This ain't a contrail, those begin much farther away from the engine, the case that the gear is lowered also makes me suspect that it's a fuel dump. I have no Idea where the fuel-dump valve is located on the A380, but right over the engine outlet is a rather odd place.

I must admit Mario i thought it might be a fuel dump,and it probably is,but what a place to put the valve.lol.

Why would she dump over land, as well? This seems to be quite bizarre to me, but then again, I don't know much, haha.

You may want to throw this thread over to Tech/Ops.

Probably testing the nozzels one at a time to make sure they all work before trying the entire system as one.

Judging by the altitude that this plane appears to be flying (probably over 5,000 ft).. by the time the fuel would reach the ground, it would have dispersed into vapour.

Looks to me like a simple test of something..

Perhaps someone working @ Airbus can elaborate?

I could have sworn that was a 747-400, but then after a closer look, it is an Airbus.

But honestly it looks like a 747....

Standard practice as long as you're high enough.

It doesn't. The wing is too broad and a bit too far forward to be a 747.
Fuselage seems too wide as well.
Landing gear is down and gear configuration is quite different from a 747.

Why start a second thread on exactly the same photo/subject?

380 Engine.Is This A Fuel Dump Or Another Test (by Relic Apr 25 2007 in Tech Ops)

Personally I feel it's just an engine problem. Looks too much like burning engine oil. No too difficult to imagine with a new engine type. Could be a labyrinth seal, bearing scavenge pump, oil line seal, partially plugged breather, etc......

One thing it's not is a fuel dump. The dump nozzle is located in the second from outboard flap track canoe fairing (you would never get certification for a dump nozzle located directly behind an engine).... http://flickr.com/photos/19138132@N00/437592838/ I highly doubt it's a smoke generator for a flight test as they would generally have done this in the flight test area and not close to the airport on final approach in landing configuration. The smoke does look like it's below the flap tip and in the engine exhaust gas path. If it was a test to check flap tip vortices, the smoke would be more defined.

Cheers,

John

While most of that was Greek to me, I would have to agree. I cant imagine them running the plane on one engine, but weirder things have happened. An oil burn makes the most sense of all the other suggestions here.

Good evening.

Aren't the landing gears lowered? Wouldn't this indicate that the plane is not so high in the air?
Could it hence be that the Contrail - if it is one - we see is generated by a plane high in the air and hidden to our eyes by the wing?

Just a suggestion.

Best,

Ferroviarius

In testing, they may have the gear down at higher than normal altitude.

Contrails are normally generated at higher altitudes but in some conditions they can be generated at any altitude.

I think Ferroviarius was trying to say it could be a contrail from a higher flying aircraft that is hidden from view by the A380 wing.

I still go by my theory in reply 10 as a contrail ot high altitude wouldn't difuse as quickly as this one does.

I'll definitely agree with BoeingFixer. From the blueish color of that thing, it's gotta be oil...

I haven't heard anything concerning engine problems or inflight shutdowns during certification (BTW are those the EA or RR?), but then I doubt we'd hear anything about it anyway. When flying with uncertified engines, that's the kind of thing you can expect, especially considering those engines take a serious beating during proving flights.



Looks like I picked the wrong week to quit posting...

I think this photo gives us the answer, for the smoke/contrail.

What they are using this to test is another question.

Hi
just replying to this quote.
This thread was initially in the photography forum.ANET removed it and put it in here after i had already started a new thread in tech/ops.Hence two threads on the same topic

First I've ever heard of a smoke producer being placed in the engine exhaust cone. Looks more like the first start of a new engine burning out the inhibiting oil or they could be trying to find out the malfunction that produced the original in-flight picture.
