fuck ppl are quick to jump to conclusions and are experts in everything.

What does LAME stand for again?

On another note...my uncle is a QANTAS captain who regularly flies that route. Was a little worried when I read first few lines of breaking news today.

He's always gone on about how important seatbelts and actually wearing them on flights are given the dramatic dives and the likes involved in such drama's (and obviously for other safety reasons). Would have been a heck of a ride without one I'd imagine.

As already stated, quite easy to lose massive amounts of height in short periods of time in a "controlled" manner. I've done quite a few emergency descents in the PC-12 -

1. Power to flight idle
2. Oxygen masks on, undercarriage down
3. 20-30 degree nose down
4. Dont exceed max Mach or IAS whatever is the lower.
5. Approx 4000 feet per minute descent
6. Recover from dive.

Recovery completed by 10,000 feet back to normal descent! It sounds pretty full on as the media makes out, but in reality is quite a smooth stress free manoeuvre, maybe a little negative G and some positive G on the pull out.

I would say maybe 2000-3000 feet for a 747 to pull out.

Oh btw i loved it when the news reported that the cabin "de-pressurised without warning".....

"Ladies and Gentleman, this is your cabin speaking, I'm about to blow my seal and lose all that wonderful air pressure thats keeping you alive. Please, don your oxygen masks when they fall from the ceiling, strap in, and enjoy the drop. Thankyou for flying Plummet Air"

oh dear.... im rambling again....

How many people would lose their lunch in a controlled dive ... ?

/general-question

[lethalw]

does going into the sick bag count as a loss, or are we talking all over the person in front of you....!!!

Seriously though i think most feelings of sickness would come more from the anxiousness of the situation more than the loss of height itself...

passenger? unlikely... but possibly something in baggage
baggage crew? maybe the door wasn't locked tightly... but i'm sure there is electronics to warn against stupidity


if i had to put money on it, i'd say engineers and maintenance

plummeting 20,000 ft would scare the SHIT outa anyone!!!! specially not being in control!!

Its not likely the engineer or maintainence staff, they are the end of the chain.

The problem with quality is from the manager level, people who put the perception of productivity over quality, people who only focus only on number and profit margin. Once that perception set in place, engineer and other staff have no other choice but follow.

Funny that people trying to archieve productivity by compromising quality, while the real answer for higher productivity is by improve quality.

Quickest way to have your aircraft not start, the GPS installed upside down, or a sudden smoko when you need something signed off!!

I'd be most pissed off about the luggage loss.

"I'm looking at the plane now and on the left hand side, just forward of the wing, there's a gaping hole from the wing to the underbody.

Passenger obviously cannot tell left from right......

[cruelcheffy]

I think it is about time to retire the 747's. I work for that mob too and see a lot of them delayed due to problems.
On the other hand I think credit is due to the crew that brought that bird safely to the ground!
In times like these decisions have to be made to rationalise, and sometimes they hurt people. In Years to come when other airlines may be gone due to financial difficulties Qantas will still be here (hell, I hope).
Also, they have just been voted one of the 4 safest airlines in the world people would fly with.
Also, most of the "sackings" were in overseas offices and among air crew. The engineers have come to an agreement withe Qantas.

LOL, it would probably be in singlish... ,"Radies and Gentlemen, this is cabin speaking, oke lah. I'm about to blow my seal LAH.."

I don't know how many would lose their lunch, but I think it'd go a little something like this....

That's a golden clip, that one.

[thro]

So rather than a 20,000 ft drop, we're talking about a 4-5 minute descent, at 4000ft/min.


If anything, imho this highlights just how safe aviation really is.

The aircraft would have been doing 900-1000km/h and lost structural integrity (design fault, maintenance oversight, whatever the reason was *shrug*).

It then proceeded to descend in a controlled manner and made an emergency landing at the nearest airport with zero loss of life. (not even any injuries).



But that doesn't sound quite so sensational as "plane explodes and drops 20,000ft now, does it".

fuck ppl are quick to jump to conclusions and are experts in everything.

FIRSTLY

can i just point out that i wasn't jumping to any conclusions... nor do consider myself an expert in the field.

I was just highlighting some of the causes that i "THOUGHT" would come into play.

SECONDLY

if a fabricated part was installed with a fault... would it not be the engineers or maintenance crews JOBS to pick that fault up??

THIRDLY

i wasn't pointing blame to the maintenance/engineering crew... (who am i to do that anyway?) i was actually agreeing with someone elses previous comments that its because of CUTBACKS that proper maintenance of these aircraft cannot be done.... (although i must admit the way i put that across was very poor, and subject to misinterpretation)

...

and while i'm at it, thanks lethalw for sharing the decompression dive procedure for a pressurized aircraft. Very interesting. IE. 4000feet/min.

The best plane I've ever flown is a Mooney, and therefore didn't get to learn that stuff.

[TORQ]

I went out to the airport.

My llama wasn't onboard.

Oh ... dear.

If anyone sees it, please PM ?

[sucka]

Your llama has flown qantas before (knows the risks)

GOLD...rep given....the bad part is, these are real issues written down by the pilots...
