Qantas A380 in Perth emergency landing

Qantas A380 in Perth emergency landing

the Airbus A380-800 was put into an emergency descent while travelling at some 12,000 metres, eventually levelling out at about 2700 metres, in order to maintain internal air pressure.
Nothing to worry about folks, Joycie's "fix on fail" strategy working as designed.

Qantas A380 in Perth emergency landing

Landing wasn't an emergency landing. Emergency descent, granted, but nothing forcing them to land before hitting minimum fuel.

Standard tabloid journalism strikes headline writing again, bad thread title.

Ok fair enough but it's not just running low on fuel that cause an emergency is it.
In fact in a Fire too much fuel on landing could be a bad thing!! Anyway I digress...

The ONLY time you can have too much fuel is when you're on fire!

Hey, Parliament is out and it's a slack time for the media.

Air conditioning is optional, after all, it's minus 60 degrees outside, how cold do you want to be?

It's just those bloody selfish pax who want to be able to breathe air containing just a little oxygen and can't go without for even fifteen minutes that create all this bad press.

Never mind - we'll cancel the papers so nobody knows!

Now, have we giftwrapped the iPads for the Chairmans Clubs Christmas Tree?

humans love minus 50, they also love a lack of pressurisation.

That Andrew McGinnes guy is right on the ball eh? I suspect he was talking to a beancounter before he gave the interview, not an engineer.

Flying depressurized at 10,000' with no Packs isn't good for equipment cooling.
Things start to heat up....

Got to wonder what would cause a total failure like this?

What happened to the other/redundant systems?

The pax O2 system didn't do its endearing jack-in-the-box thing for passenger amusement, suggesting either a very air tight fuselage or, more likely, a descent performed while the crew was trying to regain control of the cabin pressure systems after a failure.

Clearly the cabin equivalent altitude never exceeded 14,000', or whatever the 380's pax O2 auto deploy trigger value is.

You must have a crystal ball that tells you you're not going to catch fire - when you load all that extra fuel.

Crystal Ball v.2.0 comes as part of the standard avionics suite in new-technology, low-maintenance, fuel efficient, self-maintaining, self-repairing aircraft, doesn't it?

So would it be normal practice to wait til you have reached your emergency landing airport before you start circling and dumping fuel, or should they have started dumping it 700 klms out so they could have landed immediately they got to Perth?

Pretty sure an A380 scheduled DXB-SYD with planned fuel for the trip but then making an unscheduled tech stop in PER isn't going to need to dump a drop of fuel.

VH-CHEER UP--- not necessary so, it may have still been above MLW but I would suggest not by much?

On the 77W there is a 100 tonne split between MTOW and MLW and takes about 12 hours to get down to MLW......not sure about the Dugong.

From their 'news' web site today:

Qantas plane plunges 30,000ft after air conditioning fails



They really are a bloody lost cause ....!

It would almost certainly have been above MLW on arrival in Perth..
The average Landing weight on a DXB-SYD is about 365-365T and with a fairly ordinary forecast for Sydney this morning the additional fuel would have taken that comfortably 370+. MLW is 391T, so with 3 or 4 hours to run it would have been about 400T at least....However Airbus allow landings above MLW in certain circumstances provided there's enough runway. This would qualify.

Just as well the works on 03/21 have been completed on time.....
