CX882 Diverted 11/15/2012

Anyone have any idea what happened? I had two friends on that flight and they're in Alaska. Apparently the plane depressurized and descended, and they landed in Anchorage.

It left HKG at 4:35PM HKG and was due to arrive LAX at 1:05PM 11/15.

Crazy stuff...hope everyone's OK - physically, at least - that would have scared the crap out of me. The picture I saw showed all the masks down and a mostly empty plane.

I just saw the info from flightaware when I was checking on-time performances for HKG-SFO/LAX flights. It's terrible and Cathy needs to check its fleet carefully as such incidents are not rare on it.

Um, which other "incidents" did you have in mind? I haven't checked any data (and I suspect neither have you), but my impression is that to the extent this happens on CX, it's no more frequent than with other world-class carriers.

I was scheduled on the return 881 in J just after midnight tonight. While I was on line checking in for my LAS-LAX portion CX called and said the flight was rescheduled for Friday afternoon at 14:40, and they would send a rep to meet me at the gate in LAX. They said they would be paying for a hotel there. I'm also missing my connecting flight in HKG so they'll be paying for another hotel in HKG for a night.

So yeah it's gearing up to be a very long trip home.

Interesting flight path: the aircraft made quite a sharp right turn toward Anchorage, apparently suddenly going directly north when the decision was made to divert.

Depressurization is one of the worst thing that can happened to the plane. People can literally died from lack of oxygen in a matter of minutes, and the mask only provides oxygen for up to 15 minutes at most. This is why it's not fine to say "it only happens once awhile compared to other world-class carriers", this type of incident shouldn't happen at all with today's modern advancements and CX's reputation of being extra careful in maintenance.

CX882 Diverted 11/15/2012

Before we descend further into hyperbole, how many depressurization incidents have there been in, say, the past five years? How many people have died in them?

The 15 mins thing is true but irrelevant. The masks aren't intended to last until the plane lands. Rather, they ensure survivability until the plane descends to an altitude where the air is breathable. The plane can then fly at that altitude until it reaches the diversion airport. Apparently it works, since there don't seem to d many reports of pax dying on the rare occasions when this does happen.

Not saying this is not a significant problem when it happens-which is rarely. But the fact-free hyperventilating around here is really remarkable.

For example:
A CX LHR-HKG flight's emergency landing in Moscow last X'mas:

and more earlier:

CX363, in Shanghai Pu Dong, emergency evacuation:

CX882 Diverted 11/15/2012

Divide these three instances of mechanical problems in flight by the total number of flights CX has operated in that span and you'll realize the percentage is infinitesimally small. And probably compares favorably with other major carriers.

As frequent travelers we all have an interest in safety. But let's lay off the unwarranted panic.

to name a few

http://avherald.com/h?article=4503f885&opt=0
Incident: Cathay B744 near Frankfurt on May 16th 2012, cabin did not pressurize

http://avherald.com/h?article=436ae631&opt=0
Incident: Cathay B744 at San Francisco on Jan 23rd 2011, could not pressurize cabin

http://avherald.com/h?article=433fd09d&opt=0
Incident: Cathay Pacific B744 near Karaganda on Nov 28th 2010, loss of cabin pressure

http://avherald.com/h?article=430c777d&opt=0
Incident: Cathay B744 near London on Sep 11th 2010, cabin pressure problem

http://avherald.com/h?article=43054420&opt=0
Cathay A333 near Taipei on Sep 14th 2008, loss of cabin pressure

More interesting one is the findings in the 2008 report. Let's say I hope they have trained the cabin crew better by now

Is that even a 0.1% incidence rate?

Hmm it seems to be pattern with CX. However, the fact that none of these incidents turned into major disasters is also testament to how great their flight crew is. You know you're in good hands when you fly on CX.

Would you mind digging out the records of JL and other top airlines. Interested to see whether this is specific to CX?

did you read the 2008 incident report? More specifically

Quote:
12. Some cabin crew members whose oxygen mask did not drop down, did not try to open their access panels or using portable oxygen bottle around their seats. (2.9)
13. Some cabin crew members may not be familiar with the cabin masks design features and operation with regard to pulling down on the cord to activate oxygen flow and not be fully aware of the normal operation of the cabin masks. (2.9)
14. Some cabin crew members who were not to or not able to use their oxygen masks may have misled passengers into thinking that wearing the mask was not required. (2.9)
There are parts which are related to the flight crew too but I found the cabin crew part more surprising. I hope they have learned from the 2008 report and this wasn't the case for CX882 incident.

nevermind, anything you digged up will be dismissed as "small percentage", "no one died", etc.
