This was taken a few days ago near toulouse.Do you think she is running on one engine or is there a problem.
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.
