non-technically minded (most passengers?), telling them to "pull down sharply and breath normally" may not be enough.
Even the bit about the bag appearing to not inflate seems to be optional these days.
I just think that a little more explanation might help; to allay fears if nothing else. Another 10 secs worth of blurb, that's all.

[G-CPTN]

I was suggesting that, if the passengers did not actuate the oxygen masks then there might have been 'casualties' due to lack of oxygen.
