Passenger interviewed on the radio claims the descent rate as 20,000 ft in less than two minutes - he worked this out from the inflight display.

Seems unlikely but I'm sure it was a frightening experience!

Sounds dramatic, but really. Once the high rate of descent is in place I would not think you could tell in the back that it's anything other than a steep descent. And would the passenger prefer a nice slow descent while they asphyxiate.

Oh and the landing would be normal, albeit early....

Isn't a high rate of descent to a breathable altitude the norm for a decomp?

A jet the size of an A380 can only descend around the 4000fpm so 10000fpm is a bit high as the speed would be far too high.
The relief plane leaves Baku at 7.40am local time and then the repaired plane is due to leave 19hrs after that. The team of engineers are obviously arrived on the relief plane, hopefully with the correct door seal!

The A380 is a big unit, but she can still manoeuvre exceptionally well. In an emergency descent in the simulator it would not be possible to keep 10'ooo fpm continuously, but 6500-7000 fpm is easily achievable.

Not even air France could do that ROD! Once at VNE it would be half that rate Shirley?

Yes but I don't think the airframe of something the size of the A380 could take that rate.

What's wrong with everyone, where's the flying spirit we used to have?

It is just a door seal! descend to safe height, check door, continue to destination, avoid mountains on the way.

More entertaining flight, everyone happy.

Reminds of a flight to the Isle Of Man from Blackpool many years ago. Cant remember what plane i was on however we hit a sever storm not long after leaving Blackpool.

Pilot said he was unable to fly over it so he would have to fly under it.

So he did.

Clearly recall thinking that the sea looked mighty close. Never flew to the Isle again - stayed loyal to Steam Packet Company after that experience!!!

Unfortunately it's not a Cortina where you can slow down, open door and give a good slam and carry on.
I could be wrong but they would not have enough fuel to continue at around 10000 feet and the door sealing and fit is a highly specialised area.
See attached pic of seal and damaged window, I would say it is serious enough to divert but no real imminent danger. The masks deployed because the leak was bad enough and the compressors couldn't keep up.
I think maybe the crew should have been a little more informative but I have not heard what was said over the intercom.

Concerning decent rates:

Im an ATCO working in the upper airspace.

Ive seen pilots (on numerous occasions) use 5,000+ fpm for no other reasons than sts and giggles.

The 'best' ive seen are a Delta 767, an Air Berlin A330 and a Lufthansa 747 all do 9,999+ fpm (thats when our system displays ++ rather than a discrete rate) purely to meet a prescribed clearance limit!!

Seriously high rates are not attainable for prolonged periods of time, partly because at 10k+ you are on the ground within 4mins even from the highest cruising altitudes hehe

5k fpm for 3-4 mins is not common, but ive seen it enough times not to be surprised.
I was on a Thomas Cook 757 into Luton who apprently got very late clearnce to land. We dropped like a stone and did a very tight turn onto finals. I found it great fun but no one else did hehe.

I see from your profile you got that 'bid'. Going to change your username?

PS - what's it like?

PPS - once managed 10k (only momentarily as it accelerated with full speed brake and AP disconnected) down in a 320 just to see what it could do - Nervous few days after to see if there would be any phone calls/e mails asking for an explanation. whistle

HS-125. Decimal 7 Mach converting to 280kts IAS, IDLE/IDLE/AIRBRAKE would easily give you a sustained 15000fpm wink

Interesting!

I'd almost forgotten about the half Spd brake with AP on the 320.. Happy days smile

Reading the quotes in the news story amaze people. Passengers complaining about a lack of information and provisions, YOU'RE IN fkING AZERBAIJAN! I'm pretty sure none of the crew expected to be there either. What a set of tits.

Is it 100% oxygen in the masks on an aircraft or a more normal atmospheric mix?

Aircraft use individual chemical oxygen generators that last about 20mins, presumably they are 100% O2 but not sure on that.
