Crosswind Test vid, B777 and 747SP.
 
Nice video of crosswind capability testing in the 777 and 747SP...



Crosswind vid

WMV format.

Geez!
Whats the demonstrated max crosswind for a 747?

Whats the demonstrated max crosswind for a 747?
30kts.

Bendy 10th Aug 2005 22:38

Now 35 (used to be 30 + 5 Knot gust allowance)

Sheesh!
Is this the recommended x-wind landing technique? They didn't seem to make any attempt to kick 'em straight - perhaps this was a test of sideways loads on the gear?
I've seen similar x-wind techniques at BK, in a 152 :rolleyes:

They can't really do the 'wing down' xwind technique, there are big engine-thingies in the way... :uhoh:

Man what a great video.......awesomely capable aeroplane. The mighty 757 rattles and shakes when you abuse it like that!

:)

Thats Tops!
 
Believe that even more than 35kts can be done in a 744.....wouldn't like to say who did it though.

J:ok:

Triple 7 is good for 38kts x-wind autoland on one engine!

Vetical Limit 16th Aug 2005 02:27

Hows about that inspirational music that goes with it.

Just makes me want to get up there and start landing in a cross-wind! ;)

stable approach 16th Aug 2005 02:46

The Messiah,
crosswind limit for autoland is 25kt.

The Messiah 17th Aug 2005 01:08

It is only 25kts when landing weather minima are predicated on autoland ops. Other times like day VMC it is the a/c limit which as I said is 38kts.:ok:

Awesome video on the venerable B777!!

Was watching video with a mate, and he commented on the main gear on the B777 being aligned with the runway, when the rest of the aircraft is not?!

I mentioned that I thought the B747 body gear did this, but that I was unsure about the B777.

Anyone have any idea?

SkySista 17th Aug 2005 09:33

nice vid, does anyone know what it says (or even what language?) was thinking Spanish or Portuguese but I have no idea.... :}

The Messiah 17th Aug 2005 10:39

777 main gear and 747 body gear have no ability to do anything but stay inline with the longitudinal axis always.

On the ground the rear wheel pair on the 777-300 will turn but thats all.

AIRWAY 17th Aug 2005 13:00

It is Portuguese...

When i get home later on i shall translate it. :ok:

shortandsmelly 19th Aug 2005 13:01

You home yet, AIRWAY? :D

I think he's referring to the text on the video, I would like to know what it says aswell.

Um, no.
The entire body gear on the 747 turn in the opposite direction to the nose gear, when on the ground.
I can't remember the figures off the top of my head but they start at about 10° nosewheel steering and move at about 10% as much as the nosewheel.
