News footage of Emirates A380 arrival into JFK

Not sure of which runway they landed on (I suspect 22L) but it appears by the footage it was a bit of a turbulent day (note the movement of the rudder on final and aileron deflection short final).

Interesting footage you don't often see (taken from their news helicopter).

Superjumbo Jet Lands At JFK - Videos - WNBC

Edit: watched the video again and it definately was 22L.

hmm.. thought it was the #4 engine, ( i may be counting the wrong way!) the reverser didn't deploy, any one who knows a bit regarding the A380's engines, if it was intentional or a fault?

There is a good reason for that... there is no reverser on Eng 1 and 4

Reversers only fitted on engines 2 and 3!! Nothing wrong

Impressive to see such a big bird bouncing around. For sure the wind was at the party. I suppose external reverses are not fitter because the engines are too close from the grass (or sand ) with such a span...

I was on there, and the direction changes were not noticable. It was impressive how efficiently the (2) thrust reversers managed to slow the a/c so quickly. According to the captain, they used a shorter runway than planned due to late wind direction change. Great flight (both ways!).

Use of rudder on short final is really impressive.
What's your opinion: are these rudder inputs made by the pilot or AFS? If done by the pilot, well, that's a new landing technique on a bus.

Good question and one which i'd like to know the answer to as well.

You certainly don't want to be using rudder at all on big jets these days unless you lose an engine or it's xwind T/O or landing. These things aren't cessna172's. Having never flown Airbus in my life ( shame! ), I would like to hear from someone in the know. Is the system on the A380 much different to the rest of the Airbus FBW fleet?

No. The last 200ft no one really knows who does what or where does the input come from......

With an Airbus FBW, you select the attitude you want, and the ELAC, FAC's and SEC's (depending in type), move the flight controls surfaces to achieve the demand selected. I know the 380 might be different again, however!
The approach was on 22L, VOR approach, which is offset, so for a co-ordinated turn on to the runway track, rudder input will happen.

Nothing sinister, i'll ask the Missus, she was on the flight By all accounts it is a very quiet ship and the pax loved it!

Thanks for the explanation. Just seemed a lot of rudder to me but then I guess it's a lot of plane!

That last 200ft you talk about. Every landing's like that for me!

Yeah ....
sort of reminds me of the joke where on retirement day the missus files for divorce telling you that she always faked them and the fleet chief shakes your hand good bye telling you the side-stick was never connected ....

What i found intrigue-ing is how the wings unloaded on touchdown, now that is spec-tac!!

Yep...you'd better be on the ground before it happens

Unfortunately, I think it's almost impossible to say for the rudder just by watching the video...PRIM, SEC's actions or whatever they called it on that one are transparent to the user.
There are only 2 lucky guys who could shed the light.
Am not a mechanical engineer, but one of the reasons could be turn coordination (even for small inputs?), momemtum equilibrium,...even if a rudder seeming to go repetitively from left to right looks strange to me...

We'll find out by flying it...

"And that's a 6 from the East German judge".

I really hope none of my approaches are ever televised.

You've gotta love that wing flex on touchdown.

You do that on a landing, you get sacked. My buddy ex-AA turned quite pale when he saw this kind of deflection.
At least i now know where the overweight originates on this behemouth: Strengthening structure for the finn.
