and what is the published max demonstrated crosswind ??
less than 20knts in my guess..


I've landed my 172 in 30 knot crosswinds, as in 25g40 knot winds
perpendicular to the runway. Sure as hell not with more than one notch down,
though. Fun ride it was.

The number in the book is for a plane at gross weight with the engine at
idle. It's the number at which the rudder runs out of effectiveness to keep
the nose aligned with the runway. So you blow it over with the prop. Of

I sure hope your instructor didn't come up with that.

It has absolutely nothing to do with the planes real capabilities.

The figure in the book has only one meaning. It was the wind on the
day the cross wind landing capability was tested and has very little
to do with what the plane can actually do in stronger wings.

My Deb has a 12 knot demonstrated cross wind component. I've taken
off and landed a the cross wind component of 25.

course if it's a short field and you're near gross, then you're going to be
a lot closer to what the book says. But a 15-kt crosswind is nothing for a
lightly-loaded plane as long as the pilot knows what he's doing.

It depends on the airplane.
If the slip to land is used you know if you have enough aileron and
rudder to keep the plane tracking and aligned with the runway.
