Crosswind Landing Gear-

In the video at this post
we discussed, in the comments,
the fact that the gear on one airplane looks as if
it is canted in order to absorb the stresses

of landing in a strong crosswind.

One of the neat things about Blogging is how our
blog-family comes up with
answers to questions.


sent me the addresses of a couple of his friends
that flew Boeings for the airlines.
Both responded to my notes....

Both are Viet Nam Vets,
so I've added new members to my "family". (Thanks TWD!)

"I flew B727's for UPS and B727's /B757's for Northwest
and have several
thousand hours in Boeing products.
The video of the cross wind landings of

Boeings was made at an airport in South America,
can't remember where,
they have high sustained cross winds during
certain parts of the year.
is where Boeing takes their aircraft to test the max
sustainable cross wind
component allowable so they
can validate the engineer's estimates for the

aircraft manuuals. The aircraft are all rigged with
sensors and
instrumentation to measure stress
on various parts of the airframe.
And no,
the gear geometry doesn't adjust for wind component
like the C5 does.

What you see on the video is distortion due to heat
and debris in the wind.

Every time I see that video I have new respect for
Boeing machines.
build a tank, Airbus builds a Humvee."

So there ya have it-
Tough gear, but it doesn't really do anything out of the

ordinary in order to land in strong crosswinds.



Glad to see that Rudy and Tom got back to you. They're both a couple of great guys.

Thanks for posting.

Appreciate the answer. My DNA doesn't like not knowing those kinds of answers.
New font is hard on old people to read, Bro


I think ol' GB just copied and pasted it from the email. Also, you can enlarge it by using the "view" tab at the top of your browser.
