notice no attempt to put the left wheel assemblies down first even slightly to reduce the overall impact

Nor the 747, not unless you want to scrape a pod.
or punch the wing gear through the top of the wing like the 747.

Now if he had just learned and used the Jacobsen Flare, all would have worked out OK.

Wouldn't it :rolleyes:

Jacobsen Flare??

Isn't that a cut of trouser?

Sorry mate, don't understand what you're trying to say. Wally Mk 2 points out that no attempt was made to put the upwind side of the aircraft on the ground first to help counter the effect of the crosswind, as "a technique used by every sized A/C at times". A380-800 Driver tells us this is not the case in the A380 and I agree it is not a technique used on the 747, thereby showing the technique is not "used by every sized A/C at times" and that there was nothing wrong with the way the Oshkosh driver landed with his wings level.

If you're telling me that I am mistaken in my understanding of 747 crosswind landing techniques then let's not bog down this thread but start a Tech Log thread and ask along the other pilots with several thousand hours in them.

Whether the technique not to use the traditional method of ldg in a x-wind IE: into wing U/C down first is academic 'cause it IS used a lot whether intentionally or not. You Tube show many such ldg's in wing mounted pod engined craft.
I used to spend many an hour at Tulla in a previous life watching the heavy metal "arrive" in x-wind situations, you could write a book on the amount of different ways these these so called experts where trying to slam down a few hundred tonnes of almost out of control metal inc QF not just the Asian jobs!

Sorry for my ignorance, but what's PIO?

Pilot Induced Oscillations
Ah .. I see. Thanks for that.

Thanks Training wheels, I too was sitting here thining wtf?

X-wind Technique
 
Book procedure:
  • flare
  • rudder to align with centreline
  • aileron to keep wings level
  • land

My usual technique:
  • land
  • rudder
  • flare
  • level wings

With apologies to those I've plagarised this from!

But seriously - B747 Flight Crew training manual (Boeing version) says not to put wing down into wind. I suspect A380 is the same. 7 degrees AofB I think from memory before pod strike - not worth the risk for a smoother touch down!!

:D:D:ok:
Love it.

Come on - it wasn't that bad.

OZBUSDRIVER 30th Jul 2009 22:24

Not to forget...She would be as light as....regardless of size, that is a lot of flying surface with very little to do but go with the wind. Good Job to the PF:ok:
I reckon you gotta get it solidly planted before all the little goodies start doing their thing to turn it into a 200tonne 18 wheeler....or is that 24?:}

Like kicking a cub in a stiff xwind!

I see your heavy landing and raise with the pics of the wing tip damage to the A320 in the above vid. Would have ben a hoot to be in some of those go arounds.

Wally said: notice no attempt to put the left wheel assemblies down first even slightly to reduce the overall impact, a technique used by every sized A/C at times.

Sounds like Wally thinks it's a good idea to put one leg onto the ground first to absorb impact, NOT to counter the effect of the crosswind.

Maybe we should ask him. Where's Wally?

I've never heard of any sort of technique like that for ANY size aircraft. Why TF would you absorb the landing shock with ONE leg when you could absorb it with TWO? Is this taught nowadays?

Personally I think it's a good idea to lower the into-wind wing to counter the effects of the crosswind - but not on an Airbus, which is programmed to do its own thing, not what the pilot happens to want.... but hey it DOES have a fold-out dinner table.

I see that the driver put down a near 4 pointer, good stuff. Had it continued to roll onto the right wing gear with ineffective flare with a few hundred ton slamming onto the deck on one gear, there is a good chance the wing gear would poke its head out above the wing as has many 747's in the past. Thats all.

YoDawg 31st Jul 2009 11:08

Maybe there was an underground creek at the threshold end of the runway... or a plowed field.

"watch the wing go down, up, down and back up again"
...the only PIO going on is from this bloke's word hole
