BMI A320 Strange Smoke at Dublin

charliehotel

I only noticed this when I played back the video at home. Look at 01:19, it seems like smoke/vapour coming from the left engine, any opinions on this?

Storm 10

Just passing a wet part of the runway and blowing away the water

Looks like its just the jet blast cleaning the runway as the pitch is increased.

Yep just standing water on the runway getting blasted as the aircraft rotated.

Nothing to see here....

But doesn't it exit from the engine? It isn't just being blown from the runway surface, it comes from the engine

I think (s)he was referring to the thread in general

No it's not from the engine. The compressed air coming out of the engine at high speed causes the water to vaporise and look like smoke, but it's not from the engine.

The exhaust gas is directed onto the runway which blows whatever water/dust and other general crap up......

I know.

I highly doubt that it was anything serious (if even anything notable at all), I just found it to look rather strange.

If you actually look at the video it appears to come from the engine. It is directed from the engine, not off the runway as I first suspected, just look at the video and you'll see it exiting from the rear of the engine, it is clearly visible in the video

It doesn't appear to be smoke coming from the engine. Just air which blew the water from the runway as been said before.

Its most def just a bit of water being blown by the jetblast as the Aircraft pitches up and the jetblast is directed onto the runway,here's a video from the same day,1:04 into it you will see the same bit of water getting blown

What you see coming from the engine is the shimmering effect of the hot exhaust gas, which defracts the light coming from beyond, like the shimmering you get above a hot road on a sunny day. This air in turn blows the water off the runway. Nothing more than that.

Same thing here for a Aer Lingus A320 taking off from Cork. Just a damp runway as already mentioned by previous posters.

That seems exactly it Su Campu!

..I knew the other explanations were too simplistic

Defracts is an interesting work.... Is it like a negative form of refraction similar to deceleration
